Business sending pricing and product changes from 1 July 2026 ​​ - questions and answers 

Like many businesses, we continue to see rising costs, amongst other pressures. We remain focused on strong network performance, processing capacity, and dependable delivery for your customers. 

It is our responsibility to continually deliver commercial returns and a strong, reliable and more sustainable delivery service for New Zealand, and we do need to review prices regularly and adjust accordingly.  

While we are always looking for ways to deliver our service more efficiently, cost increases are being felt across our business. We’ve worked hard internally to manage and reduce these costs, and where possible, we’ve limited increases across products where we can.  

The prices for all domestic Courier and Express services will increase on 1 July 2026. As an NZ Post account customer, you can expect to receive your notification of the price increases by letter or email in May 2026. If you haven't received these details, please contact us.

Zonal Pricing is our pricing structure that applies to all Bulk Mail products and charges different prices for mail delivered to different areas. Four pricing zones (A-D) are defined by postcodes and each zone has a different delivery price. Zonal Pricing applies to AdCard, FlexiMail, VolumeMail and Publication Mail products. A fifth tier (IPC) applies to items sent with an invalid postcode.

You can use the Bulk Mail rate card and Zonal Pricing information to estimate the cost of postage for a lodgement. We have developed a system for files to be submitted electronically by saving but not submitting the file, allowing you to determine postage costs under the Zonal Pricing structure. Once you have submitted your lodgement, the saved file can be deleted.  

AAP is a price differentiator on the Bulk Mail Rate Card (PDF 61KB). All Zonal (A, B, C & D) pricing is differentiated by AAP tiers. However, all mail items with missing or invalid post codes will be charged at the same IPC price relative to the product and size rather than the AAP tier.
