Receiving mail by International Business Reply

The first step is to apply for a NZ Post PO Box or Private Bag (if you currently do not have one) for the International Business Reply responses to be sent to. You also need to have a NZ Post Account to use this service.

The second step is to apply for a NZ Post credit account (not your PO Box account number starting with 6 or your Courier account starting with 9) for the International Business Reply mail items to be charged to.

If you do not have a NZ Post credit account, please download the Application for Credit and NZ Post Direct Debit  and email with an International Business Reply application form as PDFs to [email protected]

The third step is to apply for an International Business Reply authority number by completing the International Business Reply application form (PDF - 41KB) and including an example of your response device. You cannot have an International Business Reply authority number that is already being used by someone else, or if NZ Post decides it isn't suitable.

The fourth step is to use the International Business Reply layout guide below to design your response device. When your format has been approved, you can have your printer print your International Business Reply authority number beneath the Economy, or Par Avion indicator at the top left corner of your response

Once you have completed these steps you can include your pre-printed International Business Reply card or envelope with your mail.

Format requirements

Your card or envelope design must meet the following requirements:

  • Your response device must meet the above layout guidelines so that overseas postal administrations recognise that no postage is required
  • Response devices must be addressed to a NZ Post PO Box or Private Bag address in New Zealand. Street addresses are not accepted
  • Your response can be either a card or an envelope.

We recommend that you talk with us about your International Business Reply card or envelope design prior to printing. You can have your layout approved by emailing it to [email protected]. We’ll be in touch if we have any queries or need to suggest a change to your design. If everything is ok, we’ll let you know that your design has been approved.

As soon as your International Business Reply layout design is approved, you can go ahead and have your cards or envelopes printed.

Apply authority word or number

Complete and submit the International Business Reply application form and email it to [email protected] or post using the FreePost address on the form.

Cancelling an authority number

You are able to use your International Business Reply authority number until it is cancelled, either by yourself, or NZPost.

Please inform us in writing by sending an email to [email protected] if you wish to cancel your International Business Reply authority number.

NZ Post reserves the right to cancel your International Business Reply authority number at any time.

Once your International Business Reply authority number is cancelled, please inform your customers that the number is no longer to be used. You’ll continue to be charged for any business mail received using your International Business Reply authority number after it has been cancelled.

Notifications and payment

When you receive International Business Reply responses, we’ll leave your responses in your NZ Post PO Box or Private Bag and we will charge the payment to your NZ Post Account.
