As such, the towing connection did not meet the required New Zealand Standard for heavy vehicle towing connections, and should not have been certified, it said. Engineering New Zealand said while no one was hurt in the incident, the consequences could have been serious. Wastney accepted the towing connection was not fit for purpose but provided no satisfactory explanation as to how and why these errors occurred, the organisation said. At the time, Wastney was one of Waka Kotahi NZ Transport Agency’s Heavy Vehicle Specialist Certifiers (HVSC). The disciplinary committee said Wastney’s departure from the standards expected of a chartered professional engineer was “at the higher end of the scale”.
