Statement of Accuracy

To qualify for Bulk Mail discounts by providing an 85% Statement of Accuracy for your customer addresses, find a certified provider or purchase SendRight software to develop your own application in-house.

Or were you after: 

A Statement of Accuracy is an electronic certificate showing the percentage of addresses in your address mailing list or database that are valid matches against the New Zealand Post Postal Address File (PAF).

The PAF is New Zealand Post’s definitive file of New Zealand postal addresses within our delivery network. It includes around 1.8 million delivery addresses and is an electronic file of data which can be licensed directly from New Zealand Post.

Having an 85% accuracy rate for your customer addresses means New Zealand Post can deliver your mail efficiently and accurately. It also reduces costs to your business for things like returned mail.

Valid for 12 months, your Statement of Accuracy requires an identification number and percentage rating which must be declared against all Bulk Mail lodgements on a Statement of Posting, i.e. an AR19N or Lodgement Manager Manifest. You must renew your Statement of Accuracy every 12 months in order for it to remain valid, otherwise you will not be eligible for Bulk Mail rates

Prices for Statement of Accuracy

A threshold of 85% applies to be eligible for Bulk Mail rates on the total lodgement. If you have a Statement of Accuracy of less than 85%, the difference will be charged at an applicable Letter Domestic Product (LDP) rate.

For example, where a Statement of Accuracy of 80% is achieved, 5% will be charged at the LDP rate. We’ll also add a Statement of Accuracy prefix to your original product code. See example below:

Original Product Code Statement of Accuracy % Problem The code that will appear on the invoice How the non-conformance rates are applied
VP1MS 75% Statement of Accuracy less than 85% SOAVP1MS Unit rate on the bill is based on 10% calculated at LDPM rate (85% - 75% = 10%) and the 90% balance at Bulk Mail rates (100% - 10% = 90%)

  • Community Boxes

Statement of Accuracy reconciliation takes place each month. This is where an automated check compares the Statement of Accuracy data received from the Data Solution Providers against declarations made on the Statement of Posting forms.
