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
You are unable to update your credit card expiry date using My One NZ. Instead, you need to register the updated card as a new credit card.
- Note: If you are paying by direct debit from a credit card, you'll need to update your direct debit credit card details as well.
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:
