In September 2016 the NZ Transport Agency (NZTA) introduced new rules requiring electronic safety components such as airbags, sensors and wiring be replaced in water-damaged light vehicles. Previously, only items below the water line had to be replaced.
The changes applied to vehicles damaged in New Zealand as well as imported vehicles. NZTA said there had been concerns about the quality of repairs, and cases where people had masked or misrepresented water damage levels.
MTA dealer and mediation specialist Tony Everett said those tougher standards would make it much more uneconomical for dealers to bring in write-offs from Australia to sell.
"I guess that is what it was trying to do – set in place a barrier. With a low value car, you just wouldn't bother."
Everett said the MTA welcomed the review of information disclosure requirements, having previously raised the issue with the former Government.
However, data was still lacking about damaged vehicles coming from countries other than Australia. The NZ Transport Agency has previously tried to get similar information from Japan, where most imports come from, but a write-off register does not exist there.
In May 2016 Trade Me announced it was requiring disclosure of write-off status for all motor vehicles listed on its website, saying it was concerned about safety.
"Consumers need to know the accurate history of a vehicle," Trade Me said.
"We're aware of cases where consumers have paid the same price for vehicles that have been through the statutory write-off process as they would for vehicles that have not suffered significant damage."
