Currently an annual SOA assessment is required for each customer to lodge Bulk Mail with New Zealand Post.
From 1 July 2020, the requirement to submit a Lodgement Data File (LDF) will apply to all Bulk Mail services to support the changeover to the new AAP (Address Accuracy Percentage) process, to be effective 1 February 2021.
The AAP process replaces the SOA process on 1 February 2021. The AAP will be calculated only on records with valid postcodes (records charged the IPC price will be excluded from the assessment). “AAP” columns will replace the “SOA” in the rate cards from 1 July 2020 but SOA will still apply until 31 January 2021.
