Kiwi readers looking at crypto casinos should understand a changing legal picture first. We compare Duel and Bitz and explain the situation plainly.
Is online casino play legal in New Zealand?
Gambling in New Zealand is regulated under the Gambling Act 2003, administered by the Department of Internal Affairs (DIA). Overseas gambling sites are not licensed by New Zealand. Law-firm and industry reports say the Online Casino Gambling Act 2026 passed in April 2026 and sets up up to 15 licences, with licence applications running to 1 December 2026 and only licensed operators allowed from 1 June 2027. We could not confirm these dates on the DIA site, so check the DIA for the current timetable and register of licensed operators.
Not locally licensed. Duel and Bitz both hold an international Anjouan licence, not a licence issued in New Zealand. Until you can verify an operator on the official DIA register, treat it as unlicensed in New Zealand, with no local complaints route.
What this means for you
Neither Duel nor Bitz has been confirmed as licensed in New Zealand. Check each operator's terms and restricted-countries list to see whether Kiwi players are accepted, and watch for the DIA licence register once it is published. If a site restricts your location, respect that. Terms may change quickly, so re-check before you deposit; see our ranking for criteria.
A changing law is a reason for extra care rather than a reason to rush. Reports of reform mean the situation described on any comparison site, including this one, can go out of date. Treat this page as a starting point and confirm the current position with the DIA before you act. We do not give legal advice, and we do not suggest ways around any restriction an operator or the law places on New Zealand players.
A simple way to keep up with changes
| What to check | Where | Why it matters |
|---|---|---|
| Current legal position for online casinos | The DIA gambling legislation pages | Reported reforms may change what is allowed and when |
| Register of licensed operators | The DIA, once published | An operator on the register is licensed locally; one that is not should be treated as unlicensed in New Zealand |
| Operator terms and restricted countries | Duel and Bitz terms pages | Terms can change quickly and may affect whether Kiwi players are accepted |
| Bonus conditions | The Bitz promotion terms | Wagering, free-spin game and max bet are not published in our information |
For a plain-language look at what an Anjouan licence does and does not mean, see our crypto casino safety guide.
How we compare Duel and Bitz for Kiwi readers
Our method is to compare what each operator publishes: licence, supported coins, bonus structure and withdrawal policy. We do not state that we deposited, played or timed payouts, and we do not include user reviews. The ranking criteria are explained in the full Bitcoin casino ranking, and the individual write-ups are the Duel review and the Bitz review.
For New Zealand readers the questions that matter most tend to be these.
- Legal status. No New Zealand licence has been confirmed for either operator.
- Funding in NZD. Balances are normally shown in USD or USDT, so a conversion step is needed.
- Coin options. Bitcoin, stablecoins and other networks each have different trade-offs.
- Bonus design. Rakeback and a welcome match solve different problems.
- Exit process. Verification and manual review can slow a withdrawal even when speed is advertised as fast.
Duel vs Bitz
Both operators are ranked on published terms only. Details below come from the operators' public information; our full ranking explains the criteria.
| Feature | Duel | Bitz |
|---|---|---|
| Rating | 9.6/10 | 9.4/10 |
| Licence | Anjouan (international) | Anjouan (international) |
| Bonus model | No traditional welcome bonus; instant rakeback on every bet | 200 % crypto match + 250 free spins, up to 1,500 USDT |
| Withdrawals | Advertised as instant; some go to manual review; KYC may be requested | Processed in up to 10 minutes |
| Crypto | BTC, ETH, USDT, USDC, SOL, TON | USDT, USDC, BTC, ETH, SOL, TON, Lightning |
| Promo code | KINGZWIN | KINGZWIN |
As a hypothetical example only: a 750 USDT deposit would reach the 1,500 USDT cap on the Bitz match. Check the promo terms before depositing. Read both operators' pages: Duel and Bitz (code KINGZWIN). More on bonuses is in our bonus guide.
Duel in brief
Duel skips the traditional welcome bonus and pays instant rakeback on every bet. Its Originals are advertised with a 0 % house edge within a daily limit, and payouts are advertised as instant, although some withdrawals go to manual review and KYC may be requested. Supported coins are BTC, ETH, USDT, USDC, SOL and TON. Deposit-limit tools could not be confirmed from public information, so consider setting your own limit at the wallet or bank level.
Bitz in brief
Bitz offers a 200 % crypto match plus 250 free spins, up to 1,500 USDT, with withdrawals processed in up to 10 minutes. It supports USDT, USDC, BTC, ETH, SOL, TON and Lightning, with slots from big providers and live casino. Wagering, the free-spin game and the max bet are not published in our information, so the promotion terms must be read before you accept.
Strengths for Kiwi readers
- Stablecoin options that reduce price swings
- Two distinct bonus approaches
- Fast withdrawals advertised by both operators
- Lightning at Bitz for Bitcoin users
Cautions for Kiwi readers
- No New Zealand licence confirmed for either operator
- Legal framework reportedly changing
- Acceptance of New Zealand players not confirmed
- Manual review and KYC possible at Duel; Bitz bonus terms unpublished
Currency and crypto tips for New Zealand players
Operators typically display USD or USDT, so converting NZD involves an exchange rate and fees that vary. Stablecoins (USDT, USDC) reduce price swings, whereas BTC and ETH can move sharply between deposit and cash-out. Network fees vary with network load; Lightning, supported by Bitz, is a faster-settling option for Bitcoin. See the payments guide. Check tax treatment with an adviser.
Think of the money path as a chain: NZD to an exchange, exchange to a wallet, wallet to the operator, and then back again. Every link can carry a fee or a rate spread, and any link can fail if you pick the wrong network. Keeping the chain short and the amounts small while you learn is the cheapest insurance.
| Coin or network | Listed at | What to weigh |
|---|---|---|
| BTC | Duel, Bitz | Widely held and easy to buy, but the price can move between deposit and cash-out; fees and speed vary with network load |
| Lightning (Bitcoin) | Bitz | A second layer built for smaller, faster Bitcoin payments; both your wallet and the casino must support it |
| ETH | Duel, Bitz | Price can swing; network fees vary with demand |
| USDT | Duel, Bitz | Dollar-pegged stablecoin; check which network you send on, because the same coin exists on several |
| USDC | Duel, Bitz | Another dollar-pegged stablecoin; the same network-matching rule applies |
| SOL | Duel, Bitz | Separate network with its own wallets and addresses; never send it to an address meant for another chain |
| TON | Duel, Bitz | Separate network again; some deposits may need extra details, so read the deposit screen carefully |
Bitcoin on-chain, Lightning or a stablecoin?
On-chain Bitcoin is the most familiar route and works with almost every wallet, but the fee and the wait both vary with network load. Lightning is built for quicker, smaller payments and is available at Bitz, though it needs a Lightning-capable wallet and enough channel liquidity to send or receive. Stablecoins keep the value of your balance steady in US dollar terms, which makes bankroll tracking easier, but you must send them on the network the operator specifies. If you are new, a stablecoin on a single, clearly labelled network is usually the least confusing place to start.
Step-by-step: preparing a deposit
- Confirm eligibility. Read the operator's terms and restricted-countries list for New Zealand.
- Check the current legal position. Visit the DIA pages linked above, as the rules are reported to be changing.
- Set a budget and a time limit. Write them down before you buy any crypto.
- Buy your coin. Use an exchange that lets you compare NZD fees, and note the rate you receive.
- Match coin and network. Check the deposit screen to see exactly which network the address belongs to.
- Send a small test. Wait for it to arrive before sending the rest.
- Read the bonus terms. If anything is unclear, decline the bonus.
- Prepare for withdrawal. Keep your ID and proof of address handy, as KYC may be requested.
Tip: save the confirmation details for each transfer, including the date, amount and transaction ID. If something goes wrong, those details are what support teams ask for first.
More on wallets and networks is in the payments guide. If cash-out speed is your main concern, see our page on fast-withdrawal Bitcoin casinos.
Worked examples (hypothetical)
These examples use invented figures to illustrate mechanics. They are not the terms of Duel, Bitz or any real promotion.
Example 1: reaching the Bitz cap
With a 200 % match, the bonus equals twice the deposit. A 750 USDT deposit would therefore reach the 1,500 USDT cap. Depositing 1,000 USDT would not raise the match above the cap. A 200 USDT deposit would, in principle, give a 400 USDT match. How the bonus and deposit are treated under wagering depends on the full terms, so read them first.
Example 2: the cost of a wagering multiple
Picture a made-up bonus of 200 USDT with a wagering requirement of 40 times the bonus. You would need to place 8,000 USDT of bets before withdrawing winnings from it. The figure here is illustrative only; the lesson is to multiply any requirement out and ask whether you would realistically stake that much anyway. See the bonus guide for a checklist.
Example 3: a price swing between deposit and cash-out
Imagine you deposit an amount of Bitcoin, play a short session, and withdraw the same amount of Bitcoin. Even if you break even in Bitcoin terms, the NZD value may have risen or fallen in between. With a stablecoin the swing is largely removed, though the exchange fees at either end remain. This is why many players track their results in the unit they deposit rather than in NZD.
If you are in this situation, then consider this
| If you... | Then consider... |
|---|---|
| Want ongoing value without bonus conditions | Understanding how rakeback works at Duel |
| Want a large starting boost | Reading the Bitz offer and its terms line by line |
| Use Lightning-capable wallets | Checking how Bitz handles Lightning deposits and withdrawals |
| Want fewer price surprises | Using a stablecoin on one verified network |
| Are unsure about legality right now | Pausing until you have checked the DIA position and the operator's terms |
| Notice you are playing to win money back | Stopping and contacting the Gambling Helpline |
Common mistakes to avoid
- Treating reform news as settled fact. Reported dates and numbers should be checked with the DIA.
- Assuming an international licence equals a local one. Anjouan is not a New Zealand licence.
- Skipping the restricted-countries list. Acceptance is set by the operator and can change.
- Using the wrong network. Sending a coin on a chain the address does not support can lose funds.
- Accepting a bonus first and reading later. The terms decide whether the offer is worth taking.
- Leaving winnings parked. Withdraw what you do not need and keep your own custody.
- Gambling with money meant for essentials. Only use disposable entertainment money.
Verification and withdrawals
Duel advertises payouts as instant, with some withdrawals going to manual review and KYC possible before withdrawal. Bitz states withdrawals are processed in up to 10 minutes. These are operator statements; the real experience depends on your account status, the coin and network you choose, and how busy that network is. Having your documents ready and your name matching on every account is the simplest way to avoid delays.
Never send identity documents by email or messaging apps that the operator has not clearly set up for that purpose. Use the verification area of your account. Our responsible gambling page also covers how to set personal limits when an operator does not offer deposit-limit tools.
Tax and records
Whether gambling winnings or crypto transactions have tax consequences depends on your circumstances, so ask a qualified New Zealand adviser. For your own purposes, keep a record of each deposit and withdrawal with dates, coins, amounts and exchange rates, which makes any later conversation with an adviser much easier.

More questions from Kiwi readers
Will a licensed local market change the picture?
If the reported reforms take effect, the DIA register is likely to become the key reference for which operators are licensed in New Zealand. Until then, check the DIA directly. Other general questions are answered in our FAQ.
Is rakeback better than a welcome bonus?
It depends on how you play. Rakeback returns value as you bet, with no large upfront conditions, while a match bonus gives a bigger starting balance but usually comes with wagering. Compare the conditions rather than the headline.
Responsible gambling in New Zealand
You must be of legal age (18+). Set limits before you play, never chase losses and only stake money you can afford to lose. Crypto balances can swing in value, which adds a second kind of risk. See our responsible gambling page.
Warning signs include playing for longer than planned, borrowing to gamble, hiding activity from people close to you and feeling restless when you stop. If any apply, reach out early; support is free and confidential.
The Gambling Helpline Aotearoa offers free support on 0800 654 655 (7 days a week) or text 8006. Specialist lines include Māori (0800 654 656), Pasifika (0800 654 657), Youth (0800 654 659) and Gambling Debt (0800 654 658).
International support is available from Gambling Therapy.
Verdict
Duel suits players who prefer rakeback; Bitz suits those who want a large welcome match and Lightning. Legality for Kiwi players needs checking and may be changing. Before signing up, confirm in each operator's terms and restricted-countries list that New Zealand is accepted, and read our safety guide. If the picture is not clear, wait until it is.
