My One NZ | Add or Update a Credit Card

We are excited to help you easily register or update your Credit/Debit card on your My One NZ profile! You can conveniently do this through our user-friendly app or on our website. Enjoy seamless and secure transactions with just a few clicks!

Before you begin

Getting Started

Before you begin, please note that this process is not compatible with One NZ C accounts. You can easily check if you are a One NZ A, B or C customer .

Updating Your Card

The process of updating your credit card's expiry date is the same as adding a new card and you only need to do it once, you can use that same card for one off payments or to setup a Direct Debit.

Convenience Charge

A small convenience charge applies to all one-off credit card payments (even if your card is registered). This charge does not apply to direct debits from credit cards:

  • 1% charge for Visa and Mastercard
  • 2% charge for American Express

Card Storage and Limits

The 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 may take up to 3 days for a credit card registration to complete. Rest assured, your card information is stored securely on our credit card processor's encrypted database and is not stored on any of our systems.

Other Payment Options

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

Direct Debit Options

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