Update Vehicle Owner Details | Access to Guidance Notes - issued 16 September 2025

These Release Notes have been issued to certification authorities to clearly communicate the following changes to the SCV Register:

  • A change was made to the SCV Register that enables certification authorities to update the vehicle owner details against an existing certification. This change will also enable certification authorities to reprint warrant cards for vehicle owners, where a vehicle owner requests a reprint (due to loss, damage etc) but the original issuing certification authority has exited the regime.
  • A change was made to the SCV Register portal by providing a link that certification authorities can click to access guidance notes and other resources that have been issued to certification authorities since commencement.

Vehicles on the restricted register - issued 19 February 2025

This update is regarding the vehicles that are on the NZTA restricted list and do not show up on the SCV register.

You may have encountered a vehicle that does not yield a result on the SCV Register. That is due to the registered owner opting to make their information confidential. Therefore, it would be up to the registered owner to let you know this information as they are the one that has requested their information to be confidential initially.

When you come across a search with no results, the best option would be to send a direct email to the team that looks after the confidential vehicle register at NZTA.

Their email is conf@nzta.govt.nz. You can use this email to confirm the details as needed.

Use of generic green self-containment stickers - issued 30 January 2025

Green stickers are not part of the self-containment documentation issued by certification authorities under the ‘green warrant’ self-containment certification system and have no legal status.

We know that some certification authorities have been issuing green stickers for their own marketing purposes. However, we have been notified that the display of these stickers may be leading to some confusion, particularly with inbound tourists purchasing vehicles with these stickers.

Under the ‘green warrant’ system, a certification authority issues a self-containment certificate and warrant card if satisfied the vehicle meets the requirements in the Act and Regulations, and the person applying for the certificate has paid the levy. A green sticker is not a requirement of the self-containment certification.

The reason green stickers are not part of the self-containment certification documents is because it was considered that a generic sticker was ineffective as it showed no specific details about the certified vehicle. The risk is a generic green sticker could be placed on the exterior of any vehicle regardless of its self-containment facilities and certification status. Counterfeit stickers can easily be made as was evident with the blue self-containment sticker. The concern was that by continuing to use any type of sticker this problem would remain.

Action:

We ask that if you have been issuing green stickers, could you please now refrain from doing so. This will remove confusion and potential misrepresentation.

We would appreciate your support and cooperation on this request. This will benefit the sector as a whole and provide greater clarity for vehicle owners and the general public.
