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

Providing our service in an efficient way is very important to us. Regularly reviewing how we do things is key to continuous improvement, so our service is resilient and fit for your business needs.

Like many businesses, we’re experiencing rising costs and other pressures. It’s our responsibility to continually deliver commercial returns and a sustainable delivery service for New Zealand. Part of that means that we need to review our prices each year, so that we can make the right adjustments to continue growing, whilst building long-term financial sustainability.

The following Standard Mail products will have a price increase that will apply from 1 July 2026.

Standard Mail 

• Standard Mail letter prices across New Zealand will increase by 70 cents (incl. GST). This means that the medium sized letter will increase to $3.60 (incl. GST) and the large and oversize letters will also increase by 70 cents to $4.90 and $6.20 respectively. 

• ReplyPaid envelopes non-approved format will increase to $3.60. ReplyPaid Medium – approved format will increase to $3.50.

Please refer to the Standard Mail Rate Card (PDF 49KB) for pricing. New prices will apply from 1 July 2025.

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.

To find out what you can do to give your letters the best chance of a smooth journey, visit Bulk Mail to see guides and more information. 

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.
