A check of 26 October 2026 against the New Zealand register of operators who may lawfully take racing and sports bets confirms the market is what it has been since 28 June 2025: two online brands of one provider, with no second bookmaker permitted and no licence register to apply to.

Since an amendment to the Racing Industry Act 2020 took effect on 28 June 2025, TAB NZ and its online sister brand Betcha are the only operators allowed to take online sports and racing bets in New Zealand.

The cost of a bet, walked through

A wager is three numbers glued together: the stake, the odds, and the bookmaker’s margin. The first two are visible on every bet slip. The third is invisible, folded into the prices the bookmaker writes, and it is the figure that decides what a winning bet is really worth over the long run.

Stake is the money risked. Odds are the multiplier that turns stake into return, in decimal form. Return on a winning single is stake multiplied by odds. Net profit — what the bettor keeps once their stake is back in the pocket — is stake multiplied by odds minus one. A $10 bet at odds of 2.10 pays $21 back if it wins, with $11 of that being the actual gain. The mechanic does not change when the bet is a combination, a multi or a same-game multi: each leg’s odds multiply together, and the stake runs once against the combined price. A four-leg multi at legs of 1.80, 1.95, 1.70 and 2.05 multiplies out to roughly 11.69; the same $10 pays about $116.90 if all four legs win, and nothing if any one of them loses.

The margin is the share of every dollar wagered that the bookmaker keeps, calculated as the overround (the sum of the implied probabilities minus one) divided by that sum. A two-way market priced at 1.90 / 1.90 has implied probabilities of 52.63% on each side, summing to 105.26%; the overround is 5.26%, and the margin is 5.0%. The margin is invisible on the bet slip; it is folded into every price the bookmaker writes, and a sharper market carries a thinner margin than a softer one.

The arithmetic is plain. Payout share is one divided by the sum of one over each odds — so 1 ÷ (1/1.90 + 1/1.90) works out to 1 ÷ (0.5263 + 0.5263), which is 1 ÷ 1.0526, or about 95.00%. Margin is 1 minus the payout share, which gives 5.0% on this illustration. The condition sits inside the inputs: this is what an evenly priced two-way market at 1.90 / 1.90 produces, and a real TAB NZ football line priced the same way carries a similar 5% margin band; an underdog at 3.40 against a 1.30 favourite adds to 1 ÷ (1/3.40 + 1/1.30), which is 1 ÷ 0.2941 + 0.7692, or 1 ÷ 1.0633, leaving a margin of around 5.95% in the same neighbourhood. A bookmaker’s margin is not a single number across the book — it is a different number for every market, every fixture, every runner and every line, and a sharp bettor’s edge is built on knowing which markets are thin and which are not.

The bettor’s average loss per dollar wagered tracks the margin of the market they are playing in. A bettor laying $1,000 across a string of bets at an average 5% margin gives the bookmaker $50 of expected value, before the line on any single bet ever settles. That is the figure every promotional headline has to clear before it is worth anything.

What a free bet is actually worth

A “free bet” is a token, not cash. Its stake is usually not paid back when the bet wins: a $50 free bet at odds of 3.00 pays $100 in profit, not $150. The average value of that token, on a market of a given margin, is the free-bet amount multiplied by odds minus one, divided by odds, then scaled by the market’s payout share. On a market with a 95% payout share, a $50 free bet at 3.00 is worth $50 × 2.00 ÷ 3.00 × 0.95, or roughly $31.67 in expected profit. The “free” in the name covers a token worth about 63 cents on the dollar at those prices, and the gap widens on shorter-priced favourites. A free bet is not a gift; it is a small-stake bet the bookmaker has already loaded against the player.

How a bonus turns into cash

A “100% deposit bonus” looks like double the money. It rarely is. A $100 deposit matched with a $100 bonus, with a wagering requirement of five times the bonus, asks the player to place $500 of qualifying bets before any of the bonus balance becomes withdrawable. The bets themselves take place at a margin — call it 5% — so the expected cost of clearing is $500 × 0.05, or $25. The player who deposits $100, clears a $100 bonus, and walks away with withdrawable funds has spent $25 of the bonus in expected value to do it. The “double your money” headline is paying for itself as it is read.

The bettor who only bets singles, at minimum odds of 1.50 or higher, and never places a bet that voids the promotion, finishes close to the expected loss. The bettor who deviates — placing a multi with one short-priced leg, betting under the minimum odds, withdrawing mid-clear — usually finishes worse. The closer a player sticks to the route the bonus is built for, the closer their actual cost lands to the expected one.

The ten brands New Zealand players meet, ranked

Two of the ten are TAB NZ’s own brands. The other eight are not licensed in New Zealand. The set is not a recommendation: it is the shortlist of brands a New Zealand reader will see advertised, in a market where only the first two are lawful to take a bet from.

Brand New Zealand status What the operator’s own terms state on the page’s subject
TAB TAB NZ brand (lawful) The Racing Industry Act 2020 gives TAB NZ the only lawful route for racing and sports bets from people in New Zealand; section 74AAA took effect on 28 June 2025.

The “New Zealand status” column is the column the law cares about, and it is the only one where the table carries a clear division. Eight of the ten brands are unlawful for an operator to serve a New Zealand customer, regardless of where the operator is incorporated, and the Department of Internal Affairs told providers doing so to withdraw with immediate effect. The remaining two are not rivals to each other — they are two windows into the same bookmaker, 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 pledged to the racing sector.

TAB — the lawful bookmaker, the long way around

TAB is the brand the Racing Industry Act 2020 names. It is the holder of the only lawful route to a sports or racing bet for a person in New Zealand, and the only place where a dispute can be taken to a New Zealand body if anything goes wrong. The app is published on the New Zealand App Store under the seller name New Zealand Racing Board and was first released on 8 September 2014, with a 17+ age rating. The terms state 18 or older to bet, and a New Zealand address and ID are required to open an account.

The product covers horse and harness racing, rugby union and rugby league and other sports, pre-match and live. Racing form, Blackbook and Jockey Challenge tools sit inside the app, alongside Trackside live race streaming with in-app betting and a single wallet for deposits and withdrawals. The betting menu includes Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie and Big6 on racing, plus Multis and Same Game Multis (a multi whose legs come from one event) on sports. Bonus bet promotions run on the brand’s own terms; no statutory cap on bonus size or wagering terms applies, so the small print is the only place the cost is stated.

For the New Zealand bettor, the cost of using TAB is the margin baked into every market plus the operator’s own terms on minimum odds, deposit ceilings and bonus conditions. The protection on the other side is the same regulator that wrote the monopoly into law: a New Zealand complaints framework, a self-exclusion that applies across both TAB NZ brands, the deposit limits and time-outs that the app surfaces, and the 0.74% Problem Gambling Levy TAB NZ pays on the betting side.

Betcha — the same bookmaker, the newer front door

Betcha is the second of TAB NZ’s two online brands, and it is the same legal entity in a different wrapper. The app was published by Entain New Zealand Limited on 6 August 2024 and covers horse, greyhound and harness racing, plus rugby, NRL, MMA and UFC, NBA, NFL, tennis, cricket, football, motorsports and esports. The greyhound code is one to watch: greyhound racing is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either.

The reason Betcha exists at all is the same 25-year Entain partnership that runs TAB. Two brands, one bookmaker, one licence position, and the same New Zealand-overseen complaints route behind them. The competitive comparison that a reader might expect — Betcha versus TAB on price, on bonus, on margin — does not exist, because the two brands are run as a single operation with the same betting rules and the same risk desk behind them. The choice between them is the choice between two front doors.

Thunderpick — esports-heavy, offshore licence

Thunderpick is an esports-first brand, with CS2, League of Legends, Dota 2 and Valorant as the headline markets and a sportsbook that runs from the Champions League to the NFL, including a cash-out feature on the sports side. The licence behind it is Curaçao (OGL/2024/677/0722), held by Paloma Media B.V., which gives no right to take bets from a person in New Zealand.

The mismatch with the page’s subject is the licence position itself. A New Zealand reader who puts a bet on through Thunderpick is betting with an operator the Department of Internal Affairs has said must withdraw from the New Zealand market, on a licence that grants no New Zealand consumer protection, into a complaint framework that does not reach a New Zealand body. The market depth and the esports coverage are real; the framework around the bet is the gap the page exists to name.

BigClash — sports and virtuals, no New Zealand cover

BigClash runs a pre-match and live sportsbook across international and local leagues, alongside virtual sports and esports on FPS and MOBA titles. The licence is Curaçao (8048/JAZ), and that licence does not extend to taking bets from people in New Zealand.

The cost to a New Zealand reader using BigClash is the same shape of cost as any other offshore brand on this list: the operator’s terms on minimum odds, deposit ceilings, bonus conditions and withdrawal times, with no New Zealand regulator behind them, no New Zealand complaints route, and no guarantee that the small print will pay out the way a TAB NZ bet will. The product may be competitive on price; the recourse is the part the marketing does not name.

Telbet — crypto sportsbook, no local protection

Telbet is a crypto casino and sportsbook, with in-play betting and a My Bets page alongside a separate sports betting rules document, a separate bonus terms page and a separate responsible gambling and AML policy. The Russian-language version of the site advertises a 200% welcome up to 1 BTC plus 50 free spins and a 5 USDT free bet, which is the kind of headline the bonus section above already took apart. No licence is named that applies in New Zealand.

Crypto deposits make the offshore problem worse, not better. There is no bank standing between a New Zealand bettor and the operator, no chargeback route, and no equivalent of a New Zealand credit-card block. The bonus headline and the licence gap live on the same page, and a New Zealand reader has to read past both before they place a dollar.

RTbet — broad sportsbook, no local reach

RTbet’s sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with live betting and virtual sports on the same account. The brand names a Curaçao licence, which does not extend to New Zealand customers, and the same DIA warning applies as for every other offshore entry on this list.

The shape of the cost to the bettor is unchanged. The shape of the protection is: there is none that a New Zealand consumer can reach.

22Bet — deep market list, no local cover

22Bet’s selling point is its market depth: over 30 market types per event, including 1X2, Double Chance, totals, both teams to score, correct score and HT-FT on football, plus tennis game, set and handicap markets. The licence is Curaçao (8048/JAZ), held by TechSolutions Group N.V., which gives no right to take bets from people in New Zealand.

A wide market list is the easiest feature for a bookmaker to advertise, because it is the cheapest to add: every extra market is a row of the spreadsheet and a fresh place to load a margin. The question for the New Zealand reader is whether the markets are tighter than TAB NZ’s, and at what cost to recourse. The answer to the second half is: no New Zealand route exists.

Roobet — esports and US sports, no local cover

Roobet’s sportsbook covers soccer, basketball, tennis, Counter-Strike, FIFA, baseball, ice hockey, MMA and table tennis, with an 18+ age rule in the terms. The licence is Curaçao (OGL/2024/687/0427), held by Raw Entertainment B.V., and does not reach a New Zealand bettor.

The mismatch with the page’s subject is the same one every other offshore brand carries. The protection, on the New Zealand side, is the same zero.

Spinbara — casino-plus-sportsbook, no local cover

Spinbara runs a casino and a sportsbook on one account, with a 100% match up to EUR 100 on the sports welcome and a separate 100% match up to 200 USDT on its crypto sports welcome, plus a casino welcome of 100% up to EUR 500 plus 200 free spins. The bonus terms on the sports side are the kind the bonus arithmetic above already costed: the headline is double the deposit, the clearing cost is the expected loss at the market margin over the wagering requirement, and the figure on the page is what a New Zealand reader compares the bonus against, not the deposit match.

No licence applies in New Zealand. The complaint framework does not reach a New Zealand body. The product is the product; the protection is absent.

Alawin — full sportsbook, no local cover

Alawin’s sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with Live Betting, Virtual Sports and esports as separate sections. No licence applies in New Zealand.

The closing line on this entry, and on every offshore entry above it, is the same: the product is a real sportsbook with real markets, and the framework behind it does not include a New Zealand regulator, a New Zealand complaints route or the New Zealand harm-minimisation rules the lawful operator is bound by. The reader’s decision is whether the price difference is worth the loss of every protection that sits on the New Zealand side of the line.

The fundamentals of how to place a bet

The mechanics are the same on every bookmaker, lawful or otherwise. A bettor opens an account, deposits funds, picks a market, chooses a stake, confirms the bet, and waits for the result to settle. The differences are the size of the menu, the depth of the markets, the speed of settlement, and — most of all — the licence position and the protection that comes with it.

An empty football stadium with floodlight masts at dusk
TAB NZ’s partner Entain runs the TAB business 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.

Account opening at TAB NZ asks for a verified New Zealand address and ID, because the Racing Industry Act 2020 prohibits taking a bet from a person whose identity and place of residence are not confirmed. Offshore books vary: some ask for full ID at sign-up, some ask only at withdrawal, and some ask for neither until a payout is challenged. The first pattern is what a New Zealand reader who loses a dispute will wish they had.

Deposits at TAB NZ run through the methods the operator publishes in its terms: card, bank transfer, and the operator’s own deposit methods. The minimum deposit and the deposit ceiling are TAB NZ’s own. Offshore books add e-wallets, prepaid vouchers and crypto, with the methods and minimums set by the operator and the cost to the bettor set by the network fee on crypto, the card surcharge on card, and the exchange margin on a converted currency.

Picking a market is the part that takes time. A TAB NZ bet on an All Blacks test lists head-to-head, line, total points, first try-scorer, half-time result, and the same-game multi combinations. The odds sit at the prices TAB NZ has written, and the margin sits inside them. The decision is which price is worth the bet, and the only way to know is to compare it to other markets on the same event — a price boost is meaningless without the un-boosted price beside it, and a margin is meaningless without a second bookmaker to compare it against.

Choosing a stake is the part the bettor controls. The bet slip surfaces a return figure and a stake box; the return is stake multiplied by odds, the profit is the return minus the stake, and the rest is the bettor’s own call. The bankroll management is on the bettor, and the operator’s deposit limit is a ceiling, not a budget.

Confirming the bet is the moment the stake is committed. TAB NZ’s terms on bet acceptance, void bets and rule-4 deductions apply; offshore books have their own equivalents, and the small print is the place to look. After that, the bet is the bettor’s until the result settles, and the only operator action that changes it is a void or a rule-4, both of which the operator’s own rules define.

Settlement is the moment the result comes in and the bet is graded. TAB NZ settles Win, Place, Each Way and the exotic bets (Quinella, Exacta, Trifecta, First Four, Double, Treble, Quaddie, Big6) on the dividend the tote declares, and settles sports bets at the price confirmed at placement. Live bets settle as the event happens, and the in-play price at the moment the bet was confirmed is the price that counts.

The statute that made TAB NZ the only option

The Racing Industry Amendment Act 2025 inserted section 74AAA into the Racing Industry Act 2020. The section says 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. It took effect on 28 June 2025, and the Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect.

Betcha is one of two brands, with TAB NZ, that may lawfully take online sports and racing bets from people in New Zealand since 28 June 2025.

The law does not block offshore sites; it puts liability on the offshore operator. An overseas bookmaker taking a bet from a person in New Zealand is breaking New Zealand law, and the Department of Internal Affairs has said as much in writing. The penalty for breaching section 74AAA is not stated in the section, and no prosecution of an offshore bookmaker was found. The player is in a different position: 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, and no source states a player-side penalty.

The bookmaker’s licence is the only column on the table that decides whether a bet is lawful. A New Zealand-licensed brand, in this market, is a TAB NZ brand. There is no second licence to apply for and no register to apply to, because there is only one lawful provider.

The Online Casino Gambling Act 2026 sits beside the Racing Industry Act 2020 and does not overlap with it. The casino law creates a licensed online casino regime and does not extend TAB NZ’s sports-betting monopoly; it does not open a second route to a sports-betting licence. Anyone framing the casino law as a route to a competitive sports-betting market is reading the wrong statute.

What may be bet on

Racing and sports betting from TAB NZ only. TAB NZ takes fixed-odds and tote bets; fixed-odds is the price the operator wrote at placement, tote is the pool dividend declared at the end of the race. The published betting rules define Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie and Big6 on racing, and Multis and Same Game Multis on sports. Live betting is listed in the TAB NZ apps; any statutory restriction on in-play markets is not established, and the absence of a ban is not the same as a confirmed right.

No lawful New Zealand betting exchange exists, and spread betting is outside TAB NZ’s sports-betting definition. Bets on politics and novelty markets: not established. There is no statutory per-bet cap; limits are TAB NZ’s own terms, set at the operator’s discretion. The ban covers events held inside and outside New Zealand, which is why a bet on the Melbourne Cup from a TAB NZ account and a bet on a TAB NZ-listed Super Rugby Pacific match sit on the same legal footing. Virtual (computer-simulated) sport is treated by the 2026 online casino law as casino gambling. Whether esports betting is “sports betting” under the Racing Industry Act is not established, so the lawful route for an esports bet is the same one as for a football bet: TAB NZ.

What it costs the operator to run a bet

On the operator side, TAB NZ pays a Problem Gambling Levy of 0.74%, in force from 1 July 2025 to 30 June 2028. 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 point-of-consumption charge on offshore racing and sports bets ceased on 30 June 2026. None of these figures makes an offshore brand lawful — paying tax in a jurisdiction does not extend a licence into New Zealand, and a tax payment is not a regulatory approval. The bettor’s view of an offshore brand’s tax position is the view of a duty, not a licence.

Player protection, paid for by the levy

The age for TAB NZ betting is 18, and betting under 18 is an offence under section 89 of the Racing Industry Act 2020. Land-based casinos are 20, and the two ages are not the same; the lower one applies to betting, the higher one to the casino floor. TAB NZ accounts need a verified New Zealand address and ID, and the verification is the first line of protection against a minor or a non-resident opening an account.

TAB NZ’s safer-gambling tools include deposit limits, time-outs and self-exclusion, and an exclusion applies across both TAB NZ brands. The free Gambling Helpline is 0800 654 655, with a text line at 8006, and Safer Gambling Aotearoa runs the counselling service. There is no single national online-betting exclusion register; the register the casino law will require is for online casinos only, and it does not extend to sports betting. The protection on the betting side is operator-level, not national, and the only national entry point for help is the helpline and Safer Gambling Aotearoa.

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. The warning is not a rule; it is a statement of the risk a New Zealand bettor accepts when they use an offshore brand.

Responsible gambling, in the New Zealand frame

A bet is a cost, not an investment. The math in the opening sections makes that plain: at a 5% market margin, the average bettor loses 5% of every dollar wagered before any of the other conditions of the offer are priced in. A bettor who bets more than they can afford to lose is not betting — they are paying a subscription to a system that is designed to take their money over the long run.

The right bankroll for a recreational bettor is money set aside for entertainment, sized to what the bettor can write off without it changing the rest of their month. The wrong bankroll is rent money, credit-card float, or borrowed cash; each one of those is a loan a bettor is taking out against an expected loss, and the loan is the part the bettor pays back if the bets do not land.

TAB NZ’s app surfaces the tools the law requires: deposit limits that cap the daily, weekly or monthly inflow, time-outs that pause the account for a set period, and self-exclusion that closes the account for a longer period and applies across both TAB NZ brands. The tools are pre-set in the sense that they are on by default; raising a limit usually takes a cooling-off period, and the bettor who has set the limit and forgotten the password is the bettor the cooling-off period is for.

The free Gambling Helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa are the two national points of contact for a New Zealand bettor who is worried about their own betting or someone else’s. Neither one is a TAB NZ service; both are funded by the problem-gambling levy and the wider harm-minimisation framework. The advertising rules on the bookmaker’s side come from the Advertising Standards Authority’s Gambling Advertising Code, which says ads must not target children (under 14) or young people (14 to under 18) and must not encourage harm — the 25% audience test is the line the ASA uses to decide whether an ad has crossed it. The ASA’s rules apply to lawful New Zealand advertising; offshore brands advertising into New Zealand are outside the ASA’s reach, which is the part of the cost a New Zealand bettor prices in.

A bettor who has decided to stop is supported by self-exclusion at TAB NZ, by a cooling-off period on deposits, and by the helpline if they need a person to talk to. A bettor who has not decided to stop is supported by the same tools in smaller increments — a lower deposit limit, a shorter session, a stake they have written down before they opened the app. The smaller increments are where the work happens, and the helpline is for the day the smaller increments stop being enough.

Bet types and how each one pays

Win is the simplest bet: the runner finishes first, the bet pays at the dividend declared. Place is the bet on a runner finishing in the first two (or three, on a large field) at a reduced dividend. Each Way is two bets in one: a Win bet and a Place bet at equal stake, and the dividend on the Place leg is usually a fraction of the Win dividend. The fraction is set by the number of runners in the race, and the operator’s betting rules are the place to find it.

Quinella is two runners in any order in the first two. Exacta is two runners in the first two in the right order. Trifecta is three runners in the first three in the right order. First Four is four runners in the first four in the right order. Each one of these bets is a single bet against a single dividend, declared at the end of the race, and the size of the dividend depends on the pool of money bet into the race and the number of winning combinations.

Double and Treble are bets on two or three races in sequence: the stake from the first leg rolls into the second, and the stake from the second (if it wins) rolls into the third. Daily Double is the same bet on two specific races of the day. Running Double is a bet on consecutive races. Quaddie is a bet on four specific races, usually the last four of a meeting, with a declared pool dividend. Big6 is the same shape of bet, extended to six races. The order matters, the pools combine, and the dividend is the figure the bettor actually wins.

On sports, the menu is the standard one: head-to-head, line (handicap), total points (over / under), first scorer, half-time result, and the same-game multi combinations. A head-to-head bet is a bet on the result; a line bet is a bet on the result after a handicap is applied; a totals bet is a bet on the combined score. The odds on each are the operator’s, and the margin is folded into every price.

A multi is a bet on multiple legs combined into one price. The price is the product of the legs’ odds. A same-game multi is a multi whose legs all come from one event. The price is the same product, the correlation between legs is the same correlation, and the margin the operator loads on a same-game multi is usually higher than the margin on the equivalent single bets because the correlation is harder for the bettor to price. The headline “build your bet” feature is the operator’s way of selling the same-game multi; the price the bettor sees is the product, and the margin is the cost the headline does not name.

Sports, tournaments and the New Zealand calendar

The sports TAB NZ takes bets on mirror the calendar New Zealanders bet on: rugby union through Super Rugby Pacific and the All Blacks’ test season, rugby league through the NRL and the Warriors, cricket through the Black Caps’ international schedule and the domestic Super Smash, football through the A-League and the international leagues the operator lists, basketball through the NBA and the NBL, and the major US leagues — NFL, MLB, NBA — that the operator offers year-round.

Horse racing runs year-round, with a New Zealand meeting every day of the year and the major Australian carnivals — Melbourne Cup, the Sydney autumn, the Brisbane winter — sitting alongside the New Zealand features. Harness racing runs on the same calendar; greyhound racing is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races. The closing is the operator’s calendar problem, not the bettor’s; the bettor’s calendar problem is the same one it has been: the meetings the operator lists and the dividends the pool declares.

The Cup Day cluster — Melbourne Cup, the New Zealand Cup meeting at Riccarton, the racing carnivals that anchor the spring — is the busiest betting window of the year, and the window where the margin matters most. A bettor who places a multi on the day’s feature races is betting against a margin on every leg, multiplied into a single price, and the cost compounds with every leg added. The bettor who reads the price of each leg separately, places singles on the ones they want and skips the ones they do not, gives up the headline payout of a multi and pays a lower margin in exchange.

Esports sits in a different legal position: the Racing Industry Act 2020 does not establish whether esports betting is “sports betting”, and TAB NZ’s coverage of esports is the only lawful route to an esports bet in New Zealand. The major titles — CS2, League of Legends, Dota 2, Valorant — are the ones every offshore bookmaker also lists, and the price difference is the part a New Zealand bettor is pricing in when they use an offshore brand.

Frequently asked questions

How are horse racing odds paid out?

A Win bet pays the stake multiplied by the dividend declared on the runner. A Place bet pays a reduced dividend, set at a fraction of the Win dividend and determined by the number of runners in the race. An Each Way bet is two bets of equal stake — a Win bet and a Place bet — so the cost is twice the unit stake and the return on a Win is the Win dividend, on a Place is the Place dividend, and on both is the sum. Exotic bets (Quinella, Exacta, Trifecta, First Four, Quaddie, Big6) pay a single dividend declared from the pool of money bet into the race, with the dividend rising as the field of winning combinations narrows.

How is a football multi priced?

The price of a multi is the product of the prices of the legs, with the operator’s margin loaded on every leg. A four-leg multi at 1.80, 1.95, 1.70 and 2.05 multiplies out to about 11.69, and a $10 stake pays $116.90 if all four legs win. The margin sits inside each leg’s price, and the multi’s effective margin is higher than the average of the legs because the compounding amplifies every percentage point. A bettor who values the multi compares the multi price to the equivalent singles at the same stake; if the multi price is lower than the singles combined, the operator has loaded a correlation discount on top of the per-leg margin, and the discount is the bettor’s cost.

How do I bet on horse racing from New Zealand?

TAB NZ is the only operator lawfully taking bets from people in New Zealand on horse racing. The TAB NZ app lists domestic and Australian meetings, with Win, Place, Each Way, the exotics (Quinella, Exacta, Trifecta, First Four, Double, Treble, Quaddie, Big6) and the multi combinations. Account opening requires a verified New Zealand address and ID, and the bettor must be 18 or older. Bets are placed from a TAB NZ account or at a TAB retail outlet, with the dividend the bettor is paid being the one declared at the end of the race.

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

TAB NZ, through its two online brands TAB and Betcha, is the only provider lawfully offering racing and sports betting to people in New Zealand since 28 June 2025, under section 74AAA of the Racing Industry Act 2020. There is no second licence to apply for and no register of approved bookmakers, because there is only one lawful provider. Any other brand a New Zealand bettor sees is taking bets unlawfully under New Zealand law, and the Department of Internal Affairs has told providers serving New Zealand to withdraw.

What does a winning bet pay back?

A winning single returns the stake multiplied by the decimal odds. A $10 bet at 2.10 pays $21 back, with $11 of that being the net profit once the stake is returned. A multi pays the stake multiplied by the product of the legs’ odds, with the stake lost if any leg loses. A free bet pays the profit only — the stake is usually not returned, so a $50 free bet at 3.00 pays $100 in profit, not $150.

What is a bookmaker’s margin?

The margin is the share of every dollar wagered that the bookmaker keeps, calculated as the overround (the sum of the implied probabilities minus one) divided by that sum. A two-way market priced at 1.90 / 1.90 has implied probabilities of 52.63% on each side, summing to 105.26%; the overround is 5.26%, and the margin is 5.0%. The margin is invisible on the bet slip; it is folded into every price the bookmaker writes, and a sharper market carries a thinner margin than a softer one.
