Best Card to Use Overseas From New Zealand (2026)

Your New Zealand bank charges you twice every time you tap a card overseas: a foreign transaction fee of between 0% and 2.5% depending on which bank and which card, and a margin inside the exchange rate that nobody itemises. On a NZ$4,000 two-week trip the combined cost is typically NZ$160–200. This page lists what each of the big five actually charges as at 8 August 2026, shows the arithmetic on a real trip, and sets out which cards belong in your wallet — because the right answer is two or three cards, not one.

What the big five actually charge

These figures come from each bank's own published fee schedules and help pages as at 8 August 2026. Fees change — check yours before you fly, and note that where a bank publishes a percentage, the exchange rate margin sits on top and is not included.

Bank	Debit card FX fee	Credit card FX fee	Overseas ATM fee (bank's own)
ANZ	1.3% of the NZD amount, including overseas ATM withdrawals	Nil on personal credit cards. 1.3% on business cards.	No ANZ fee; the ATM operator may charge
ASB	2.10% Offshore Service Margin on Visa Debit (1.10% on FastCash / CashFlow cards)	2.10% Offshore Service Margin	Not separately published; margin applies to the converted amount
BNZ	2.25% foreign currency service fee	2.25% foreign currency service fee	No BNZ charge on overseas ATM withdrawals; the 2.25% still applies
Westpac	1.83% foreign currency fee	1.83% personal; 2.50% business. Fee Free Mastercard: nil.	Not separately published on the help page
Kiwibank	2.5% of the converted NZD amount	1.85% of the converted NZD amount	NZ$6 per overseas ATM withdrawal

Three observations worth more than the table itself.

The debit/credit split is real and it's backwards from what people assume. At Kiwibank the debit card costs 2.5% and the credit card 1.85%. At ANZ the debit card costs 1.3% and the personal credit card costs nothing. Most travellers reach for debit overseas because it feels safer. On fees it's usually the worse choice.

The fee applies to online purchases too. ANZ's own wording covers foreign transactions "both online and overseas". If you buy from a US or UK website from your couch in Ōtaki, you're paying it. It is not a travel fee; it's a foreign-currency fee.

The percentage is not the whole cost. On top of the bank's fee, the transaction converts at the Visa or Mastercard scheme rate. Scheme rates are reasonably close to mid-market — much closer than a bureau's rate — but they are not the mid-market rate, and where a bank sets the rate itself the gap can be materially wider. That invisible slice is why a "2%" card can cost 3–5% in practice.

What it actually costs: a NZ$4,000 two-week trip

Assume NZ$3,400 on the card and NZ$600 out of ATMs, in one currency, with no dynamic currency conversion mistakes.

Card used	Stated fee	Fee on NZ$4,000	Rate margin at 2.5%	ATM fees	Total cost
Kiwibank debit	2.5%	NZ$100	NZ$100	NZ$6 × 4 = NZ$24	~NZ$224
BNZ debit or credit	2.25%	NZ$90	NZ$100	Operator fees only	~NZ$190+
ASB Visa Debit	2.10%	NZ$84	NZ$100	Operator fees only	~NZ$184+
Westpac personal	1.83%	NZ$73	NZ$100	Operator fees only	~NZ$173+
ANZ debit	1.3%	NZ$52	NZ$100	Operator fees only	~NZ$152+
ANZ personal credit	Nil	NZ$0	Scheme rate — small	Don't use for cash	~NZ$20–50 on spending
Wise	From 0.25%	~NZ$10–24	Nil — mid-market rate	NZ$400 free/month, then 2.69%	~NZ$30–45 incl. NZ$14 card

The headline number people fixate on — 2% versus 1.3% — is the smaller half of the problem. The rate margin is the larger half, and it's the one that disappears entirely when you convert at the mid-market rate. That's NZ$150–190 back in your pocket on a single trip, which is a decent night out in Tokyo or three days of scooter hire in Bali.

Debit vs credit vs prepaid vs multi-currency

Debit card

Good for: ATM cash, staying inside your budget, no interest risk.
Bad for: fees (usually the highest FX percentage at your bank), and deposits. A fraudulent charge or a mistaken hotel hold takes real money out of your transaction account and you wait for it to come back. Never travel with your main account attached to the card in your pocket — open a separate everyday account and sweep money into it.

Credit card

Good for: chargeback protection, rental car and hotel holds, sometimes free travel insurance, and — at ANZ and on Westpac's Fee Free Mastercard — no FX fee at all.
Bad for: cash. A credit card ATM withdrawal is a cash advance: interest normally accrues from the day of the transaction with no interest-free period, plus a cash advance fee. Withdrawing NZ$300 on a credit card can cost more than the notes are worth in convenience terms. Use credit to spend, never to withdraw.

Prepaid travel card

Good for: handing to a teenager, hard budget caps, and buying today at a store counter.
Bad for: almost everything else. The FX margin is inside the load rate at 3–5%, cross-currency charges run 4–5.95%, inactivity fees apply, closure fees apply, and holds and deposits are a problem. Full breakdown on our travel money card NZ comparison.

Multi-currency account and card

Good for: the actual mid-market rate, holding several currencies at once, converting when you choose rather than when a counter tells you, cheap ATM access, and receiving money in foreign currency if you work or get paid overseas.
Bad for: deposits and holds, and it won't give you notes in New Zealand. Wise holds 40+ currencies with local account details in 9+ of them; our Wise review for New Zealand covers the regulatory position, which is that Wise Payments Ltd operates here as a foreign entity and is not licensed by a New Zealand regulator, though it is supervised by the Department of Internal Affairs for AML purposes.

Travel insurance and paying by credit card

A lot of New Zealanders believe their credit card includes travel insurance. Some do — usually gold, platinum and airline-branded cards. The conditions are where people come unstuck, and they are strict:

• You normally must pay for a minimum portion of the trip on that card — often a set dollar amount of prepaid travel costs, or the full international airfare. Book the flights on a debit card and the cover may simply not exist.
• You often have to activate it before departure and declare pre-existing conditions.
• Trip length is capped, commonly 30–90 days per journey.
• It rarely covers everything — rental car excess, adventure activities, motorbikes and electronics limits are the usual gaps.

Practical implication: if you're relying on card-included insurance, the flights and accommodation should go on that credit card even if a cheaper card exists on fees. Then ring the insurer and get the policy wording emailed to you. And whatever the card promises, check whether it covers medical evacuation — that's the cost that bankrupts people, not a lost suitcase.

Card holds on rental cars and hotels

This is the single most important reason not to travel with only a prepaid or debit card, and it's the thing card comparison pages don't mention.

When you pick up a rental car, the company places an authorisation hold — commonly the equivalent of NZ$300 to NZ$1,500, higher for premium vehicles or if you decline their excess cover. Hotels do the same for incidentals, often NZ$100–300 per night in the USA. A hold on a credit card ties up part of your credit limit, which you don't feel. A hold on a debit or prepaid card takes actual money out of your available balance and can sit there for 5–15 business days after you check out.

Beyond the cash-flow problem, a lot of rental companies flatly refuse to accept a prepaid or debit card for the deposit, and some require a credit card in the driver's name matching the licence. Turning up in Los Angeles or Brisbane with a prepaid travel card and a booking reference is a well-documented way to spend an hour at a counter. Some will accept debit with a second form of ID and a bigger hold; some will not accept it at all.

What to actually carry in your wallet

1. A no-FX-fee credit card for card-present spending, deposits and holds. ANZ personal credit cards and the Westpac Fee Free Mastercard both charge no foreign currency fee. Check whether it also carries travel insurance and what you must pay on it to trigger cover.
2. A Wise card for ATM withdrawals and for holding the currencies of the countries you're visiting. NZ$400 free withdrawals a month, then 2.69%; conversion from 0.25% at the mid-market rate.
3. Your everyday bank debit card as a backup, on a different network from the credit card. Know its fee: 1.3% to 2.5% depending on the bank.
4. NZ$150–300 equivalent in local cash, bought in New Zealand before you fly, split between your wallet and your bag. This is for taxis, tips, market stalls, temple entry and the one shop that still refuses cards. See how much cash you need by country.
5. A photo of the front and back of every card, stored somewhere you can reach without the cards. Plus the international collect-call number for each issuer.

Get the cash from a bureau in New Zealand rather than at the destination airport. Our guides to currency exchange near you and Queenstown Airport currency exchange cover where the rates are least punishing, and sending money overseas from NZ covers the case where you need funds to land in someone else's account rather than your own pocket.

Five ways people lose money that have nothing to do with fees

• Accepting dynamic currency conversion. The terminal asks whether you want to be charged in NZD. Say no, every time. It costs 3–6%, which is bigger than any bank fee on this page. Full explanation on our page on whether to pay in NZD or local currency.
• Withdrawing NZ$60 at a time. Fixed ATM fees — NZ$6 at Kiwibank, US$3–5 from many American operators — are brutal on small withdrawals. Take out larger amounts, less often.
• Using standalone ATMs in tourist strips. Euronet-style machines in airports and beach fronts charge high fees and push DCC hard. Use ATMs attached to bank branches.
• Not telling the bank you're travelling. Most banks no longer require it, but a first transaction in an unusual country still triggers blocks. Check your bank's app for a travel notification.
• Cash advance on a credit card. Interest from day one, plus a fee. If you need cash, use a debit or multi-currency card.

Frequently asked questions

What is the best card to use overseas from New Zealand?

A combination: a no-FX-fee credit card for spending and deposits (ANZ personal credit cards and the Westpac Fee Free Mastercard charge no foreign currency fee), a Wise card for ATM cash and holding currency at the mid-market rate, and your bank debit card as backup. No single card does all three jobs well.

Which NZ bank has the lowest foreign transaction fee?

As at August 2026, ANZ charges nothing on personal credit cards and 1.3% on debit cards — the lowest of the big five. Westpac is 1.83% on personal cards with a nil-fee Fee Free Mastercard, ASB 2.10%, BNZ 2.25%, and Kiwibank 2.5% on debit and 1.85% on credit. Confirm against your bank's current schedule before travelling.

Should I use debit or credit overseas?

Credit for spending, deposits and holds — better fraud protection, no money leaves your account, and often a lower FX fee. Debit or a multi-currency card for ATM cash, because a credit card withdrawal is a cash advance that accrues interest from day one plus a fee.

Do NZ banks charge foreign transaction fees on overseas online shopping?

Yes. The fee applies to any transaction in a foreign currency, whether you're standing in a shop in Bangkok or buying from a US site at home. ANZ's own wording covers foreign transactions "both online and overseas". Some banks also apply it where a New Zealand-looking merchant settles offshore.

How much does a 2% foreign transaction fee cost on a NZ$4,000 trip?

The fee itself is NZ$80. Add a typical 2–3% exchange rate margin — NZ$80 to NZ$120 — and the real cost is NZ$160–200. Converting the same NZ$4,000 at the mid-market rate with a 0.25–0.6% visible fee costs roughly NZ$10–24.

Can I use a prepaid travel card for a rental car deposit?

Often not. Many rental companies refuse prepaid and debit cards for the security hold, and those that accept debit usually demand extra ID and a larger hold. Bring a credit card in the driver's name that matches the licence.

Does my NZ credit card include travel insurance?

Some gold, platinum and airline cards do, but the conditions are strict: you normally must pay a minimum portion of the trip — often the full international airfare — on that card, activate the cover before departure, declare pre-existing conditions, and stay within a trip-length cap of about 30–90 days. Read the policy wording before you rely on it.

Is it cheaper to take cash or use a card overseas?

Cards are cheaper for the bulk of your spending if you use one that converts at or near the mid-market rate. Cash bought from a New Zealand bureau typically costs 3–7% in the rate. That's why the split works: NZ$150–300 in cash for the situations cards can't cover, and 90% on a card at the real rate.
