Mr Brock said about 30 per cent of customers did the bare minimum in terms of car safety.
"The high-end customers - no problem, and if it's serviced regularly as well, that's fine.
"But the budget customers are a bad idea because they just want to get away with everything."
The proposed options include four alternatives to streamline the Warrant of Fitness scheme and changes to the vehicle registration programme.
Currently, vehicles must be inspected every six months if older than six years. Newer vehicles are inspected annually.
At a cost of about $50 per inspection, Kiwis are forking out nearly $250 million in inspection fees each year.
Proposed changes include tougher testing standards, but less frequent inspections and the introduction of demerit points penalising those who do not comply with WoF safety standards. A further seven changes to vehicle registration are included in the document, plus new options for the Certificate of Fitness and transport licensing systems. The AA says the changes could bring New Zealand into line with the rest of the world.
"New Zealand is the only country in the world that requires most vehicles to undergo a safety inspection every six months," spokesman Mark Stockdale said.
Associate Transport Minister Simon Bridges said about $245 million was paid in WoF inspection fees by Kiwis each year.
"And the time spent getting a WoF is estimated as worth $100 million. But it is unclear whether this results in fewer crashes caused by vehicles."
