In July 2007, NZ Post introduced changes to their postcodes file, requiring customers to update their databases to enable access to bulk mail lodgment discounts. Simultaneously, the Postal Address File was released. The release of the PAF has brought significant benefits to the business community. These include more address databases, fasted/easier address capture and mail savings.

By July 2008, organisations will require a Statement Of Accuracy report on their data, with a minimum threshold of address accuracy achieved, in order to be eligible for bulk mail discounts. A Statement of Accuracy (SOA) is generated by SendRight certified software such as IQ Office.
