As a result of the Customs and Excise Act 2018, which comes into effect on 1 October, certain importers can start using provisional values on import entries from 1 October if they have registered with Customs. In some cases, they will need to be approved first.
It takes 30 working days to process applications, so forms with all required documentation need to be lodged no later than 20 August 2018.
NZ Customs Service has produced an Importers Guide that explains the eligibility criteria and the registration process. The guide and registration forms are on NZ Customs website.
The Act education website has additional information about provisional values.
