Cashing out to a New Zealand bank account

What it costs, layer by layer

Four possible charges, and only two of them are usually significant.

The network fee to send crypto from your wallet to the platform's deposit address. Set by the blockchain, not the platform, and unavoidable. Cents on Solana, more on Bitcoin during congestion. Most wallets let you choose a slower, cheaper rate, and unless you are selling into a fast-moving market, slower is fine.

The trading fee or spread when you sell. This varies by platform and is usually the largest single cost. A market order on a liquid pair at a mainstream exchange is typically a fraction of a percent; a broker-style "instant sell" can be considerably more, because the margin is inside the quoted price rather than shown as a fee.

The NZD withdrawal fee. Often nothing. Swyftx charges no fee for New Zealand dollar withdrawals, and bank transfer withdrawals are free at most platforms. Check before you assume.

In-wallet sell routes. Some wallets offer to sell directly through a third-party provider, which is convenient and generally the most expensive option — the provider fee plus spread typically exceeds what an exchange charges. For anything sizeable, the extra ten minutes of using an exchange is worth real money. See our fees guide.

How long it actually takes

Plan for a day, and it is often faster.

The crypto transfer from your wallet to the platform confirms in minutes to an hour depending on the network and the fee you paid. Selling is instant once the deposit is credited, though platforms may hold a new deposit briefly before making it tradeable. The NZD withdrawal is typically same day to two business days, subject to the platform's payment run and your bank's processing.

Two things add delay. A first withdrawal to a newly added bank account often takes longer, because platforms apply additional verification when a payout destination changes — this is a sensible anti-fraud measure and worth pre-registering the account before you need it. And a large withdrawal from an account with limited history may trigger a manual compliance review. That is a normal AML process, not an accusation, and having clear records of where the crypto came from shortens the conversation considerably.

If you are selling to meet a specific payment deadline, start three business days early. Blockchains do not care about your settlement date and neither do compliance queues.

Bank questions and New Zealand banking history

Worth some context, because this is a genuine New Zealand quirk.

New Zealand banks have historically been cautious about crypto-related activity, and it has had real consequences for the industry rather than for individuals. BitNZ folded in 2017 because banks refused service. NZBCX ceased operating in 2021 for the same reason. Kiwi-Coin's closure in 2026 came amid banking difficulties. This is a structural feature of the market here, not an occasional inconvenience.

For an individual receiving an NZD withdrawal from a registered platform into an account in their own name, it is usually straightforward. Where questions arise, they tend to be about large or unusual amounts, and the bank is discharging its own AML obligations rather than disapproving of your choices. Answer honestly, and have the paper trail: when you bought, from whom, what you paid, what you sold, and to whom.

Two practical suggestions. Use the same bank account consistently rather than rotating between accounts, because a stable pattern generates fewer questions than a changing one. And if you are expecting a genuinely large withdrawal, a brief call to your bank beforehand is more pleasant than a frozen payment afterwards.

The tax side — this is a disposal

This is the step where tax actually arises, so it deserves care.

Inland Revenue treats cryptoassets as a form of property, and its published position is that the tax treatment depends on the characteristics and use of the asset. New Zealand has no general capital gains tax — but income from selling, trading or exchanging cryptoassets is taxable where your purpose in acquiring them was disposal, where you are engaged in trading, or where they formed part of a profit-making scheme.

In practice that is a wide net. Most people who buy Bitcoin do so expecting to sell it for more later, which is an acquisition for the purpose of disposal. The comfortable assumption that a long holding period makes a gain capital and therefore untaxed is not a position to adopt without advice.

What you need at the point of sale: the NZD proceeds, the NZD cost base of what you sold, the fees at both ends, and the dates. Where you have taxable cryptoasset income you file an IR3 and must be able to calculate the New Zealand dollar value of your transactions. Note also that a crypto-to-crypto swap earlier in the chain was itself a disposal, which is where people who traded actively find their records are thinner than they hoped.

And the reason this matters more than it did: from 1 April 2026 reporting crypto-asset service providers collect identity and transaction data and report it to Inland Revenue under CARF, with the first reports due by 30 June 2027 and information shared internationally. The platform you sell through reports the sale. Your records are what establish the cost base against it.

This is general information and not tax advice — for anything material, use an accountant with cryptoasset experience.
