  5. Pass a theory test conducted by us.
  6. Pass a practical test conducted by us.
  7. If your application is successful, we’ll appoint you as a vehicle inspector.

Prerequisites to apply

Driver licence prerequisites

You must have a current and correct class of driver licence to drive the vehicles you want to inspect.

You must drive to the conditions imposed on your licence.

If you have a learner or restricted motorcycle licence you can only inspect motorcycles that are LAMS approved.

LAMS approved and prohibited motorcycles

Note: Where a class 5 vehicle does not have to be driven by the vehicle inspector who is conducting the inspection, the minimum class of licence to be held is a class 4 licence.

Overseas licences

If you apply with an overseas licence you must also send us:

  • a clear colour copy of your overseas licence (all sides/pages)
  • your international driving permit (if you have one).

Be aware that if you’re driving in New Zealand with an overseas licence, once you’ve been in New Zealand for more than 12 months (for classes 2-6), you can’t drive on your overseas licence anymore. For class 1 (car) licences, until 31 October 2026, once you’ve been in New Zealand for more than 18 months,  you can’t drive on your overseas licence anymore. You must get a New Zealand licence.

You might need to pass a theory and/or practical test to get a New Zealand licence.

If you need to pass a theory and practical test, you’ll get a New Zealand driver licence with a supervisor condition. This means you must have a supervisor with you at all times while driving, even when inspecting vehicles (until you pass your practical test).
