New Zealand car owners' reluctance to dump their old bangers is contributing to a growing national car fleet and making the roads less safe, the Motor Trade Association says.
The association estimated that in 2012, 138,000 passenger cars were scrapped, a fall of 9 per cent on 2011.
In the same period New Zealand's passenger car fleet grew by 0.9 per cent to reach a total of nearly 2.5 million vehicles, or 547 cars per 1000 people.
The most common date for New Zealand cars being registered was 1996, a factor that had remained unchanged since 2004, the association said.
Association spokesman Ian Stronach said it was the result of the large number of 1995 - 1997 registered used import cars which flooded into the country during the early 2000s. "Most of these cars are still being used and skew the age profile of our car fleet. Today, the average age of New Zealand's car fleet is 13.8 years; that is old by world standards and probably beyond the original design parameters of some models."
