Two more heavy vehicle certifiers have been suspended and the certification of 34 heavy vehicle towing connections revoked as lawyers review compliance cases for road safety issues.
NZTA tasked law firm Meredith Connell with assessing 850 cases of compliance after the transport agency failed to properly check the companies that certify vehicles as safe for road use.
Sixty-three of the 152 high priority cases have been reviewed and the tally of heavy vehicle certifiers suspended has risen to four after two more were pulled this month.
Timaru-based certifier Adam McFarlane was suspended on Monday, while Auckland-based Patrick Chu was suspended earlier this month, according to NZTA.
It followed the suspensions of Wellington-based certifier Dick Joyce in June and Nelson-based certifier Peter Wastney last year.
