Nine hundred people are being warned to get their cars checked because of concerns they might have been issued dodgy WoFs.
The concerns follow the suspension of vehicle inspector Oliver Wilson and his inspecting organisation Cambridge Auto Electric 2017 Ltd, in the Waikato.
Motorists with a current WoF issued from the store are being encouraged to get their vehicle rechecked. The Transport Agency will contact vehicle owners to advise them on recheck options, and vouchers will be provided.
The Transport Agency suspended the operator because of his inability to carry out Warrant of Fitness inspections in accordance with Land Transport rules and regulations.
"Most seriously, he failed to identify corrosion and seatbelt damage on a vehicle he was inspecting," the Transport Agency said.
