Are Lotto and Gambling Winnings Taxed in New Zealand?

No — if you win Lotto, Powerball, Strike or a casino jackpot in New Zealand, the prize is paid to you in full, with no tax taken off the top. New Zealand does not treat gambling winnings as income, so there is no “lottery tax” or “winnings tax” on the person who wins. What can be taxed is what you do next: the interest, dividends or rent the money earns once it is saved or invested.

Are Lotto and Powerball winnings taxed in New Zealand?

Lotto and Powerball prize money is not taxed in New Zealand. When you win, Lotto NZ pays out the advertised amount as a single tax-free lump sum straight into your bank account — there is no withholding, no prize-tax form and nothing to declare on the win itself. The same applies across the Lotteries Commission’s games, including Strike, Keno, Bullseye and Instant Kiwi scratch tickets.

This is why a $20 million Powerball jackpot pays $20 million, not a reduced “after-tax” figure. If you want to understand the games behind the headlines, our guide to playing New Zealand Lotto online and the companion explainer on how to play Powerball cover the draws, divisions and odds in detail.

Why New Zealand does not tax gambling winnings

New Zealand income tax applies to income, and a one-off windfall from chance is not treated as income. A Lotto prize or a lucky night at the tables is a stroke of fortune, not a salary, a business profit or a return on an investment, so it is not taxed in the ordinary player’s hands. That is why a Lotto winner keeps the full prize, with no tax taken off the top.

It cuts both ways. Because winnings are not income, your gambling losses are not deductible either — you cannot offset a losing year at the pokies against your salary or any other taxable income. The system simply leaves recreational gambling outside the tax net.

Are casino, pokie, TAB and online gambling winnings taxed?

Casino, pokie and sports-betting winnings are tax-free for recreational players, exactly like a Lotto prize. The rule is about the nature of the win, not the game: a jackpot on a gaming machine, a blackjack streak or a correct bet on the rugby is a windfall, so there is no income tax to pay on the amount you take home.

Online and offshore casino winnings

Winnings from online casinos are treated the same way, whether the site is based in New Zealand or offshore. The place you play does not change the fact that, for a casual player, the money you win is not taxable income here. New Zealand’s regulation of online casinos changed with the Online Casino Gambling Act 2026 and the move to licensed operators, but that framework governs how operators may advertise and run their sites — it does not introduce a personal tax on players’ winnings. Deposit mechanics such as $1 deposit casinos and bonus terms sit separately from tax; a bonus is a marketing feature, not taxable income.

Sports betting and the TAB

Betting profits are not taxed for the punter either. Whether you back a horse or a football result through TAB New Zealand, the money you collect is a gambling windfall rather than income, so you keep all of it. The operator, not you, carries the tax and levy cost on betting profits.

When gambling winnings can become taxable

There are a few situations where tax does enter the picture. The prize itself stays tax-free, but what happens around it can be taxable.

Interest, dividends and investment income after the win

The moment your winnings start earning a return, that return is taxable. Leave $1 million in a term deposit and the interest it pays is taxed; put it into shares and the dividends are taxed; buy a rental and the rent is taxed. Banks deduct resident withholding tax (RWT) from interest and dividends automatically, so you need to give them your IRD number and choose an RWT rate that matches your income band — the personal income tax rates run from 10.5% up to 39%. This ongoing investment income, not the prize, is what the tax system is interested in.

Running gambling as a business

The main exception is a person who gambles as a business rather than for recreation. Where betting is organised, systematic and carried on as a livelihood rather than for fun, the profits can take on the character of business income and become taxable, with losses deductible against them. This is a high bar that very few people cross; a hobby player who gambles often is still a recreational gambler, not a business.

Overseas lotteries and non-residents

A New Zealand tax resident is taxed on their worldwide income, so any interest or other income you earn after an overseas win is taxable here — even if the other country has already deducted tax, though you may be able to claim a foreign tax credit for it. The prize windfall itself follows the same principle as a domestic win, because a one-off gambling win is not income. In practice, many foreign lotteries withhold their own tax before paying out, so an advertised overseas jackpot can arrive smaller than the headline figure, and if you are tax resident in another country that country’s rules may also apply. Large cross-border wins are worth checking with a tax adviser.

Prize money from competitions and sponsorship

Not every “prize” is a gambling windfall. Prize money connected to your work, a sponsorship deal or a professional competition can count as income because it is tied to an activity you carry on for reward. That is a different category from a Lotto ticket or a spin of the reels, and it is taxed on its own facts.

Who actually pays tax on gambling in New Zealand?

Tax on gambling is collected from operators, not winners. The business that runs the game pays duty and levies on the money that flows through it, which is one reason the player keeps the full prize. Lotto NZ pays lottery duty of 5.5% on the nominal value of all tickets in a game, and every gambling operator pays a problem gambling levy on its profits, with the rates set by Order in Council. The table below shows who pays what.

None of these costs are charged to you as a winner. They are the operator’s cost of doing business, and the levy money helps fund problem-gambling services.

What a winner should actually do about tax

The prize needs no tax action, but the money it earns does. A short checklist keeps you on the right side of IRD.

• Give your bank your IRD number and set the right RWT rate. If the bank does not hold your IRD number, interest can be taxed at a no-notification rate of 45%, which is higher than almost anyone’s correct rate.
• Match your RWT rate to your income. Pick a rate too low and you face a bill at year-end; too high and you lend IRD money for free. A large lump sum can push your investment income into a higher band.
• Declare ongoing investment income. Interest, dividends and rent from the winnings are taxable and should appear in your tax return, even though the win itself is not.
• Tell Work and Income if you receive a benefit. A one-off windfall and any income it later earns can affect income-tested assistance such as a benefit or the Accommodation Supplement.

Can you give winnings to family tax-free?

Yes — gifting winnings is tax-free in New Zealand. Gift duty was abolished for gifts made on or after 1 October 2011, so you can share a Lotto or casino win with family or friends without a gift tax. A gift is generally not taxable income in the recipient’s hands either, because it is given out of affection rather than as payment. The practical points to watch are not about tax: large gifts can interact with things like residential-care subsidy rules and relationship-property arrangements.

Frequently asked questions

Do I have to pay tax when I win Lotto in New Zealand?

No. Lotto, Powerball, Strike and other Lotteries Commission prizes are paid to you tax-free as a lump sum. You only pay tax later on income the money earns, such as interest in a bank account.

Do I need to tell IRD if I win the lottery?

You do not need to declare the win itself, because it is not taxable income. You should, however, give your bank your IRD number and declare any interest, dividends or rent you earn after investing the money, and tell Work and Income if you receive an income-tested benefit.

Are online casino winnings taxed in New Zealand?

No, for a recreational player online casino winnings are treated the same as any other gambling windfall and are tax-free. Where you play does not change this; only income earned on the money afterwards is taxable.

Are professional gamblers taxed on their winnings?

They can be. If gambling is carried on as an organised business to earn a living, the profits can be taxable and losses deductible. This is a high threshold that ordinary frequent players do not meet.

Is a foreign lottery win taxed in New Zealand?

A genuine overseas gambling windfall is generally not taxed as income in New Zealand, but the country running the lottery may withhold its own tax before paying out, and other rules can apply if you are tax resident elsewhere. Large cross-border wins are worth checking with a tax adviser.
