A person must not remove, erase, alter, deface, obscure, destroy or obliterate a VIN or chassis number.
A vehicle inspector must not issue a WoF or CoF to a vehicle with a removed, erased, altered, defaced, obscured, destroyed or obliterated VIN or chassis number.
However, if a vehicle can be appropriately identified Waka Kotahi will authorise the affixing or re-affixing of a new VIN.
These vehicles should be referred to a VIN issuing Agent (AA, Drivesure, Nelson Vehicle Testing Centre Ltd, VINZ, and VTNZ). They will inspect the vehicle and seek approval from Waka Kotahi to issue or re-issue a VIN plate.
