Should I Pay in NZD or Local Currency? Always Local — Here's Why

You are at a till in Rome. The card machine turns towards you and offers two buttons: pay €84.00, or pay NZ$158.20. The NZD figure feels safer — you know what it means. Press it and you have just paid somewhere between 3% and 6% more than you needed to. Always choose the local currency. That is the whole answer, and it holds for every card, every country and every machine. The rest of this page explains why, so you'll recognise the trap in its other disguises — receipts, ATMs, hotel checkouts and online checkouts.

What dynamic currency conversion actually is

DCC is a service sold to merchants and ATM operators, not to you. When you insert a New Zealand-issued card, the terminal reads the card's home currency from the card number and offers to do the conversion at the point of sale instead of leaving it to Visa or Mastercard.

The pitch to the merchant is a share of the markup. The pitch to you is certainty: "know exactly what you'll pay in your own currency." That certainty is real. It's also worth nothing, because the amount you're being shown is worse than the amount you'd otherwise be charged, and you'll know your NZD total within a day or two anyway when the transaction settles.

Here's the part that surprises people. Accepting DCC does not get you out of your own bank's foreign transaction fee. Most New Zealand issuers treat a transaction as foreign based on where the merchant is, not what currency was billed. So an ASB Visa Debit user who accepts DCC in Rome pays the DCC markup and ASB's 2.10% Offshore Service Margin. You've been charged twice for one conversion.

The worked example

A €84.00 dinner in Rome. Say the mid-market rate that day is 1 EUR = 1.83 NZD, so the true value is NZ$153.72.

What you press	Conversion	Your bank's fee	Total	Extra cost
Local currency (€84.00) on a Wise card	Mid-market rate: NZ$153.72	Conversion fee from 0.25% ≈ NZ$0.38–0.92	~NZ$154.10–154.64	Baseline
Local currency (€84.00) on a BNZ card	Scheme rate, roughly NZ$154.50	2.25% = NZ$3.48	~NZ$157.98	+NZ$3.90
NZD (DCC) at a 4.5% markup on a BNZ card	DCC rate: NZ$160.64	2.25% still applies = NZ$3.61	~NZ$164.25	+NZ$10.53
NZD (DCC) at a 6% markup	DCC rate: NZ$162.94	2.25% = NZ$3.67	~NZ$166.61	+NZ$12.89

Work out what a specific amount costs you:

One button press, NZ$10 on a single dinner. Do it at every restaurant, hotel and shop for two weeks and you've paid for a decent day trip. Across a NZ$4,000 trip where you accept DCC on everything, a 4–6% markup is NZ$160–240.

Note the top row. The cheapest outcome isn't just "decline DCC" — it's decline DCC and hold the currency on a card that converts at the mid-market rate. Those are two separate savings that stack.

Exactly what the prompt looks like

DCC is deliberately designed so that the expensive option looks like the helpful one. The wording varies but the pattern doesn't:

• Two amounts, two buttons. The local currency amount and an NZD amount. The NZD button is often larger, greener, higher up, or labelled with something friendly.
• "Would you like to pay in NZD?" with YES highlighted. Press NO.
• "Select your currency: NZD / EUR." Select the local currency, not NZD.
• "Pay in your home currency — no surprises." Decline.
• An exchange rate displayed on screen, sometimes with wording like "conversion at a rate of 1 EUR = 1.912 NZD, including a X% margin". If a rate is on the screen at all, DCC is being offered. Payment terminals do not otherwise need to show you a rate.

Two practical notes. Sometimes the staff member presses it for you before handing the machine over — in tourist districts this is routine, because the venue earns a share. It's fine to say "local currency, please" as you hand over the card, or to hand it back and ask them to redo it. Second, on some terminals DCC cannot be reversed once selected; the transaction has to be voided and re-run. Speak up before it goes through, not after.

How to spot DCC on a receipt

Check your receipts on the first day or two of a trip. You'll learn which venues do it and can be ready. Look for:

• A total in NZD on a receipt from a shop that prices everything in the local currency.
• Both currencies printed, with an exchange rate between them.
• Wording like "Transaction currency: NZD", "Cardholder currency", "DCC", or "I have been offered a choice of currencies and elected to pay in NZD" — that last line is the one that appears above the signature strip, and it exists for the merchant's protection, not yours.
• A rate that looks a long way from the mid-market rate. Compare it to your phone.

The ATM version — and the airport version

ATMs run the same play, and it's worse there because it stacks with the machine's own fees.

You ask for €200. The screen says something like: "Withdraw with conversion: NZ$382.40, rate 1 EUR = 1.912 NZD", with options along the lines of "Accept conversion" and "Decline conversion — continue without conversion". Choosing "decline conversion" feels like it might cancel your withdrawal. It doesn't. It means the ATM hands over your €200 and lets your own card issuer do the conversion, which is what you want. Press decline every time.

The airport arrival ATM stack

The most expensive cash you will ever touch is the cash from a standalone ATM in an arrivals hall. Here is what happens in sequence:

1. An operator surcharge — commonly the equivalent of NZ$5–12 for a non-bank machine, and airport machines sit at the top of that range.
2. A DCC offer at a 4–7% markup, pre-selected or with the accept button placed where your thumb naturally lands.
3. Your own bank's fee on top — 1.3% to 2.5%, plus NZ$6 per withdrawal if you're with Kiwibank.
4. A low withdrawal cap, so you do it twice.

Withdraw €200 through all four layers and you can lose NZ$30–45 on NZ$380 of cash — around 10%. That's worse than the airport currency desk you were avoiding.

What to do instead: buy your first NZ$150–300 of local cash in New Zealand before you fly, so you land with taxi and coffee money and don't have to touch an arrivals ATM at all. Our guides to Auckland Airport currency exchange and currency exchange services across NZ cover where to get it, and the cheapest way to exchange money in New Zealand compares rates. Then, once you're in the city, use an ATM attached to a bank branch for anything more.

Online checkouts do it too

DCC isn't only physical. Book a hotel or a flight on an overseas site and you'll often be offered a NZD price alongside the local one, sometimes with the NZD price pre-selected because the site detected your location. Airlines and hotel booking platforms are frequent offenders, and hotel front desks will do it again at checkout on the same booking. Choose the local currency at both ends, and if the hotel has already billed you in NZD, ask them to void and re-run it in local currency before you leave the desk.

Can you get a refund if you were charged DCC?

Sometimes. It's worth trying, and it works most often when you catch it fast.

1. At the counter, immediately. This is where you'll actually succeed. Ask them to void the transaction and re-run it in local currency. Most terminals can do this within the same trading day.
2. At the hotel before checkout. Same request, same day. Front desks do this regularly.
3. Afterwards, with the merchant. Email with the receipt attached and ask for the DCC markup to be refunded, citing that you weren't given a genuine choice of currency. Some will refund the difference to keep the peace; many won't.
4. With your card issuer. Card scheme rules require that DCC be offered as a genuine, informed choice — not applied by default, not selected by staff without asking. If the cardholder wasn't offered the choice, that's a rules breach and worth raising. Realistically your bank will need the receipt and it will take weeks, so this is only worth pursuing on a large transaction.

Practical view: your leverage is at the counter in the first 60 seconds. After that, treat it as a lesson and check the next receipt.

Which cards avoid DCC entirely?

None. This is worth being straight about, because a lot of pages imply otherwise. DCC is triggered by the merchant's terminal reading your card's country of issue. No card can stop the prompt appearing, and no card removes your obligation to decline it. Anyone who tells you their card is "DCC-proof" is selling something.

What the right card changes is the size of what you're declining into. If you decline DCC on a card that itself converts at a marked-up rate plus a 2.25% fee, you've dodged 4–6% and kept 3–4%. If you decline DCC on a card that converts at the mid-market rate for a visible fee from 0.25%, you've kept almost nothing back.

There's also a second-order effect worth knowing. If you hold euros on a multi-currency card and pay a euro-denominated bill from your euro balance, there's no conversion happening at the point of sale at all — you're spending euros in a euro country. Some terminals will still offer DCC, and you still decline, but the transaction underneath is a same-currency payment with nothing to mark up.

The one-line version to remember at the till

Once that reflex is automatic, the remaining cost of spending overseas is your card's own pricing, which is a solvable problem: see the best card to use overseas from NZ for what each New Zealand bank charges, our travel money card comparison for the prepaid alternatives, and how much cash to carry by country for the part a card can't do.

Frequently asked questions

Should I pay in NZD or local currency when travelling?

Always local currency. Choosing NZD triggers dynamic currency conversion, where the merchant's payment provider converts at its own rate and keeps a markup of typically 3–6%. In most cases your bank still charges its foreign transaction fee on top, so you pay twice for one conversion.

What is dynamic currency conversion?

DCC is a service that converts a card transaction into your home currency at the point of sale rather than letting Visa or Mastercard do it. The merchant or ATM operator sets the rate and shares the markup with its payment provider. It's optional, and you should decline it.

How much does DCC cost?

Typically 3–6% of the transaction, and up to 7% or more at airport ATMs and tourist-district terminals. On a €84 dinner that's roughly NZ$5–10 extra. Across a NZ$4,000 trip where you accept it on everything, NZ$160–240.

Does declining conversion at an ATM cancel my withdrawal?

No. "Decline conversion" or "continue without conversion" means the ATM dispenses your cash in local currency and your own card issuer handles the conversion — which is cheaper. Your withdrawal proceeds normally.

How do I tell if I was charged DCC?

Look at the receipt. If it shows a NZD total from a foreign merchant, prints two currencies with an exchange rate between them, or carries wording like "cardholder currency" or "I elected to pay in NZD", you were charged DCC.

Can I get a DCC charge refunded?

Your best chance is immediately, at the counter — ask them to void the transaction and re-run it in local currency. After that, email the merchant with the receipt, or raise it with your card issuer, since card scheme rules require DCC to be offered as a genuine choice rather than applied by default. Success afterwards is patchy.

Which travel cards avoid dynamic currency conversion?

None can prevent the prompt — it's triggered by the merchant's terminal reading your card's country of issue. What a good card changes is the cost of the alternative you're choosing instead. Declining DCC on a card that converts at the mid-market rate for a fee from 0.25% leaves you paying almost nothing; declining it on a card with a marked-up rate plus 2.25% still leaves 3–4% on the table.
