A former top police officer says the road toll will climb within a few years because of "narrow-minded" changes to the warrant of fitness regime.
He also says police officers aren't mechanics and shouldn't be getting under cars to check vehicles' warrant compliance.
Former head of the Waitemata District serious crash unit sergeant Stu Kearns spoke with the Herald to outline his concerns about changes to New Zealand's warrant of fitness regime that will see cars registered after January 1, 2000, requiring a yearly check for a WoF instead of every six months.
New cars will undergo an initial inspection but will not require a WoF for a further three years.
Mr Kearns, who stepped down in 2010 ending a 28-year career as a traffic cop, said it was naive to compare New Zealand and other countries' warranting systems when implementing the changes as most other countries had far superior driving behaviour records and very few accepted secondhand Japanese import cars.
