New Zealand’s tax treatment of cryptocurrency and gambling winnings is governed by the Income Tax Act 2007 and Inland Revenue (IRD) guidance. The two areas intersect at crypto casinos: when you deposit cryptocurrency, play casino games and withdraw winnings, multiple potential tax events can arise depending on how IRD classifies your activity. This guide explains the current rules as published by IRD, where the grey areas are, and what records to keep if you use crypto at NZ casinos.
Important: This guide is educational information only and is not tax advice. Tax rules can change. For advice specific to your circumstances, consult a New Zealand tax professional or contact IRD directly.
How IRD classifies cryptocurrency
IRD treats cryptocurrency as property, not currency. This classification has important consequences for tax:
- Disposing of cryptocurrency is a taxable event if the cryptocurrency was acquired with a profit-making intention, or if it forms part of a business
- Exchanges between cryptocurrencies (e.g. converting Bitcoin to Ethereum) are treated as a disposal and acquisition — potentially taxable
- Using crypto to purchase goods or services (including depositing at a casino) is treated as a disposal at the current market value
IRD has published guidance on cryptocurrency in IS 21/01 (Income Tax — Cryptocurrency). The key principle is that cryptocurrency is not treated as money for tax purposes.
Are gambling winnings taxable in New Zealand?
New Zealand does not have a general capital gains tax. More relevantly for most casino players, gambling winnings from casual recreational gambling are not taxable income under New Zealand tax law.
The principle is established in case law and IRD guidance: winnings from recreational gambling are not income because gambling is not a systematic activity undertaken for profit with a reasonable expectation of success. A person who plays casino games recreationally and wins is not taxed on those winnings.
However, there are exceptions. Winnings can become taxable if:
- The gambling is conducted as a business or profession (e.g. professional poker players who treat gambling as their primary income source)
- The winnings are received as employment income (e.g. a casino employee winning as part of a work promotion)
- The activity involves prize winnings from a competition entered for commercial purposes (distinct from casino gambling)
For the vast majority of NZ players who gamble recreationally at online casinos, winnings are not taxable income.
Where cryptocurrency creates tax complications
Even when the gambling winnings themselves are not taxable, the cryptocurrency used to deposit and withdraw can create separate tax events:
Depositing crypto at a casino
When you deposit Bitcoin (or any crypto) at a casino, IRD treats this as a disposal of property at the current market value. If you bought Bitcoin at NZ$50,000 per coin and its value has increased to NZ$70,000 when you deposit, the NZ$20,000 increase may be taxable — but only if you originally acquired the Bitcoin with a profit-making purpose.
This is the grey area in NZ crypto tax: IRD’s guidance distinguishes between:
- Investment/speculative purpose: Buying crypto with the intention of selling it at a profit — taxable on disposal
- Currency/exchange use: Buying crypto to use as a medium of exchange (e.g. to deposit at a casino) — not subject to the same profit-making intention test
In practice, establishing the original purpose at time of acquisition is the critical question. IRD has not issued specific guidance on crypto purchased solely to gamble with.
Receiving crypto winnings from a casino
If you withdraw cryptocurrency winnings, those winnings are received in crypto at the market value at withdrawal time. As gambling winnings (assuming recreational), the withdrawal itself is not taxable. But the crypto you now hold has a cost basis of zero (if the winnings are not taxable income) or the market value at withdrawal (if they are). The treatment of any subsequent gain when you sell or exchange that crypto depends on how you acquired it.
Converting crypto winnings to NZD
Selling cryptocurrency (including converting casino winnings to NZD) is a disposal. The taxable gain is the difference between your cost basis and the sale price. If the gambling winnings were not taxable, your cost basis in the crypto received is its market value at the time of withdrawal. If you withdraw NZ$1,000 equivalent in Bitcoin and sell it the same day for NZ$1,000, the gain is zero regardless. If it appreciates before you sell, that appreciation may be taxable under the profit-making purpose test.
Record-keeping for crypto casino activity
Given the complexity, keeping records is essential regardless of whether you believe any activity is taxable:
Records to keep:
- Date and amount of every crypto deposit (in NZD value at time of deposit)
- Date and amount of every crypto withdrawal (in NZD value at time of withdrawal)
- Transaction IDs for all on-chain transfers
- The exchange rate source used (e.g. CoinGecko, Coinbase, the exchange you used)
- Your original purchase records for any crypto used at the casino
Crypto exchanges and wallets maintain their own records, but they may not be accessible indefinitely and their records do not substitute for your own notes on purpose and value at each transaction point.
Several crypto tax software tools (Koinly, CoinTracking, TaxBit) integrate with exchanges and wallets to generate NZ-compliant transaction reports. These tools calculate gains and losses automatically based on import data from exchanges.
When to seek professional advice
Consult a New Zealand tax adviser if:
- You use cryptocurrency regularly at casinos and the amounts are significant
- Your crypto holdings have increased substantially in value since purchase
- You have received crypto from multiple sources (wages, staking rewards, casino winnings, trading) and are unsure of the cost basis
- You are unsure whether your gambling activity qualifies as recreational or approaches a business in frequency and organisation
IRD also operates a free telephone advice service and has published detailed guidance on cryptocurrency at its website (ird.govt.nz).
Practical summary for NZ crypto casino players
| Situation | NZ tax treatment |
|---|---|
| Recreational casino winnings (NZD) | Not taxable |
| Recreational casino winnings (crypto) | Not taxable as gambling winnings |
| Gain on crypto before depositing at casino | May be taxable (profit-making purpose test) |
| Gain on casino crypto after withdrawal | May be taxable if sold at a gain |
| Converting casino crypto winnings to NZD | Disposal; gain calculated from cost basis |
For the vast majority of NZ players who gamble recreationally and use crypto as a deposit method without large capital gains, the practical tax burden is low or zero. The complication arises when crypto is held and appreciates significantly, or when activity frequency approaches a business.

Frequently asked questions
Does IRD know about my crypto casino activity? New Zealand exchanges (those operating under the Anti-Money Laundering and Countering Financing of Terrorism Act) are required to collect identity information and may share it with IRD. Offshore casinos and international exchanges are not subject to NZ reporting requirements but may be subject to information exchange under international tax agreements. IRD has been increasing crypto enforcement activity since 2021.
Are poker winnings taxable in New Zealand? Under the same recreational gambling principle, casual poker winnings are not taxable. Professional poker players who treat poker as their primary income source occupy a different position — IRD has assessed professional gamblers as carrying on a business in some cases, making their winnings taxable. The frequency, organisation and profit expectation of the activity are the key factors.
What is the difference between capital gains and income in NZ crypto tax? New Zealand does not have a separate capital gains tax. Gains from property disposals (including crypto) are taxed as ordinary income if the asset was acquired with a profit-making purpose. The tax rate is your personal income tax rate (10.5%, 17.5%, 30%, 33%, or 39% on income over NZ$180,000).
Should I report crypto casino activity on my tax return? If recreational gambling winnings are not taxable, you are not required to report them. If you have made taxable gains on crypto (through appreciation and disposal), those gains should be reported regardless of whether they relate to casino activity. When in doubt, consult an accountant.
