VIRM: Heavy vehicle specialist certification memo incorporation amendment – effective 9 April 2018

In consultation with a key HVSC industry group, the NZ Transport Agency has been working to complete the incorporation of HVSC memos into the HVSC vehicle inspection requirements manual (VIRM). This has been done to centralise sources of information for your ease of access and to allow for a simpler change process going forward. This work is now complete and as of Monday 9 April 2018 all HVSC memos are rescinded and the VIRM amendment will go live.

Many memos now take the form of technical bulletins, while others have been incorporated into the main body of the VIRM under the various sections. While the memos have been incorporated into the VIRM, there hasn’t been any policy or procedural changes

All current certifications (LT400s) referencing the memos will remain valid for the life of the LT400s validity. Starting from 9 April 2018, any references must now be to the relevant section or technical bulletin.

If you have any concerns with the changes made or would like to propose additional changes, please contact us at vehicles@nzta.govt.nz. The Transport Agency will be reviewing the changes in six months, and any feedback received will be considered as part of the next amendment.
