VolumeMail is a cost-effective way to send 300 or more same sized mail pieces such as invoices, statements, company announcements and promotions within New Zealand, with a delivery target of three working days.

VolumeMail mail rates are based on the size, weight, overall addressing quality and total volume submitted per zone in an individual lodgement. To send your letters or documents by VolumeMail you need to ensure that you are sending 300 or more items of the same size and that each item is of the following dimensions:

  Minimum dimensions (height x length) Maximum dimensions (height x length) Minimum weight Maximum weight MInimum thickness Maximum thickness
Medium 88mm x 138mm 130mm x 240mm 3g 55g 0.3mm 6mm
Large 88mm x 138mm 165mm x 240mm 3g 75g 0.3mm 6mm

Mail must be lodged after 8am and before 5pm Monday to Friday (excluding weekends and public holidays).

Additional information about VolumeMail

Sending mail by VolumeMail

To send your letters or documents by VolumeMail, the following criteria apply within a single lodgement:

  • All mail items must have an approved PermitPost impression and NZ Post delivery and return address.
  • All mail items must be the same size, shape and within the same weight range.
  • All items must comply with current Postal Users' Guide and NZ Post standards for Postcodes.

Note: The minimum volume threshold and minimum dimensions must be met for each mailing customer. Mail from groups of customers may not be consolidated to achieve VolumeMail pricing.

For larger sized items, FlexiMail allows for a maximum thickness of 20mm.

Zonal Pricing

Zonal Pricing is a pricing structure that charges different prices for mail deliveries to different areas. Every New Zealand postcode containing delivery points has been allocated to one of four “Zones”; Zone A, Zone B, Zone C and Zone D. Each of these zones has a different price.

In addition to Zonal Pricing, a separate pricing tier applies to any items with invalid or missing postcodes. From 1 July 2020, all incorrect postcodes by Address Type (Urban, Rural, PO Box, Private Bag, etc.) or incorrect postcode mapping to City (and/or) Suburb including invalid or missing postcodes will be priced as Invalid Postcode (IPC). More information on Zonal Pricing terms and conditions is available under the VolumePost section of the Postal Users’ Guide.

Address Accuracy Percentage (AAP)

From 1 February 2021, AAP will replace SOA as the mechanism for pricing based on the overall address quality of the bulk mail lodgement. The AAP will be calculated on addresses in the Lodgement Data File based on Valid Postcodes only, to determine the applicable Pricing Tier (addresses with Invalid Postcodes will be priced separately).

AAP Pricing Tier AAP
Tier 1 95%+
Tier 2 90%-94.99%
Tier 3 80%-89.99%
Standard <80%/No AAP

How to prepare your mail for lodgement

Statement of Posting

A Statement of Posting (AR019N) form must accompany all lodgements or the lodgement will be held by NZ Post until we receive your form. Contact our National Contact Centre to have us send you a form. For help when completing the form download our Statement of Posting guide (PDF - 473KB).

When completing your Statement of Posting you’ll need to tell us your product code. Refer to the Bulk Mail Rate Card (PDF - 120KB) for the right code. NZ Post may correct any incorrectly completed Statement of Posting or lodgement slip, such as where the wrong VolumeMail code has been provided.

Electronic Lodgement Information

A Lodgement Data File (LDF) is required for all Bulk Mail lodgements (all bulk mail products/services). 

For Lodgements submitted through Lodgement Manager, a Statement of Posting is the output from creating a new Mail Order in Lodgement Manager.

In the process of creating the mail order you select Product characteristics including: Product, Size, AAP and upload the Lodgement Data File, from which the Zonal breakdown is derived. Once the mail order has been submitted in Lodgement Manager, no subsequent changes will be permitted, and the Statement of Posting is to be printed and attached to the physical mail for lodgement. A Statement of Posting form must accompany your physical mail lodgement or your lodgement will not be able to be accepted.

NZ Post will calculate the total cost of your lodgement from the LDF and the VolumeMail code applied to each item across the AAP pricing tiers and Zones, including records with Invalid Postcodes (IPC).

More information on Statement of Posting is available under the VolumeMail section of the Postal Users’ Guide.

Bulk Mail labels, letter trays and containers

Place your mail address side up and in letter trays so that the PermitPost impression is on the top right-hand corner of the envelopes, facing the front of the tray. If you are using reusable envelopes the PermitPost impression must be in the centre or top right-hand corner. Letter trays are available on application at your nearest NZ Post Mail Centre.

We have a container service for customers with lodgements exceeding 40 trays. All trays must be clearly and correctly labelled with the appropriate NZ Post label and must not weigh more than 12kg each.

Mailhouse lodgements: There are changes to Bulk Mail tray labels you need to be aware of. Tray labels will now be determined by the postcode line and product type. Please refer to the Bulk Mail tray label guide for more information. To find out more about these labels, please download the Bulk Mail desk chart (PDF – 3.8MB).

Business customer lodgements: For mail that is not lodged via mailhouses, simplified labelling requirements apply. Download customer labels for sorting (PDF - 93KB). Please print and complete these labels and attach these to the front of your mail tray.

Compliance requirements

To be eligible for VolumeMail product usage, lodgements must meet the specified requirements in the VolumeMail Product Specification section of the Postal Users’ Guide.

Non-compliance with the VolumeMail Product Specifications, Envelope Layout Standards along with the Addressing Layout Standards may result in the entire lodgement being uprated to a Standard rate product or No/ less than 80% Address Accuracy Percentage (AAP) price points, or the lodgement being returned at your cost. Note that delivery targets may be impacted by non-compliance with the VolumeMail Product Specifications, Envelope Layout Standards and the Address and Layout Guide.

To ensure non-compliance is kept at a minimum we encourage you to contact [email protected] or call 0800 501 501 for any mail pieces that you have questions on or for approval.
