A Lotto prize, a pokies win in a casino and a payout from an online casino are treated the same way by New Zealand tax law in most cases: the win itself is not taxed. Tax shows up later, on the interest the money earns, and in a few situations on the winnings themselves. At Lucky Elf we've put the rules, the exceptions and two practical checklists in one place.
Do you pay tax on gambling winnings in NZ?
For recreational players, no. New Zealand, like Australia and Canada, does not generally tax gambling winnings. The exception is winnings that come from running gambling as a business.
This applies to New Zealand tax residents. People who are tax resident in another country may owe tax there, so their position needs checking separately.
Lotto prizes
Lotto, Powerball and Strike prizes are paid without any tax deducted. A Division 1 win of several million NZD arrives in full.
The odds behind those prizes:
• Lotto Division 1: 1 in 3,838,380
• Powerball jackpot (six Lotto numbers plus the Powerball): 1 in 38,383,800
Prizes have to be claimed within 12 months of the draw.
Casino and online casino wins
The same rule covers land-based casinos, pub pokies and online casino play. A recreational win is not income, so there's nothing to declare on it. This doesn't depend on the size of the win or on whether the money came from a slot, a table game or a jackpot.
When winnings become taxable
Inland Revenue can treat winnings as income when gambling works like a business. Courts in New Zealand, Australia and the UK look at similar signs:
• the activity is systematic and organised, with records, budgets and a plan
• it's done regularly and at a scale that looks like a trade
• skill plays a real part in the outcome, rather than pure chance
• the person relies on it as a main source of income
Most of these point to betting or poker played at a professional level. Spinning slots for entertainment doesn't meet them, because results come from a random number generator. If your situation sits anywhere near the line, an accountant or Inland Revenue can confirm how it's treated.
Where tax does apply after a win
A tax-free prize stops being tax-free once it starts earning. Interest from a term deposit or savings account is taxable income, and so are returns from shares or property bought with the winnings.
Banks deduct resident withholding tax from interest. If your RWT rate is set too low, the difference is payable at the end of the tax year. Updating the rate with your bank right after a large deposit avoids a surprise bill.
Giving part of a win to family is simpler. New Zealand has no gift duty, so the gift itself is not taxed. Any interest the recipient earns on it is taxable for them.
Taxes the operators pay
Tax on gambling in New Zealand is collected from operators, not players. These are the duties administered by Inland Revenue:
| Duty | Who pays it | What it’s charged on |
|---|---|---|
| Casino duty | Casino operators | Gambling profits |
| Gaming machine duty | Gaming machine operators | Gaming machine profits |
| Lottery duty | Lottery operators | Nominal value of all tickets |
| Totalisator duty | Betting operators | Racing and sports betting |
| Problem gambling levy | Gambling operators | Gambling profits |
| Online gambling duty | Overseas online operators | 12% of profits from NZ residents |
The online gambling duty started on 1 July 2024 as the offshore gambling duty. Profits for this duty mean the money received from New Zealand residents minus the prizes paid back to them. Operators supplying more than NZD 60,000 a year to New Zealand residents also register for GST. None of these duties are taken from a player's winnings.
Checklist: after a big win
☐ Confirm you are a New Zealand tax resident
☐ Save the payout confirmation or prize notice
☐ Move the money to a separate account if you want to track it
☐ Check the RWT rate on any account that will earn interest
☐ Decide on gifts before investing, so the interest is taxed to the right person
☐ Tell Work and Income about the win if you receive a benefit, because a lump sum can affect it
☐ Book an accountant for wins large enough to invest
Checklist: records worth keeping
Records help if Inland Revenue ever asks where a large deposit came from. Keep a note of every deposit and withdrawal you make at lucky elf, together with these documents:
☐ Bank statements showing deposits to and withdrawals from gambling accounts
☐ Screenshots or emails confirming large wins
☐ Prize notices or payout confirmations
☐ Dates and amounts of any money given to family
☐ Interest statements for the accounts holding the winnings
FAQ
Can I claim gambling losses against my income?
No, not as a recreational player. Since winnings aren't income, losses aren't a deduction either. Only someone whose gambling is treated as a business can offset losses, and in that case the winnings are taxed too.
Does a syndicate win change anything?
No, the prize stays tax-free for each member. We recommend a written agreement on how the prize is split: it shows that each share belongs to that member, and that each member pays tax only on the interest from their own share.
Are prizes from competitions or promotions taxed the same way?
Usually yes, if the prize comes from chance and not from work or a business arrangement. A prize received as part of employment or a sponsorship deal is treated differently and can be income.
Are winnings from an overseas lottery taxed in NZ?
Generally not in New Zealand, for the same reason as local prizes. The country that runs the lottery may still withhold its own tax before paying out, so the amount you receive can be smaller than the advertised prize. For a large overseas win, we suggest asking an accountant before you claim.
