Being pre 89 you will just need the VIA (Import Approval) from DOTAR's. Would be a good idea to get it steam cleaned in NZ and checked for asbestos with whoever does it giving you a declaration stating its been steam cleaned and is free of asbestos. It will still be inspected by Quarantine on arrival regardless and what they will do/find will override any declaration you have been given by the NZ company and COULD lead to more treatment and costs (again, you might be fine and get a release also).. Its something to be aware of. Being over 30 years old you wont pay any duty but will still be up for GST and Quarantine charges of some sort.

I can recommend EDI Customs Brokers.. They have a specialist Automotive Logistics team who deal with this exact type of thing, and then you are dealing directly with the Forwarder/Customs Broker. If you have already found the car and dont need someone to source it for you also it will probably save you some $$$ as well...
