My One NZ | Add or Update a Credit Card

This article explains how you can register or update a Credit/ Debit card to your My One NZ profile via the app or through One NZ website.

Before you begin

  • This process is not compatible with One NZ C accounts.
  • Find out how to check if you are a One NZ A, B or C customer .
  • You only need to update your card once regardless if it is used for one off payments or direct debit, as it will automatically be updated
  • The process of updating the credit card expiry date is the same as adding a new card.

Convenience charge

A convenience charge applies to all one-off credit card payments (even if your card is registered. It doesn't apply to direct debit's from credit cards):
  • 1% charge for Visa and Mastercard
  • 2% charge for American Express

About card storage and limits

My One NZ app can store up to 10 cards per Primary connection.
  • A credit card can be re-registered against a billing account up to 5 times per 12 months
  • It can take up to 3 days for a credit card registration to complete.
The card information is stored securely on our credit card processor's encrypted database and is not stored on any of our systems.

If you need to make a one-off payment check our Pay by credit card through the app article.

You should consider setting up a direct debit instead so you don't have to worry about paying your bills manually in the future:
