Minister of Transport Phil Twyford said the agency had been "going through a massive change process", with its compliance work in the issuing of vehicle Warrant of Fitnesses under review.

109 of the affected roles came from the former Clean Car Discount, Climate Emergency Response Fund, and Let's Get Wellington Moving projects, which had been cancelled by the National-led coalition government.

[21] NZTA stores registration, licensing and warrant of fitness details for any road-registered vehicle within New Zealand, including cars, motorbikes, trailers, trucks and earthmoving or agricultural machinery.

Any member of the public can query NZTA's database by making a request using the licence plate or VIN at an NZ Post outlet, or by using a vehicle checking website.
