Proposed changes to the way vehicles are tested in New Zealand are raising concerns over safety.
The Government has outlined four major changes to the warrant of fitness tests vehicles must go through to prove they are roadworthy.
Among the changes considered are annual inspections for vehicles newer than 12 years old instead of the current timeframe of six months.
The Government is also considering a first inspection at three years, then annually, as well as warrant inspections based on distance and change of ownership.
AA spokesperson Mark Stockdale said the changes are likely to be popular amongst motorists.
"If there's ways that we can actually maintain or even improve safety while reducing costs to motorists then I think that's something that motorists will be very keen on."
Around 5.5 million warrants of fitness are issued every year but it is estimated 10% of vehicles do not have one.
"The most common reasons vehicles can fail a warrant of fitness are defective lights, brakes and tyres," said Stockdale.
At least 2.5% of vehicle crashes are caused by faults that should have been picked up by warrant inspectors.
But the Government says it is not about money before safety.
"Overseas where they do less inspections but they do other things, safety actually can go up," said National MP Simon Bridges.
However, VTNZ Chief Executive Mike Walsh said that position was "flaky".
"Commonsense says that vehicles get older and they travel more miles, they'll get more faults," said Walsh.
Compared to other countries, New Zealand has one of the most frequent inspection regimes in the world.
Vehicles are typically inspected every 6000 kilometres in New Zealand, whereas in the UK they are tested every 19,000km and in Germany every 32,000km.
Motorists have six weeks to have their say on the proposed options and any law changes will be made at the end of the year.
