The NZ Transport Agency has taken immediate action to suspend a vehicle inspector on Auckland's North Shore after a review.
Glenfield inspecting organisation World Motors and its vehicle inspector Sun-Jin Kim has been suspended after an unauthorised staff member was observed inspecting customer vehicles.
"Subsequently, Mr Kim has admitted to not using the required equipment to test brakes and lights. He also failed to correctly inspect seat belts," NZTA said.
"We are unaware of specific concerns relating to individual vehicles, however due to the concerns around World Motor's inspection practices there is a strong possibility that some vehicles may have been incorrectly passed.
"For this reason, we strongly encourage people who have a current warrant of fitness issued from World Motors to get their vehicle rechecked."
