How to cancel Kiwibank by mail
Collect the details you need
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Kiwibank can only act on a request it can match to an account.
Set out the request
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the Kiwibank account, stop every charge and reply in writing.
Post the letter
Post it by certified mail to Kiwibank in Wellington, New Zealand, using the exact address below, and note the tracking number.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Kiwibank charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Kiwibank, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
Open kiwibank.co.nz and look at the billing section: if a partner collects the payment, the request has to reach them too.
