Heavy vehicle certification information for customers – Patrick Chu

Patrick Chu recertification update for customers – 5 April 2019

On 5 April 2019, the NZ Transport Agency issued a safety alert regarding drawbars and drawbeams issued by Patrick Chu, explaining that all certifications of drawbars and drawbeams by Patrick Chu would be revoked. In line with ensuring safety comes first, and to minimise the impact on the heavy vehicle industry, several exemptions apply. This means only a small number of vehicles require immediate re-certification. To assist vehicle owners with re-certification, the Transport Agency is talking with heavy vehicle specialist certifiers regarding options to help ease pressure in the Auckland region. More information regarding this decision, including financial support, is available below.

Any urgent concerns can be directed to 0800 699 000.


The Transport Agency began investigating Auckland based heavy vehicle specialist certifier (HVSC) Patrick Chu in 2018 following safety concerns over the certifications issued for several heavy vehicle components.

The April 2019 revocation of certifications for drawbars and drawbeams on heavy vehicles follows a revocation in December 2018 related to towbars on heavy vehicles including small trucks, tipper trucks, motor homes and goods vans.
