The second step is to apply for a FreePost authority number or word. You cannot have the FreePost authority number or word if that number or word is already being used by someone else or if New Zealand Post decides it isn’t suitable.
The third step is choosing which type of FreePost layout you would like to use. You have the option of either (1) an approved format, which may make you eligible for a postage discount or (2) a non-approved format.
Once you have completed these steps you can include an approved pre-printed Freepost envelope with your mail, or promote your authority number/word on your stationery, marketing material and business letters. Your customers can then write this on a blank envelope before sending mail to you.
Approved format FreePost envelopes
To meet the approved format layout, your envelope design must meet the following requirements:
Have your FreePost authority number written on one line and located in the sender address/company logo area
Display your business name and New Zealand Post PO Box or Private Bag address
Have the address printed using black or dark blue type 3 FIM indicia
Have the FreePost and New Zealand Post button impressions printed using black or dark blue ink
Be a non-window envelope only.
Have the address panel bars(located at each end of the envelope) between 2mm and 5mm wide
Meet the maximum dimensions, thickness and weight requirements to receive the approved format price (130mm high x 235mm long x 6mm thick and 500g in weight). The minimum envelope dimensions for approved format FreePost envelopes are 92mm high x 165mm long.
We will check your FreePost responses to see if it meets these requirements. If it doesn’t, we may not be able to accept or deliver your mail.
We recommend that you talk with us about your FreePost envelope design prior to printing. You can have your layout approved by emailing it to us at [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 FreePost layout design is approved, you can go ahead and have your envelopes printed.
Non-approved format envelopes
A non-approved format means that you can be creative with your envelope design, or allow your customers to handwrite their reply mail. Non-approved envelopes are not eligible for the approved format discount.
A non-approved FreePost response layout may look like this:
New Zealand Post reserves the right to cancel your FreePost authority number or word at any time.
Once your FreePost authority number or word is cancelled, please inform your customers that the number or word is no longer to be used. You’ll continue to be charged for any business mail received using your FreePost authority number or word after it has been cancelled.
