The New Zealand betting market is not like most. Since the Racing Industry Amendment Act 2025 took effect on 28 June 2025, one operator — TAB NZ — may lawfully take racing and sports bets from people in New Zealand, and it does so under two online brands. That fact alone reshapes everything else on this page: there is no register of licensed bookmakers to consult, no second application to compare, and no alternative regulator keeping a parallel watch over what the NBA pages show. The choice that exists is the choice between TAB and Betcha (the same bookmaker behind two product names), and the choice outside it.

This page maps that territory. It names the two lawful brands and what each brings, lays out how NBA odds and spreads are built so a reader can read them, follows the league’s own season structure from opening tip to Finals, and checks what every other brand a New Zealand punter will encounter actually is — and is not. The voice throughout is sceptical of marketing and patient with arithmetic, because the difference between a 1.91 line and a 1.95 line is the difference between a market that holds its margin cleanly and one a bettor quietly pays through.

How the Two Lawful New Zealand Brands Compare

The two brands run by TAB NZ appear as rivals in a store window. They are not. TAB NZ is the statutory monopoly holder established under the Racing Industry Act 2020; TAB and Betcha are its two product surfaces, operated in partnership with Entain New Zealand under a 25-year agreement signed in 2023. Comparing them across a betting comparison table is misleading on its face — the order fills out below not to rank them against each other, but to show what each brand keeps and what it doesn’t.

The table is honest on a point most comparison pages fudge. Every brand below the two TAB NZ rows has no entitlement to take a New Zealand customer’s money. The bookmakers know this; some have already adjusted. A reader who lands on them anyway meets no domestic complaint route, no deposit-limit tool anchored to a New Zealand harm-minimisation framework and no recourse if a withdrawal stalls. Each row of the offshore section is presented for identification because New Zealand punters encounter these brands in search results and on social media — naming them serves identification, not endorsement.

Within the two lawful brands, the practical difference is interface. TAB is the legacy product: a wider market menu, deeper racing coverage, multi-leg multis and Same Game Multis, deposit limits tied into TAB NZ’s account-level self-exclusion that spans both brands, and the safer-gambling tools (deposit limits, time-outs, self-exclusion) available through the in-app settings. Betcha is the newer, lighter surface: the same feed, less clutter, a bet slip built for quick-fire punting on phones. A punter who keeps a racing book and a multis book lives on TAB; a punter who mostly wants to drop a Same Game Multi on an NBA game in three taps lives on Betcha.

What TAB NZ Actually Is, and Why It Is the Whole Market

TAB NZ sits at the centre of New Zealand betting because the Racing Industry Act 2020 made it the centre. The Racing Industry Amendment Act 2025 inserted section 74AAA: 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 provision took effect on 28 June 2025, and the Department of Internal Affairs (DIA) told unlicensed providers to withdraw with immediate effect.

The structure that makes the monopoly work is the Entain partnership. Entain runs the TAB business under a 25-year agreement signed in 2023, taking a 50/50 share of gross profits with at least $150 million a year going to TAB NZ for the first five years, and pledged a one-off $100 million payment to the racing sector. The technology, the trading desk, the app, the Betcha surface — most of the operational side lives with Entain; the statutory authority stays with TAB NZ.

What that means in plain terms: a New Zealand punter’s lawful NBA bet goes through one trading operation, one margin policy, one account that crosses both brands, and one harm-minimisation framework. There is no competing bookmaker offering a sharper price on the same NBA game from a New Zealand IP. The price for “Celtics -4.5” on Tuesday is the price TAB NZ publishes on Tuesday, on both its apps. If the price looks generous, the reason is that TAB NZ priced it that way; if it looks stingy, the reason is the same.

The boundary the law draws is wide. Section 74AAA covers racing and sports betting from any operator, anywhere in the world, to a person in New Zealand. The Online Casino Gambling Act 2026 licenses online casino gambling only — TAB NZ’s success in applying for a casino permit does not extend the betting monopoly. Greyhound racing closes in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either. The ban covers events held inside and outside New Zealand; a wager on the NBA Finals in Auckland is treated the same as a wager on the NBA Finals in Boston.

The legal target is the operator, not the player. Section 19(4) of the Gambling Act 2003, inserted in 2025, states that an individual may not be convicted for placing a bet with an offshore betting operator in breach of section 74AAA. No published penalty for a New Zealand player betting offshore was found. DIA warns that offshore operators may not return unspent credits, may not pay out large wins and are often in jurisdictions with minimal consumer safeguards. The geometry is honest: illegal for the offshore operator to serve the country, no domestic backstop for the player who uses one.

The Self-Exclusion and Safer-Gambling Frame Around New Zealand NBA Betting

Help exists, and it costs the punter nothing to use it. TAB NZ’s app exposes deposit limits, time-outs and self-exclusion in the account settings, and an exclusion spans both TAB and Betcha because both sit on the same TAB NZ account. The free Gambling Helpline is 0800 654 655; the text line is 8006. Safer Gambling Aotearoa runs structured support services, and the Problem Gambling Levy (0.74%, in force from 1 July 2025 to 30 June 2028) funds much of the harm-minimisation work.

TAB NZ’s age gate is 18+. The app carries a 17+ App Store age rating and explicitly states that customers must be 18 or over to bet. The land-based casino age is 20 — a separate rule that does not bleed into sports betting. A New Zealand punter opening a TAB NZ account needs a verified New Zealand address and ID; offshore operators do not require either, and DIA names that absence as part of the risk profile for the customer using them.

There is no single national online-betting self-exclusion register in New Zealand. The register that the 2026 online casino law introduces is for online casinos only. A punter who wants to step back from NBA betting on TAB NZ sets the limit through TAB NZ’s own app; a punter who has used multiple offshore brands has to close each account separately. Self-exclusion works better through one provider than through ten, and this is one place the monopoly quietly serves the punter.

How to Read an NBA Line — Margins, Spreads, and What the Odds Actually Say

An NBA game opens with a market and a margin. The market is which side bets go on; the margin is what the bookmaker keeps of every dollar that lands on it. The standard two-way market — who wins straight up — is the cleanest case to read, and it is the one a punter meets first when an NBA game tips off.

Decimal odds are the format. TAB NZ writes prices in decimal form: a $10 bet at $1.90 returns $19 if it wins (a $9 profit on the $10 stake), a $10 bet at $1.50 returns $15 ($5 profit). Fractional odds are converted to decimals behind the counter; the maths is identical and the format here stays decimal throughout.

The margin sits inside the price. Take a balanced NBA Finals game priced at $1.90 / $1.90. A punter staking $10 on each side puts $20 in; one side wins and pays $19; the bookmaker keeps $1. Bookmaker’s margin on this market is calculated by converting the prices to implied probabilities (1/odds): the implied probability of $1.90 is 1/1.90 = 0.5263, or about 52.63%. Summing the two sides gives 1.0526 (an overround of 5.26%). The margin is then 1 minus the payout share (where the payout share is 1 divided by the sum of implied probabilities), which is 1 – (1/1.0526) = 0.05, or 5.0% — roughly five cents in the dollar of stakes kept by the bookmaker across the market.

The illustrative case lands on a 5–6% margin band for a balanced two-way NBA line. Real NBA prices in well-off matches hover near that figure; lopsided matches (a heavy favourite at $1.10 against an underdog at $7.50, say) carry different margins again because the implied probabilities are not symmetric. The only honest reading of “what does the bookmaker keep” on a market line is to add the implied probabilities, subtract from 100% and treat the gap as the margin. That is the move the rest of this section uses whenever a price appears.

The market margin shows up in every market a punter touches, not only the head-to-head. Totals (over/under the combined score), handicaps (point spreads), player props (LeBron over 27.5 points), and same-game multis each carry their own margin. A Same Game Multi that pays $5.00 for three legs is expected, at fair prices, to pay roughly $6.50 — the difference is the bookmaker’s cut on the combination bet. The wider the multi, the heavier that cut tends to be, because each leg carries its own margin and the legs compound.

The punter’s working habit is simple. Convert each price to an implied probability (1/odds). Add the implied probabilities on every outcome of a market. Subtract from 100%. The remainder is the margin. Below 3% is exceptional on an NBA match; 4–6% is normal; above 8% is the moment a punter needs to ask whether the bookmaker’s risk model is mispricing something or the line is simply uncompetitive. The arithmetic is one short division per outcome, and it never lies about what the price costs.

The NBA as a League: What a New Zealand Punter Is Betting On

The NBA is thirty teams, twenty-nine in the United States and one in Canada (the Toronto Raptors). Each franchise plays 82 regular-season games, with the season running from late October through April and the playoffs extending into June. The two-conference structure (East and West) seeds sixteen teams — eight per side — into a four-round knockout that ends in the Finals, played as a best-of-seven series.

The 2026 NBA Finals ran from 3 June through 13 June 2026. The New York Knicks won the series 4–1 against the San Antonio Spurs, clinching with a 94–90 Game 5 win on 13 June 2026. Jalen Brunson took the Finals MVP. The 2025 NBA Finals went the other way: the Oklahoma City Thunder beat the Indiana Pacers in seven games, a longer series the year before. The Boston Celtics hold the all-time championship record, with eighteen titles to their name — the first franchise any new punter learns, because the league’s history is essentially a conversation between the Celtics, the Lakers and everybody else.

The league was founded as the Basketball Association of America in 1946 and took its current name through a merger on 3 August 1949. That 1946 date is the only one a punter needs to know for context; everything else is the season structure. From the punter’s chair, the season has five stages: pre-season (October), regular season (late October to early April), the play-in tournament (mid-April, six teams, two extra playoff spots per conference), the playoffs proper (April to June), and the off-season (summer). Each stage has its own bet types — futures early, head-to-head and totals mid-season, player props heavy all year.

The season a New Zealand punter follows in front of the market is the 2026/27 NBA season, beginning October 2026 and running through the 2027 Finals in June. Outright markets (championship, conference finals, division winners, regular-season wins totals) are the earliest products to price up. Same-game multis peak as the playoffs arrive. Player props — points, rebounds, assists, three-pointers, double-doubles — carry through the full calendar.

What NBA Markets Look Like on a TAB NZ Slip

The standard TAB NZ NBA card breaks into several categories, and a punter who understands the categories reads the card faster than one who doesn’t.

Head-to-head (win) is the simplest: who wins the game. Priced two-way, with overtime included — a price at the end of four quarters stands even if the game goes to overtime. Spreads (handicap, line betting) ask whether a favourite wins by more than a set margin or an underdog keeps it closer than a set margin. A Celtics -6.5 line means Boston must win by 7 or more for the bet to cash; the underdog bet wins if Boston wins by 6 or fewer, or if the underdog wins outright. Half-point lines (.5) remove the push (tie) outcome and settle the bet one way or the other.

Totals ask whether the combined score finishes over or under a line — TAB NZ’s standard NBA total sits in the 220–235 range depending on pace. Player props cover individual statistical lines: a LeBron James points line over/under 27.5, a Jayson Tatum rebounds line over/under 8.5, a Stephen Curry three-pointers line over/under 4.5. Same Game Multis (SGMs) let the punter combine legs from the same game — Celtics win, Tatum over 28.5 points, game total over 224.5 — into one betslip with multiplied odds.

Futures run ahead of the schedule. Championship winner, conference winner, division winner, regular-season wins totals, player awards (MVP, Rookie of the Year, Defensive Player of the Year), Finals MVP, and series correct-score markets all price up months in advance. The 2026 NBA Finals MVP futures closed with Jalen Brunson at short odds by tipoff of the series; the 2027 markets are forming now.

Live (in-play) markets update as the game progresses. TAB NZ lists live betting in its apps, with prices tightening and loosening on every possession. The hard rule on live betting is that the bet locks at the price displayed at the time of placement; subsequent price moves don’t retroactively change the bet. No statutory restriction specifically targets NBA in-play markets, and TAB NZ’s in-play product is the same one the punter uses for racing and other sports.

The promo frame around the markets is narrower than most international bookmakers. TAB NZ runs “bonus bets” promotions; the size, wagering terms and qualifying bets are set by TAB NZ’s own published rules, and no New Zealand statute caps those terms. The ceiling a punter cares about is TAB NZ’s published terms on its promotion page, not a regulator’s ceiling — there isn’t one.

The Offshore Brands a New Zealand Punter Will See — and Why Each Carries Caveats

The ten brands below the table exist because search engines surface them and affiliate networks in Europe, Curaçao and Canada push them at New Zealand traffic. None holds a New Zealand entitlement; none is reached by New Zealand harm-minimisation rules; none submits to the Department of Internal Affairs for compliance. Each is described here in the format the table set out: name, status, what the brand itself publishes on the subject the punter cares about.

Alawin runs a sportsbook covering basketball alongside football, tennis, table tennis, ice hockey, American football and baseball, with live betting, Virtual Sports and esports also offered. No New Zealand entitlement. A punter meeting Alawin in search results must read the absence of a New Zealand licence as the headline: every other feature the brand promotes is built on a licence that gives the brand no right to take a New Zealand customer’s bet.

RTbet is a Curaçao-licensed bookmaker whose sportsbook covers basketball alongside football, tennis, table tennis, ice hockey, American football and baseball, with live betting and virtual sports available. The Curaçao licence is the standard offshore setup — it authorises the brand to take bets from jurisdictions whose own rules allow it, and New Zealand’s rules do not.

Roobet holds a Curaçao licence (OGL/2024/687/0427), held by Raw Entertainment B.V., and runs a sportsbook covering basketball alongside soccer, tennis, esports, baseball, ice hockey, MMA and table tennis, with the brand’s terms requiring players to be 18 or older. The 18+ cutoff matches TAB NZ’s, but the rest does not — the licence entitles the brand to operate in Curaçao and selected jurisdictions, and New Zealand is not among them.

Thunderpick is esports-first under a Curaçao licence (OGL/2024/677/0722), held by Paloma Media B.V., and its sportsbook offers a cash-out feature with markets from the Champions League to the NFL. Cash-out is the headline: it lets a punter close a position before the event settles, locking in a smaller win or a smaller loss. The feature is common across offshore books and rare or differently priced on TAB NZ — a point on which an offshore book can look superficially attractive.

RoyalistPlay holds a Tobique Gaming Commission e-gaming licence (No. 0000002), held by Novatrix SRL, and runs a sportsbook offering live betting, sports promotions, results and a schedule, with basketball among the top sports listed. The Tobique licence is one a growing number of offshore operators carry after Curaçao’s reforms; it authorises the brand in its issuing jurisdiction, not in New Zealand.

Sportaza is an Anjouan-licensed bookmaker (ALSI-202606064-FI2) offering cash out before settlement, a Bet Builder where one void leg voids the whole slip, multiples, Asian lines and interval markets in 1, 5, 10 or 15 minute ranges. The Asian lines are the technical draw: they are quarter-point and half-point handicaps that remove the push and rebalance underdog prices. TAB NZ does not run Asian lines, which is one reason an offshore book appears in niche searches.

Spinbara advertises a first deposit bonus of 100% up to EUR 100 and a sport crypto welcome bonus of 100% up to 200 USDT on its English site, alongside a casino welcome bonus of 100% up to EUR 500 plus 200 free spins. The crypto welcome is the unusual feature here — the brand accepts crypto and pays a bonus in USDT. None of this changes the New Zealand status: no entitlement, no domestic consumer backstop.

FunBet is an offshore bookmaker whose sportsbook covers basketball alongside football, ice hockey, American football, volleyball, tennis, rugby and baseball, with live betting and a 24/7 operation. The 24/7 framing suggests a customer-service operation that follows its customers’ time zone, which for an offshore book serving Europe is sensible and for a New Zealand punter at 3 a.m. is incidentally helpful.

LunuBet is an additional operator outside the ten, running casino, live casino, jackpots and sports under one account and accepting customers aged 18 and over only. The account structure — casino and sportsbook under one — is a typical offshore layout and TAB NZ’s structure is the opposite: TAB NZ is sports-only, with no online casino product (the upcoming Online Casino Gambling Act 2026 licence will be a separate product line entirely).

For each of these brands, the practical advice is consistent. A New Zealand punter who decides to use one does so without a domestic regulator’s backstop on payout disputes, without a self-exclusion register that spans New Zealand operators, and without access to TAB NZ’s deposit-limit and time-out tools. If the punter sets a deposit limit at TAB NZ and also opens an offshore account, the limit protects only the TAB NZ balance; the offshore account runs on whatever ceiling the offshore brand sets, which may be higher or may not exist. The Responsible Gambling frame is built around TAB NZ’s account; everything outside it has to be self-policed.

Reading the Bookmaker’s Margin on a Live NBA Market

The single most useful number a punter can compute before placing a bet is the bookmaker’s margin on the market they are about to enter. Below is the arithmetic worked once in full, in the format that the rest of the page uses whenever an NBA price is on the screen.

The illustrative two-way market is priced at decimal odds of 1.90 / 1.90. The implied probability of each outcome is 1 divided by 1.90, which equals 0.5263157… The sum of the two implied probabilities is 1.0526315…, or about 105.26%. The payout share — the share of every dollar staked that the bookmaker returns to winning punters in the long run — is 100% divided by 105.26%, which equals about 0.9500, or 95.00%. The bookmaker’s margin is 100% minus 95.00%, which equals 5.00% — exactly five cents in the dollar kept by the bookmaker across the market.

That 5.00% margin is a band, not a single number. Different NBA markets hold different margins: lopsided head-to-heads typically carry higher margins than balanced ones (the favourite-underdog split lets the bookmaker protect both sides), totals and handicaps usually sit in a 4–6% band, player props can run higher because the data inputs are smaller, and Same Game Multis compound leg-by-leg margins and frequently land above 8%. The arithmetic — implied probability sum, payout share, margin — is identical for each; only the inputs change.

The punter’s takeaway is plain. A bookmaker who prices a market at 95% payout (5% margin) keeps five cents of every dollar wagered. A bookmaker who prices at 90% payout (10% margin) keeps ten cents of every dollar. Over a season of NBA betting, that 5% gap is the difference between a punter who holds their bankroll roughly flat (because the bookmaker’s edge is roughly what the punter’s edge is not) and a punter who bleeds it steadily (because the bookmaker is taking ten cents of every dollar in play). The line a punter reads is the line the bookmaker writes; the margin is what it costs to bet on it.

The NBA Season in New Zealand Time

The NBA’s east-coast tip times push most regular-season games into a New Zealand morning slot the next day. A 7:30 p.m. Eastern tipoff is 11:30 a.m. New Zealand time while in Eastern Standard Time (late October to early November, then early March to early April); while in Eastern Daylight Time (mid-November to early March), a 7:30 p.m. tipoff lands at 12:30 p.m. the next day in New Zealand. Late games (10:00 p.m. Eastern) push to 2:00 p.m. or 3:00 p.m. the next day.

The schedule matters because TAB NZ’s live markets update as the game runs. A punter betting on an NBA game needs to know whether they are looking at the pre-match price (the one printed at tipoff) or the live price (the one updated mid-game). The lock on a pre-match bet is tipoff; subsequent price moves do not change the bet. Same Game Multis must be placed before tipoff; live SGMs are a separate product where they exist. The punter’s habit is to check the clock against the time zone before treating a price as the “live” price.

The Choices a New Zealand NBA Punter Actually Faces

Stripped of marketing and offshore noise, the choices reduce to three.

Choice one: TAB or Betcha, with the difference being interface rather than price or market. A punter who values the racing-and-sports integration and the wider product menu lives on TAB; a punter who wants a faster bet slip and a phone-first surface lives on Betcha. The two sit on the same TAB NZ account, and a self-exclusion on one is a self-exclusion on both.

Choice two: how much of the bankroll to leave TAB NZ for, given that any other brand a New Zealand punter uses is unlicensed in New Zealand and trades the regulator’s protection for a price. There are reasons to consider one — a market TAB NZ doesn’t carry (Asian lines on the spread are the cleanest example), a feature TAB NZ doesn’t run (cash-out at full granularity), a bonus structure outside TAB NZ’s terms — and each carries the caveats the previous sections laid out.

Choice three: the within-app pattern. A punter’s NBA betting on TAB NZ sits across outright markets (championship, conference, MVP), regular-season markets (head-to-head, spread, total, player props), live markets (in-play updates), and Same Game Multis. The same tools that work on a single NBA game — checking implied probability, adding sides, computing the margin — apply across each. The numbers are cheap to compute, and a punter who does them once a week will read a card faster than one who trusts the marketing.

What the Off-Terms Are — and Why They Matter

Two clauses appear on most TAB NZ bonus bet offers and most offshore welcome packages, and they shape what an offer is actually worth.

The minimum price for a qualifying bet is the first. TAB NZ’s bonus bet terms require each qualifying bet to be placed at odds at or above a stated threshold — typically $1.50 or $1.80, depending on the promotion. Bets placed below the threshold do not count toward turnover. The clause exists because low-price bets (heavy favourites at $1.05, say) carry a margin too thin to make a “wagered this much” requirement mean anything. A punter reading the terms knows that the wagering path must stay on prices that actually carry risk.

The expiry on bonus bets and free spins is the second. TAB NZ’s bonus bets carry an expiry window measured in days; offshore bonuses carry windows measured in days or weeks. A punter who lets the window lapse loses the bonus and the qualifying work behind it. Reading the date is the cheapest move available in this market.

A third clause that recurs offshore is the cap on free-bet winnings: a “free bet up to $100” that pays out at most, say, $500 in winnings even on a winning multi. The marketing name is “free bet”; the actual product is a capped wager with no stake returned. The free-bet value formula for a free bet whose stake is not paid back is the free-bet amount multiplied by (odds minus 1) divided by odds, then multiplied by the market’s payout share — which is the market’s expected return net of margin. The arithmetic says a $100 free bet at $5.00 odds is worth $80 multiplied by the payout share, typically in the $65–75 range across NBA markets. A punter who treats the bonus as cash loses the gap between the marketing name and the cap.

How a Winning NBA Bet Pays Out

The return on a winning NBA bet is the stake multiplied by the decimal odds; the net profit is the stake multiplied by the odds minus 1. A $50 bet at $2.40 returns $120 ($50 stake × 2.40 odds = $120 total return; $120 minus $50 stake = $70 profit). The same $50 on a Same Game Multi of three legs paying $5.00 returns $250 ($50 × 5.00 = $250, $200 profit). The formula is the same, and it holds for any winning NBA bet on TAB NZ or any other licensed bookmaker.

The “what does a winning bet pay” reading is the cleanest version of the maths a punter will meet. The “how likely is it to win” reading is a separate question, and the margin already paid the answer — over a season, the bookmaker keeps 5–6% of every dollar staked across a balanced market. The punter’s expected value on any single bet is the implied probability the market prices in, minus the bookmaker’s margin. The punter who finds +EV bets exists, but he exists in the gap between markets, not in the markets themselves.

Responsible Gambling in Practice for an NBA Punter

The harm-minimisation frame on TAB NZ is built into the account. A punter opens TAB or Betcha, verifies age and address, then configures deposit limits in the account settings. The limits apply across both brands because both share the TAB NZ account. Time-outs (24 hours to several weeks) pause betting without closing the account. Self-exclusion closes the account for a chosen period — six months, one year, five years.

Offshore brands carry the same configurations internally, but they are not anchored to a regulator who monitors them, and there is no consistent standard across the ten brands. A punter who limits their deposit on TAB NZ to $200 a week holds that limit on TAB NZ; an offshore account, opened alongside, can hold a $2,000 ceiling the punter never set. The Responsible Gambling frame is one account on one operator; closing every other account is the punter’s responsibility.

DIA’s published harm-minimisation expectation is that operators track deposit patterns, identify escalation, and intervene. TAB NZ’s structured tools — deposit limits, time-outs, self-exclusion — are how it meets that expectation. The Offshore brands’ interventions (where they exist) are operator policy, not regulator-mandated, and the punter who escalates a dispute through an offshore brand meets the offshore brand’s own complaints process.

Outside the operator frame, the helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa offer free, confidential support. The helpline covers all forms of gambling harm in New Zealand and is the first call any punter needs to make if betting stops being fun. None of these tools requires a punter to stop betting first; they exist to be set up before a problem starts.

Frequently Asked Questions

Can NBA players bet on other sports?

The NBA’s own rules prohibit NBA players from betting on any sport — including non-NBA events — while employed by an NBA franchise. The rule covers coaches, referees and team staff as well. The question typically arises because the NBA’s gambling-policy enforcement has produced several high-profile suspensions and bans in recent seasons. A New Zealand punter reading the news and asking whether players can bet on football, tennis or horse racing is asking about a different question: whether the player is allowed to place any bet at all, the answer to which is no.

How do second-half bets work in the NBA?

A second-half bet is a bet on the score from the start of the third quarter to the end of the game. The score at halftime carries over as the line; an “over 110.5 second-half points” bet wins if the combined second-half score (both teams) exceeds 110.5. Second-half lines reset with zero score at the start of the third quarter and do not include the first-half result. TAB NZ’s NBA card lists second-half lines alongside the full-game lines, and the same odds apply to both. A punter with a feel for pace and game flow can use second-half markets to express a view on a tighter game.

How does a punter bet on the NBA?

The basic NBA bet is the head-to-head (who wins the game, including overtime). A punter logs into TAB or Betcha, opens the NBA section, selects the game, chooses the side, enters a stake and confirms the bet. Spreads (handicap), totals (over/under), player props and Same Game Multis all sit on the same slip and follow the same flow. The pre-match price locks at confirmation; live markets update in real time and lock at the price displayed at the moment of placement. A punter’s first bet is ten minutes in the app, and there is no minimum stake above what TAB NZ’s terms require.

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

TAB NZ is the only lawful provider of online sports and racing betting in New Zealand under section 74AAA of the Racing Industry Act 2020, in force since 28 June 2025. TAB NZ operates two online brands — TAB and Betcha — through its partnership with Entain New Zealand. No other bookmaker holds a New Zealand licence, and no licensing route exists for one. The Department of Internal Affairs told unlicensed providers to withdraw from New Zealand with immediate effect. A New Zealand punter who wants a legal, regulator-supervised, harm-minimised betting environment uses TAB or Betcha.

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

The total return on a winning bet is the stake multiplied by the decimal odds. The net profit is the stake multiplied by (odds minus 1). A $100 bet at $1.50 returns $150 ($50 profit). A $100 bet at $3.00 returns $300 ($200 profit). Same Game Multis combine multiple legs, with each leg’s odds multiplied into the next, so a three-leg SGM at legs priced $1.80, $1.90 and $1.70 combines to about $5.81, and a $50 bet at that price returns $290.50. The arithmetic is the same on every market and bookmaker.

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

The margin is the share of every dollar staked that the bookmaker keeps across a market. It is calculated by converting each outcome’s decimal odds to an implied probability (1 divided by odds), adding those probabilities together, and taking the difference from 100% after accounting for the payout. An NBA game priced at 1.90 / 1.90 has implied probabilities of 52.63% each, summing to 105.26%; this 105.26% sum is the overround. The bookmaker’s margin is calculated by dividing 1 by the sum of implied probabilities (1 / 1.0526 = 0.95), which leaves 5% (1 – 0.95) as the bookmaker’s margin. The market pays back 95% to winning punters in the long run. Margins of 4–6% are typical on balanced NBA markets; same-game multis and player props often run higher. A punter checking the margin before placing a bet can see the price the bookmaker is charging for the wager.
