I recieved the following email from Kiwibank, it has some pros and cons.
Con
From 4 November 2025, we’ll apply this fee to all international transactions, including transactions charged in New Zealand Dollars (NZD). This will be applied in the same way across our debit and credit cards.
For Kiwibank debit cards, the International transaction fee will reduce from 2.5% to 1.85% from 4 November 2025 which is in line with what this fee is on our credit cards today.
International transactions are typically transactions where the merchant or company processing the transaction is located outside of New Zealand. These transactions are either:
Payments processed overseas and charged in a foreign currency.
Payments processed overseas and charged in New Zealand Dollars (NZD).
Some examples of payments processed overseas and charged in New Zealand Dollars (NZD) include gambling, gaming, online accommodation booking and some streaming services.
Pro
from 4 November 2025, you’ll no longer be charged several of our everyday banking fees.
This includes the Visa Debit Card annual fee, and fees associated with using an overseas ATM. If you lose or damage your card and need to order a replacement, that’ll be on us too.
For our credit cards, we’re removing the Replacement card fee, and the Overseas ATM cash withdrawal fee.

This is a terrible policy from Kiwibank. How are you supposed to know whether the transaction that is priced in NZD is an 'overseas' processed transaction? It's impossible to tell isn't it? For example, buying an airline ticket from a foreign airline but departing in NZ (thus priced in NZD) , buying a streaming service subscription, getting a Didi or Uber?
