The NZ Transport Agency has begun contacting about 10,000 Kiwis, whose cars may not have been properly checked during their regular Warrant of Fitness inspection.
Law firm Meredith Connell is reviewing the cases involving cars that may not have been checked properly and managing partner Steve Haszard says owners will be able to have their vehicles "re-checked free of charge via a Transport Agency voucher".
He said Meredith Connell had completed a review examining the "most urgent" cases.
"Significant progress has been made and reviews completed of the most urgent files where public safety was potentially at risk," he said.
"We have provided recommendations to the Transport Agency. On the basis of these recommendations and following legal processes the Transport Agency is stepping up enforcement action for non-compliance across all regulatory areas for which it has responsibility."
