Below are some FAQs to help navigate through the changes that apply from 1 July 2021.
Why are we increasing prices?
2021 has been another year of change for us all. There have been both challenges and opportunities as we adapt and evolve to keep up with an ever-changing market. At New Zealand Post, we continue to be committed to providing you with sustainable, market-leading products and services now and for the future, in response to these changes.
To maintain our commitment, we need to continuously review our infrastructure and processes. As we upscale our business to reflect the changing market, we are also subject to a variety of changing cost components, including increased labour costs, investment in new technology and our continued focus on health and safety. While we’re always looking to reduce costs wherever possible, we have a responsibility to deliver a sustainable delivery service for New Zealand and we do need to review our prices annually.

No, however, you can use a KiwiStamp, which has a value of $1.50 from 1 July 2021, plus a stamp of a fixed amount to make up to the correct postage value. E.g. The cost to post a Standard Post Large envelope is $2.80, so you can use a KiwiStamp ($1.50) plus a definitive amount stamp of $1.30.
Unfortunately, use of the Priority Business Mail service has reduced greatly over the last few years, making it difficult to retain as a financially viable product. Therefore, we’ve decided to discontinue our Priority Business Mail services from 1 July 2021.
What can I do with my pre-purchased Priority Business mail envelopes after 1 July 2021?
You can continue to use pre-purchased Priority Business mail envelopes and pre-paid postage after 1 July 2021 as Standard Post. Our Standard Post service delivers mail across town and between major towns and cities in the usual, efficient timeframes.

Items sent using the International Air Small Parcel service are usually small in size, therefore we use actual weight to determine the postage however, airlines charge NZ Post for the space we use as well as weight.
To better reflect our costs, we are reducing the maximum dimension requirements of International Air Small Parcel, so light items with large volume will need to be sent via International Air parcel service.
