An investigation into an auto repair shop led to over 600 WOF's being revoked by Waka Kotahi.
Newmarket Auto Repairs has been suspended from MTA while an investigation is carried out into the company's lack of a certified inspector.
Motor Trade Association CEO Lee Marshall says a chance audit from the transport agency revealed this serious breach.
"The requirements are that warrants of fitness can only be issued by an authorised vehicle inspector and they need to be there and present and doing it. And we know from Waka Kotahi that this was not happening."
