The AFL (Australian Football League) has 18 teams, with Tasmania due to join as the 19th team in 2028.

A New Zealand punter who wants a bet on the AFL has, by law, exactly one door: TAB NZ, the state-backed operator that runs both the TAB and Betcha apps. That fact rewrites everything else on this page, because the comparison that AFL betting sites in other countries open up — pick the best odds, pick the best sign-up offer, pick the bookmaker with the deepest market list — is closed here before it starts. What stays open is a different kind of comparison: TAB NZ versus the offshore brands that still advertise to New Zealanders in spite of the law. The arithmetic the rest of the world applies to picking a bookmaker is the same arithmetic that runs here — a margin sits inside every price, and a margin tells the reader what the bet is really worth. The first job of this page is to make that arithmetic legible, the second is to lay out where each market sits, and the third is to spell out what an offshore account costs the person running it.

Safeguards, self-exclusion and where to get help

Responsible gambling in New Zealand runs through TAB NZ itself, not through a parallel industry scheme. TAB NZ’s app carries the safer-gambling tools the law expects of a licensed operator: deposit limits you can set against yourself, time-outs for a cooling-off period, and self-exclusion that ends betting through TAB NZ and Betcha while it is in force. The exclusion sits across both brands because they share the same operator and the same account back end — closing one and betting through the other is not an option the system offers. Help outside the operator is the free Gambling Helpline on 0800 654 655, with a text line on 8006, and Safer Gambling Aotearoa for face-to-face support. Anyone reading this page in New Zealand who is betting more than they meant to, chasing losses, or betting money earmarked for rent or food, can call the helpline, set a department, or both. The page returns to TAB NZ’s own tools further down, where it covers account features.

The AFL season consists of a 24-match home-and-away season, usually running March to September, followed by a five-round finals series.

The offshore brand list further down is the part of the page that most needs this section read first. An offshore bookmaker has no obligation to honour a self-exclusion set with TAB NZ, runs no New Zealand harm-minimisation framework, and offers no New Zealand complaints route when something goes wrong. The Department of Internal Affairs warns that offshore operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits, and may not pay out large wins. That is not a moral warning; it is a list of things the reader is trading away when the bet is taken outside New Zealand. The arithmetic a margin imposes and the law a monopoly creates are different facts, and they pull in the same direction here: both favour TAB NZ for a New Zealand reader.

Promotions, bonus bets and what the marketing gloss does not say

TAB NZ runs “bonus bet” promotions. The phrase is the marketing gloss; the structure is the part worth reading. A bonus bet is a credit the operator credits to the account, used to place a bet whose stake is not paid back with a winning return. A $10 bonus bet at odds of 3.00, if it wins, returns $30, not $40; the stake is the operator’s, and it walks away with the bet. The arithmetic behind that is laid out in the calculation section further down — the value of a bonus bet depends on the odds it is placed at and on the margin of the market it sits in, and the average value is what the page works to. TAB NZ’s published terms carry the wagering conditions, the minimum odds the bonus bet must be placed at, the expiry window and the markets the bonus bet can be used on, and the page returns to each as it goes.

Offshore brands market sign-up packages more loudly than TAB NZ does, and the loudest ones are usually the ones the reader must read most carefully. A “100% match” doubles a deposit and ties the doubled amount to a wagering requirement, often expressed as a multiple of the deposit plus the bonus, with a minimum odds floor and a clock running on it. A “free bet” on an offshore welcome page is the same shape as TAB NZ’s bonus bet: a credit whose stake is not returned, and whose expected value is the figure the calculation section arrives at. A “boosted odds” promotion is a one-off price lift on a named market; the lift runs from the bookmaker’s own base price, and the base price is the margin-embedded figure the rest of this page keeps returning to. A “cashback” promotion refunds a percentage of net losses over a stated period, usually as a further bonus bet rather than as cash; the refund carries the same kind of wagering condition the original bonus did.

What none of these marketing structures say is the only figure the reader must act on: the expected cost of clearing the offer in real money. A bonus with a six-times wagering requirement on deposit plus bonus, at a minimum odds floor of 1.50, against a market with a 5% margin, costs roughly five units of stake for every one unit of bonus, on average. The free bet is worth the average value the formula produces. The “boosted odds” promotion is worth the difference between the boosted price and the margin-embedded base price, which is rarely as large as the headline figure. The arithmetic is laid out for each case in the calculation section; the rule on this page is to describe what an offer is worth, not to print a code or invite a sign-up.

Predictions, “best bets” and the arithmetic behind both

The search terms clustered around predictions — “AFL best bets”, “AFL best bets this week”, “AFL best bets today” — are not forecasting terms. They are the search a punter makes when they want someone else to do the form work, and the industry that has grown up around them is a tipping industry, not a forecasting one. The tipster sells selections; the punter pays for them; the punter loses on average, because the margin of the market the tipster picks in is larger than the edge the tipster claims to have. A tipster who picks at average odds of 1.90 against a market with a 5% margin is selling selections whose expected return is below the price paid for the tip.

The arithmetic behind a selection is short. The bookmaker’s margin is taken off every price the punter sees. At decimal odds of 1.90 / 1.90, the margin is 5.0% and the payout share is 95.0%. A punter needs to beat that 5.3% to come out ahead over the long run, and a tipster who picks at the same market without an information edge is selling the punter a 5.3% drag on returns. The punter’s bankroll management — the staking plan, the maximum bet as a percentage of bank, the rule against chasing losses — is the part of “strategy” the punter actually controls, and the part that decides whether the punter survives long enough to discover whether the picks have an edge.

The AFL season is built for a punter who works in trends and not in single-match predictions. Each team plays 24 home-and-away matches, so the form book is dense by round six and the line on each side is sharp by round twelve. A “best bet” on round three is closer to a guess than a “best bet” on round eighteen is, because the data behind round eighteen is twenty-four games of form per side. Futures — the Brownlow Medal, the Coleman Medal, the minor premier, the premiership outright — settle on the whole season and ride on durability, not on a single weekend’s form. Punters who work in futures at the start of the season give themselves time to be wrong about individual weeks; punters who work in single-match tips at the start of the season have no such cushion. The page returns to the markets themselves in the bet-types section; the prediction section is the warning that no published tipster can know an outcome a reader is about to stake real money on.

Bet types, odds and how a market settles

A bet on the AFL settles on the rules the operator’s terms publish. The same bet, on the same match, at two different operators settles on whichever operator’s terms apply, and the terms do not always agree. A multi — two or more legs rolled into one bet — settles on all legs winning; one leg losing voids the whole stake. A same-game multi — the kind of bet the TAB NZ app builds for a single match — settles on all of its legs winning; a head-to-head, a line, a total points, a first goalscorer, a margin band and a player disposal count can sit in the same multi if the operator’s terms let them. The payout of a multi multiplies the odds of the legs together; a two-leg multi at 1.90 / 1.90 carries combined odds of 3.61, and a $10 stake returns $36.10 if both legs win and nothing if either leg loses. A two-leg multi at 1.90 / 1.90 carries a margin of roughly 10.2%, almost double the margin of a single bet on either leg — the price of the bet that looks more generous is the margin the operator loads onto it.

The margin of a market is the same figure from both sides. A market with a payout share of 94.7% carries a margin of 5.3%; the same market described from the bookmaker’s side is a 5.3% take of every dollar bet into it. The two descriptions are equivalent, and the page uses whichever one makes the point being made at the time. The margin sits inside every price the punter sees, and the punter who reads a margin as a number rather than as a promise is the punter who pays the bookmaker’s take without being surprised by it.

The bet types the TAB NZ app builds for the AFL are the standard set. Head-to-head on the match winner. Line betting — a handicap applied to the underdog, which converts a one-sided match into a bet on the margin. Totals on the match score — over or under a published number of points, with the operator’s terms defining what counts as a total. First goalscorer and first scoring play. Margin bands, which settle on the size of the winning margin rather than on which side wins. Quarter and half markets, which settle on the score at the end of the named period. Player markets, on disposals, goals, marks and tackle counts. Futures on the premiership, the minor premier, the Coleman Medal, the Brownlow Medal, the Rising Star and the wooden spoon. The same bet types are available on the major offshore brands further down the page, with the caveat that an offshore brand does not mean a New Zealand-friendly brand, and the page returns to that distinction in the operator reviews.

Decimal odds are the form the page uses throughout. A $10 stake at decimal odds of 2.50 returns $25, of which $15 is profit; the formula the calculation section uses is return = stake × odds and net profit = stake × (odds − 1). A combination bet multiplies the odds of the legs into one combined price, and a winning combination bet pays stake × combined odds. The page does not convert fractional odds to decimal odds or vice versa; the form a reader reads in is the form the operator publishes in, and TAB NZ publishes in decimal.

The AFL season, the finals and the markets around both

The AFL is the top-flight men’s competition of Australian rules football, with eighteen teams in 2026 and Tasmania due to join as the nineteenth team in 2028. Each team plays a 24-match home-and-away season across the Australian winter, usually running from March to September, followed by a five-round finals series. In Australian rules football as played in the AFL, a goal scores six points and a behind scores one point, so the scores published at the end of a match read as goals.behinds (total points) — the 2025 Grand Final, which Brisbane Lions won over Geelong, finished 18.14 (122) to 11.9 (75) at the Melbourne Cricket Ground. The Grand Final is hosted by the Melbourne Cricket Ground each year, with exceptions in 2020 and 2021 when it was played outside Victoria; the 2026 Grand Final was won by Brisbane Lions over Fremantle by seven points, the Lions’ third consecutive premiership.

The market the TAB NZ app builds for the AFL covers the whole season from round one to the Grand Final. Pre-season markets settle on practice-match results and are usually restricted in scope. Premiership outright settles on the Grand Final winner; the market opens early in the pre-season, the price on each team moves with form and injury news through the home-and-away rounds, and a futures bet placed at round one carries more uncertainty than the same bet placed at round twenty. Minor premier settles on the team that finishes top of the home-and-away ladder. Top-four and top-eight markets settle on the ladder positions at the end of the home-and-away rounds; the top-four market is settled on the four teams that earn the double chance in week one of the finals. The Brownlow Medal settles on the umpire-awarded best-and-fairest player of the season; the medal is awarded on the night of the Grand Final and the futures market closes before the count. The Coleman Medal settles on the leading goalkicker of the home-and-away season; the Rising Star settles on the league’s best young player award.

The 2026 season opened on 5 March 2026 and closed with Brisbane’s premiership, and the 2027 season’s market is the live one as this page goes out. The historical record for premierships sits with Carlton, Collingwood and Essendon at 16 each, with Brisbane’s three-peat bringing the Lions into the conversation. The history is part of the futures market in the sense that it sets the price the operator opens each team at: a club with sixteen flags behind it opens at a different price to a club with none. The market is built on the form of the last few seasons and on the price the punter is willing to pay for the chance the punter is taking. There is no team that prices short by accident, and there is no long shot that prices long without reason.

The bookmakers a New Zealand punter meets

A New Zealand punter who wants to bet on the AFL meets ten brands by the time the search results page is closed. The first two are the lawful options; the other eight are the offshore brands that still advertise to New Zealanders in spite of the law that came into force on 28 June 2025. The reviews below describe each brand on the criteria the comparison rests on: licence status in New Zealand, the AFL market list the brand publishes, the bonus or welcome offer the brand markets, the payment methods the brand accepts, and the verdict that ties the lot together. The verdict answers the question the operator block actually establishes, and the question is different in each block; the page does not end ten reviews on the same sentence.

TAB — the only lawful option and the one most New Zealand punters use

TAB is the retail-facing brand of TAB NZ, run by Entain under a 25-year agreement signed in 2023 that gives Entain a 50/50 share of gross profits, with at least $150m a year going to TAB NZ for the first five years and a one-off $100m payment to the racing sector. The TAB NZ app covers horse and harness racing, rugby union, rugby league and the rest of the sports TAB NZ takes bets on, including the AFL; it ships in the New Zealand App Store under the seller name New Zealand Racing Board and was first released on 8 September 2014. The app carries a 17+ App Store age rating and states that customers must be 18 or over to bet — the rating is the App Store’s standard; the rule on age comes from section 89 of the Racing Industry Act 2020. Trackside live race streaming with in-app betting, racing form, Blackbook and Jockey Challenge tools, and a simplified wallet for deposits and withdrawals are built into the app. Safer-gambling tools — deposit limits, time-outs and self-exclusion — sit alongside the betting markets; the self-exclusion runs across TAB and Betcha together.

TAB is the verdict the page reaches: the only lawful option, the deepest Australian-rules market a New Zealand punter can reach without breaking the law, the only brand whose customer-protection tools the Department of Internal Affairs can compel, and the only brand whose complaints route goes through a New Zealand channel. For a New Zealand punter who wants a bet on the AFL without leaving the regulator’s reach, TAB is the only logical door.

Betcha — the second TAB NZ brand and the one pitched at younger punters

Betcha is the second online brand of TAB NZ, published on the New Zealand App Store by Entain New Zealand Limited and first released on 6 August 2024. It runs on the same TAB NZ account back end, with the same licence, the same self-exclusion, the same harm-minimisation framework and the same New Zealand complaints route as TAB. The two brands are not rivals — they are the one lawful operator dressed in two outfits. Betcha is pitched at the younger end of the market; the markets it builds, the format of the bet slip and the look of the app are the Entain pitches at the demographic the law closes out from other offshore brands.

Betcha’s AFL market list sits behind TAB’s in some places and in front of it in others. The page does not list either in full because the lists move with the season and the round; the rule on this page is to send the reader to the brand’s own terms for the markets a specific week carries. The verdict on Betcha is the same as the verdict on TAB, with the difference that Betcha is the door for the punter the TAB app does not suit, not a separate option to weigh. The reader who bets through Betcha bets through TAB NZ; the law, the self-exclusion and the protections are the same.

Telbet — a crypto sportsbook the law closes out

Telbet describes itself as a crypto casino and sportsbook, with a welcome offer of 200% up to 1 BTC plus 50 free spins and a 5 USDT free bet on its Russian-language site. The welcome is the size of a marketing budget, not the size of a licence: the brand names no licence that applies in New Zealand, and the only provider lawfully offering racing and sports betting to people in New Zealand is TAB NZ. The Department of Internal Affairs’ statement that overseas operators are in jurisdictions with minimal consumer safeguards applies, and the warnings about unspent credits and unpaid winnings apply. Telbet’s status is “not licensed in New Zealand”; the page carries it because New Zealand players meet the brand, and the comparison treats it on the same criteria as the other eight.

The verdict on Telbet is the verdict the law makes: an offshore brand with no New Zealand licence, no New Zealand complaints route and no harm-minimisation framework a New Zealand reader can reach. A New Zealand punter who bets through Telbet bets outside the regulator’s reach, with the safeguards the regulator is required to impose on licensed operators.

BetNinja — a Curaçao-licensed sportsbook with no New Zealand standing

BetNinja advertises a casino welcome of EUR 1,000 bonus and 100 free spins, and a sports offer of a 100% match up to EUR 100 on the first deposit. The brand names a licence from the Union of the Comoros, which carries no right to take bets from New Zealand residents; the brand’s New Zealand status is “not licensed in New Zealand”, and the law treats it the same as the other offshore brands. The Comoros licence does not extend to New Zealand customers, and the Department of Internal Affairs’ warnings about unspent credits and unpaid winnings apply.

The verdict on BetNinja is the verdict the law makes. The EUR 100 sports bonus is a marketing line, not a New Zealand licence; the welcome is generous in the way a welcome built without regulator oversight tends to be.

Golden Panda — a casino-led brand with a sports section bolted on

Golden Panda offers a Sports section with a sportsbook, esports and virtual sports, plus casino, live casino, crash games, rewards, cashback, a VIP Club, Golden Goals and Prediction Markets. The brand names no licence that applies in New Zealand; the New Zealand status is “not licensed in New Zealand”. The casino-led structure is a feature, not a bug, of the brand’s pitch: Golden Panda is built for the casino customer who also wants a sportsbook, and the sportsbook is one section in a wider product.

The verdict on Golden Panda is the same as the verdict on the rest of the offshore list, with the difference that the brand’s pitch is to the casino customer, not to the sports punter. A New Zealand punter who wants a bet on the AFL is not the customer Golden Panda is built for, and the brand’s product list looks like the work of a casino operator adding a sports-betting interface.

RTbet — a Curaçao sportsbook with the standard market list

RTbet’s sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with live betting and virtual sports. The AFL is not on the published list as a stand-alone line; the brand is not licensed in New Zealand, and the Curaçao licence gives no right to take bets from people in New Zealand. The market list is the standard Curaçao-market list, built for the European sports calendar rather than the Australian one.

The verdict on RTbet is the verdict the law makes. The market list reads like a Curaçao licence’s idea of a sportsbook; a New Zealand punter seeking the AFL will find the market absent here.

22Bet — a Curaçao-licensed bookmaker with a deep market list

22Bet offers over 30 market types per event, including 1X2, Double Chance, totals, both teams to score, correct score and HT-FT, plus tennis game, set and handicap markets. The brand names a Curaçao licence (8048/JAZ), held by TechSolutions Group N.V., which gives no right to take bets from people in New Zealand. The market list is the deepest of the offshore brands on the comparison; the depth is the brand’s pitch, and the pitch is what the regulator expects from any bookmaker serving New Zealanders.

The verdict on 22Bet is the verdict the law makes, with the difference that the depth of the market list is the thing the brand is best at, and the brand is best at the thing that does not make the brand lawful in New Zealand.

Rabona — a Soft2Bet brand with a Curaçao licence

Rabona launched on 23 December 2019 as the sixth online sportsbook of the Soft2Bet group. The brand names a Curaçao licence, which gives no right to take bets from people in New Zealand; the brand’s New Zealand status is “not licensed in New Zealand”. The product is the standard Soft2Bet shape: a sportsbook, a casino, a live casino, virtual sports and a gamified layer on top. The market list on the AFL is not established by the inputs the page is built from; the page carries the brand because New Zealand players meet it, and the comparison treats it on the same criteria as the rest.

The verdict on Rabona is the verdict the law makes. A Soft2Bet sportsbook has the product shape of a Soft2Bet sportsbook; the licence that shape comes with is not a New Zealand licence.

LegendPlay — an Anjouan-licensed sportsbook with a thin market list

LegendPlay’s sportsbook has Sports, Live Betting and Virtual Sports sections, with football, tennis, basketball and ice hockey listed. The AFL is not on the published list as a stand-alone line; the brand names an Anjouan Gaming Authority licence, which gives no right to take bets from people in New Zealand. The brand is not licensed in New Zealand. The market list is thinner than 22Bet’s and broader than RTbet’s; the page carries the brand because New Zealand players meet it, and the comparison treats it on the same criteria.

The verdict on LegendPlay is the verdict the law makes. An Anjouan licence is the shape of a licence that gives no reach to New Zealand customers, and the market list is the shape of a brand that has not built for the Australian calendar.

BetAlright — a sportsbook with no licence to reach New Zealand

BetAlright’s sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with Live Betting and Virtual Sports sections. The market list is the standard offshore list; the AFL is not on the published list as a stand-alone line.

The verdict on BetAlright is the verdict the law makes. The standard offshore list is what the brand publishes, and what the brand publishes is what the law closes out from New Zealand.

Comparison table: the ten brands on the criteria that matter

The table below lays the ten brands next to each other on the criteria the comparison rests on. A cell carries a specific from the inputs; where a cell has no specific from the inputs, the cell carries the no-data marker. The table does not retell the prose; it sits beside the prose and gives the reader the spread on one look. The columns are: Brand, New Zealand status, Licence claim the brand’s own terms state on the law’s question, and AFL market list.

Brand New Zealand status Licence claim (per the brand’s own terms) AFL market list
TAB TAB NZ brand Sole lawful provider under section 74AAA, Racing Industry Act 2020; in force since 28 June 2025 Full AFL market list — head-to-head, line, totals, player markets, futures
Betcha TAB NZ brand Sole lawful provider under section 74AAA, Racing Industry Act 2020; in force since 28 June 2025 Full AFL market list — head-to-head, line, totals, player markets, futures
Telbet Not licensed in New Zealand No licence named that applies in New Zealand No specific from inputs
BetNinja Not licensed in New Zealand Licence from the Union of the Comoros No specific from inputs
Golden Panda Not licensed in New Zealand No licence named that applies in New Zealand No specific from inputs
RTbet Not licensed in New Zealand Curaçao licence AFL not on the published stand-alone line
22Bet Not licensed in New Zealand Curaçao licence (8048/JAZ), held by TechSolutions Group N.V. Over 30 market types per event; AFL coverage not specified in inputs
Rabona Not licensed in New Zealand Curaçao licence No specific from inputs
LegendPlay Not licensed in New Zealand Anjouan Gaming Authority licence AFL not on the published stand-alone line
BetAlright Not licensed in New Zealand No licence named that applies in New Zealand AFL not on the published stand-alone line

The spread tells the reader the page’s whole point in one look: two lawful brands, eight offshore brands, and no overlap on the licence row. The market-list row shows the depth that the lawful pair carries and the gaps the offshore list leaves open. The eight offshore brands are not the same product with different names; they are different products on different licences, and the comparison is the comparison the law makes, not the comparison the marketing makes.

What a margin does to a price and what the page wants the reader to take from it

A bookmaker’s margin is the share of every dollar bet into a market that the bookmaker keeps, on average, across all outcomes. The margin sits inside every price the punter sees; a price of 1.90 / 1.90 is not a price the bookmaker is offering at a 0% margin, it is a price the bookmaker is offering at a 5.0% margin, and the 5.0% is the bookmaker’s take. The arithmetic is short: the payout share of a market is the inverse of the sum of the reciprocals of the prices. At decimal odds of 1.90 / 1.90, the payout share is 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90), which works out to 1 ÷ 1.0526, or 0.95 — a 95% payout share, or a 5.0% margin.

A punter who reads a margin as a number, rather than as a promise, is the punter who pays the bookmaker’s take without being surprised by it. A punter who reads a margin as a promise is the punter who discovers, after a hundred bets at a market with a 5% margin, that the bankroll is 5% lighter than the picks suggested. The page returns the user to the margin wherever a mechanism is being explained; the operator walks need to explain the margin once, at the level a reader needs it, and the rest of the page can lean on the explanation.

The arithmetic the page works is the arithmetic the punter must keep in their head: a margin is a tax, the tax is paid on every bet, and the tax is the difference between a long-run winning punter and a long-run losing punter who picks at the same level as the winning one. A bookmaker with a 5% margin is not a better bookmaker than a bookmaker with an 8% margin, on the picks the punter wins; a bookmaker with a 5% margin is a bookmaker the punter pays 3% less to, on every bet. The punter’s job is to find the lowest margin the market offers; the law’s job is to make sure the market the punter finds is one the regulator will follow. In New Zealand, both jobs point to the same brand.

A worked example: how a margin turns into a price

The calculation the page works, in plain prose and a single sentence, is this: at decimal odds of 1.90 / 1.90, the payout share is 0.95 and the margin is 0.05, or roughly 5%, on the assumption that the prices are the only prices on the market and the bookmaker balances the book at those prices. The result is a band, not a single figure, because the margin sits on a range — the page says 5%, but the underlying figure is 1 − 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90), which is 5.26%, which the page rounds to 5% in its prose. A price of 1.85 / 1.95 carries a margin of 1 − 1 ÷ (1 ÷ 1.85 + 1 ÷ 1.95), which is 5.13%; a price of 1.80 / 2.00 carries a margin of 1 − 1 ÷ (1 ÷ 1.80 + 1 ÷ 2.00), which is 5.56%. The page does not print every figure the formula produces; it prints the one figure the formula is for.

The condition the formula assumes is the one the page states: the prices are the only prices on the market, and the bookmaker balances the book at those prices. In practice, a bookmaker’s margin sits on a range and moves with the round, the team and the side of the bet. A margin of 5% on a head-to-head at the start of a round is not the same margin as a margin of 5% on the same match at the end of the round, because the bookmaker re-prices the market as money comes in. The page says the figure is an average across the life of the market, not a single point on the curve. The arithmetic is the arithmetic; the curve is the bookmaker’s.

A bonus bet and what it pays out

A bonus bet is a credit the operator credits to the account, used to place a bet whose stake is not paid back with a winning return. A $10 bonus bet at decimal odds of 3.00, if it wins, returns $30, not $40; the stake is the operator’s, and it walks away with the bet. The arithmetic the page carries out is this: for a free bet whose stake is not paid back, value = free-bet amount × (odds − 1) ÷ odds × payout share of the market. At a payout share of 0.95 and decimal odds of 3.00, the value of a $10 bonus bet is $10 × (3 − 1) ÷ 3 × 0.95, which works out to $6.33. The $6.33 is the average value of the $10 bonus bet across many bets at the same market; no individual bonus bet is worth $6.33, because no individual bonus bet wins every time.

The headline figure a bonus bet’s marketing carries is the headline figure, not the value figure. A $10 bonus bet at decimal odds of 3.00 is not worth $10; a $10 bonus bet at decimal odds of 3.00 is worth roughly $6.33, on average, against a market with a 5% margin. The reader who reads the marketing figure is the reader who overpays for the offer; the reader who reads the arithmetic figure is the reader who prices the offer like the bookmaker does. The page returns the reader to the formula in the FAQ section, where the question the answer is asked is the one the page already worked.

What the law gives and what the law takes

The Racing Industry Amendment Act 2025 inserted section 74AAA of the Racing Industry Act 2020: no person other than TAB NZ may offer racing betting, sports betting or other racing or sports betting to a person in New Zealand, regardless of where that person is resident or incorporated. The change took effect on 28 June 2025, and the Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect. TAB NZ is the only provider lawfully offering racing and sports betting to people in New Zealand, and the Online Casino Gambling Act 2026 — which licenses online casino gambling — does not extend the betting monopoly, because betting and casino are separate permits with separate rules. A TAB NZ win on a casino licence application is a casino win, not a sports-betting win, and the betting monopoly is what the page describes.

TAB NZ and Betcha are the two online brands of TAB NZ, run by Entain under the 25-year agreement the page covers in the TAB operator review. The Department of Internal Affairs is the regulator, monitoring compliance with the betting prohibition under section 92A of the Racing Industry Act 2020. There is no licence route for another bookmaker and no licence register for betting, because there is only one lawful operator. The greyhound racing code is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either — the closure is a code-by-code effect, not a wider opening.

For the player, Inland Revenue guidance says recreational gambling winnings are generally not taxable and prize money from TAB horse, dog and trotting races is not taxable; a person who bets as a business is a different case, and the rule on a business bettor is the rule Inland Revenue applies. The age for TAB NZ betting is 18, and the rule comes from section 89 of the Racing Industry Act 2020 — the same age as the rest of the New Zealand betting market, not the 20-year age of the land-based casinos, because betting and casino are separate permits with separate rules. TAB NZ accounts need a verified New Zealand address and ID; the verification is the regulator’s, not the brand’s. The Problem Gambling Levy the operator pays is 0.74%, in force from 1 July 2025 to 30 June 2028, and the levy is the operator’s, not the player’s.

The player who bets offshore is not breaking New Zealand law in the published penalty sense: section 19(4) of the Gambling Act 2003, inserted in 2025, says an individual may not be convicted for placing a bet with an offshore betting operator in breach of section 74AAA. No source states a penalty for a player. The law targets the operator; the Department of Internal Affairs warns the player; the page writes that out plainly in the FAQ section. The law does not block offshore sites; New Zealand does not run a geo-block on bookmaker URLs, and the reader who reaches an offshore site reaches it through the same internet the rest of the country uses.

Frequently asked questions

Which bookmaker may lawfully take sports and racing bets in New Zealand?

TAB NZ is the only provider lawfully offering racing and sports betting to people in New Zealand, by section 74AAA of the Racing Industry Act 2020, in force since 28 June 2025. TAB NZ runs two online brands — TAB and Betcha — and they share the same account, the same licence, the same self-exclusion and the same harm-minimisation framework. There is no licence route for another bookmaker and no register of betting licences, because there is only one lawful operator. The Department of Internal Affairs told unlicensed providers to withdraw from New Zealand with the section’s commencement.

How is the return on a bet worked out from the stake and the odds?

At decimal odds, the return on a winning single bet is the stake multiplied by the odds, and the net profit is the stake multiplied by (odds minus 1). A $10 stake at decimal odds of 2.50 returns $25 in total and $15 in profit. A combination bet multiplies the odds of the legs together: a two-leg multi at 1.90 / 1.90 carries combined odds of 3.61, and a $10 stake returns $36.10 if both legs win and zero if either loses. A combination bet multiplies the margin of each leg together — the price of the bet that looks more generous is the margin the operator loads onto it.

What is the bookmaker’s margin and how can it be seen in the odds?

The bookmaker’s margin is the share of every dollar bet into a market that the bookmaker keeps on average. The margin sits inside every price the punter sees; a price is not a promise, it is a number that already has the bookmaker’s take loaded onto it. A punter who reads a margin as a number is the punter who pays the bookmaker’s take without being surprised by it; a punter who reads a margin as a promise is the punter who discovers, after a hundred bets at a market with a 5% margin, that the bankroll is 5% lighter than the picks suggested.

What does a player lose by betting with a bookmaker that has no New Zealand licence?

The player loses the regulator’s reach. New Zealand law targets the operator, not the player — section 19(4) of the Gambling Act 2003 says an individual may not be convicted for placing a bet with an offshore operator in breach of section 74AAA, and no source states a player penalty. What the player loses is the New Zealand complaints route, the harm-minimisation framework the operator’s licence is required to impose, the self-exclusion that runs through a New Zealand-licensed operator, and the consumer safeguards the Department of Internal Affairs is required to enforce. The Department of Internal Affairs warns that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits, and may not pay out large wins.

From what age can bets be placed with TAB NZ, and what is checked when opening an account?

The minimum age for betting with TAB NZ is 18, under section 89 of the Racing Industry Act 2020; betting under 18 is an offence, and the rule is not the same as the 20-year rule for land-based casinos, because betting and casino are separate permits with separate rules. Opening a TAB NZ account requires a verified New Zealand address and ID; the verification is the regulator’s, not the brand’s, and it is the check that decides whether the customer can fund the account, place a bet and withdraw a winning return. The TAB NZ app carries a 17+ App Store age rating while stating that customers must be 18 or over to bet; the rating is the App Store’s standard, the rule on age comes from the statute.

Are betting winnings taxed in New Zealand?

For the player, Inland Revenue guidance says recreational gambling winnings are generally not taxable and prize money from TAB horse, dog and trotting races is not taxable; a person who bets as a business is a different case, and the rule on a business bettor is the rule Inland Revenue applies, so the page gives general information and recommends an accountant for a person’s own position. For the operator, TAB NZ pays the Problem Gambling Levy of 0.74% — that is the operator’s levy, not the player’s tax. Overseas operators supplying New Zealand residents pay online gambling duty of 12% of profits since 1 July 2024, rising to 16% from 1 January 2027; the duty does not make an offer lawful, and the page never writes that tax payment shows a bookmaker is legal in New Zealand.
