VIRM: In-service certification amendment - effective 6 October 2021

Certification of cab modifications

Update to Table 3-1-2. Requirements for HVS certification.

Waka Kotahi has approved the following:

  • Provide short-term relief to vehicle owners now by granting a class exemption for all vehicles that have had uncertified cab modifications carried out before November 2018.
  • The initial class exemption is for five years and applies from 6 October 2021 to vehicles over 3.5 tonne.
  • The initial class exemption expires at the end of 30 September 2026 and may be amended, replaced, or revoked in accordance with section 168E(2) of the Land Transport Act 1998.

This means that people with vehicles granted the exemption can continue using their vehicle and obtain a Certificate of Fitness (CoF) for the duration of the exemption.

Vehicle inspectors are still required to check cab modifications as part of the standard CoF test. If they have any safety concerns (e.g. deformation, cracking, damage), they may refer the vehicle to a specialist certifier as part of their standard inspection practice.

The exemption is applied automatically and vehicle owners are not required to do anything.
