System description
Each month, New Zealand Transport Agency (NZTA) sends MBIE, by SEEMail online transfer, a file of all individuals or entities who have sold more than six vehicles in a 12 month period. NZTA maintains a record of registered traders (through MBIE providing monthly registered trader updates to NZTA) so that transfers to MBIE exclude individuals or entities already registered as Motor Vehicle Traders. 

MBIE manually compares the NZTA data with its Motor Vehicle Traders Register to identify unregistered individuals and companies. Before MBIE issues a s.181 notice to an individual[1] whom it believes should register as a motor vehicle trader, it requests the following additional information from NZTA in relation to each vehicle:

  • registration plate number
  • VIN and chassis number
  • details of sale/transfer of ownership (e.g. name and address of seller and buyer)
  • odometer reading.

If, following the review of the extra information received, it appears that the individual or entity should be registered, MBIE sends a s.103 notice (notice of adverse action) requesting registration within 10 working days, or an explanation to the Registrar about why the individual or entity does not need to be registered.  Failure to respond to the notice may result in a referral to the Registrar’s National Enforcement Unit for possible prosecution under the Motor Vehicle Sales Act.

MBIE also access the file from NZTA to conduct manual look-ups if a complaint is received. The person who performs the information matching programme is authorised to perform the look-up on behalf of all other investigating staff. A privacy register is maintained to record details of each access to NZTA data for complaints purposes, and a summary report of this activity is provided to this Office.
