Published on: 18/02/2026 07:00 AM

This page explains how to pay your bill using your credit card through the My One NZ App.

Before you begin

Confirm you are following the correct process by checking if you are a One NZ A,B or C customer .

This process is only compatible for One NZ A customers.

Surcharge Fee

A 1% (incl. GST) surcharge applies to online payments made with Visa, MasterCard, American Express, and JCB credit or debit cards for both automatic recurring and one-off payments.

This will be added to your total monthly bill and show as a single transaction on your card statement.

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