Regulated entities use multiple systems managed by us and the Department of Infrastructure, Transport, Regional Development, Communications, Sport and the Arts (the department) to meet their obligations under the New Vehicle Efficiency Standard Act 2024(Opens in a new tab/window) (NVES Act). These are:
- ROVER
- Register of Approved Vehicles (RAV)
- NVES Portal
- NVES Unit Registry.
We cover these systems below.
ROVER
ROVER(Opens in a new tab/window) is the administration system for the Road Vehicle Standards Act 2018(Opens in a new tab/window) (RVSA) and is managed by the department. Regulated entities and their authorised users use ROVER to:
- Submit and pay for a ROVER application.
- Monitor the progress of a ROVER application.
- Authorise other users to act on their behalf through an ‘authority to act’.
- Enable an NVES management permission.
- Access the NVES Portal.
- Receive and respond to requests for information on a ROVER application.
- Receive ROVER application decision notifications.
- Submit NVES-specific vehicles to the Register of Approved Vehicles (RAV).
Register of Approved Vehicles (RAV)
The RAV is managed by the department and sits within ROVER. It is an online publicly searchable database of vehicles that have met the requirements of the RVSA and been approved for provision to the Australian market.
All road vehicles must be entered on the RAV before being provided to the market for the first time.
Regulated entities enter NVES-specific data on the RAV as part of their obligations under the NVES Act, this data is used to calculate an entity’s interim emissions value (IEV) at the end of each performance period. The data entered on the RAV will become available in the NVES Portal for an entity to manage their compliance with the NVES.
Watch this video learn more about how to enter NVES-specific data on the RAV:
NVES Portal
We manage and maintain the NVES Portal (the portal) which is accessible via ROVER. It is a central online portal where entities can fulfil several functions to support their compliance obligations under the NVES. Entities access the portal by logging into ROVER(Opens in a new tab/window).
Entities can apply for an NVES Unit Registry (unit registry) account via the portal, which includes submitting a fit and proper person (FPP) declaration. An entity must be granted a unit registry account by the regulator before they can participate in unit trading.
In the first release (September 2025) the portal allowed entities to:
- apply to open a unit registry account, including submitting their FPP declaration
- view their NVES vehicle data as entered on the Register of Approved Vehicles (RAV)
- view their emissions performance over time (referred to as their rolling emissions value)
- view requests for information from us.
In the October 2025 enhancement, entities were able to access the new ‘Admin Centre’, in the portal allowing them to:
- update their Executive Officer details and secondary contact details for their organisation
- switch profiles (if they act on behalf of more than one regulated entity)
- update/give unit registry permissions to other users (only for a unit registry).
In our most recent January 2026 enhancement:
- we can issue interim emissions values (IEVs) and any associated units to entities from February 2026. Entities will be able to see them in the portal
- entities can manage (transfer or extinguish) their units from February 2026
- entities can self-manage their unit registry permissions through the portal dashboard.
Please note: As IEVs and units won’t be issued until February 2026, entities won’t have access to this functionality until these are issued. This is also pending successful approval of a unit registry account by us.
We are still developing the portal’s functionality, and more releases are planned throughout 2026.
Entities will need to complete and submit their unit registry account application in one session. We encourage entities to read the fit and proper person guidance before starting their application to help them complete and submit it in one short session.
NVES Portal user guide and video
You can download the NVES Portal user guide – Version 1.3 (Word 9.75 MB | PDF 2.5 MB) for guidance on accessing and navigating the portal.

NVES Unit Registry
The unit registry sits within the portal and will be made available from February 2026. The first units will be issued when entities receive their first interim emissions value (IEV) from February 2026 for the 2025 performance period.
We manage and maintain unit registry operations and access to ensure fair participation and to prevent misconduct. It is where units are issued, transferred and extinguished.
To receive units, entities need to beat the requirement for the performance period. To be able to receive, transfer and extinguish units, they will need to apply to open a unit registry account in the portal. Access to the unit registry is pending upon successful application and approval from the NVES Regulator and passing an FPP declaration.
Unit registry permissions
There are 4 main permission types for unit registry accounts, they are:
- Registry viewer: a registry viewer can only view unit transactions and unit balances. If assigned this permission a user cannot hold any other permission.
- Transfer initiator: a transfer initiator can view the unit registry and initiate unit transactions for their account.
- Transfer authoriser: a transfer authoriser can view the unit registry and authorise unit transactions created by a different user. They cannot authorise a unit transaction they make. They will then submit the authorised transaction to the regulator.
- Registry account admin: a registry account administrator can view the unit registry and add or remove users to the unit registry account.
These permissions allow entities and their authorised users to undertake a variety of actions. Users can hold more than one permission, unless they have been allocated as a ‘registry viewer’, in which case they cannot hold any other permission.
While one user may hold both transfer initiator and transfer authoriser roles, they cannot authorise the transfers they have initiated.
The roles can be assigned in the unit registry once the account has been opened.
Opening an NVES Unit Registry account
Apply
Regulated entities and their authorised users can apply to open a unit registry account. This application is done via the NVES Portal.
The application includes an FPP declaration. The applicant will need to fill out the NVES Unit Registry account application form, which requires them to make 2 legal FPP declarations. These are for:
- The regulated entity (as the legal person holding the registry account).
- Themselves (as the individual authorised to apply for the account).
The FPP questions relate to aspects of financial and company management, convictions, and behaviour. Answering ‘yes’ to any of these questions does not automatically result in an entity being ineligible to open a registry account.
Assess
Once submitted, we will assess all registry account applications. We may ask the applicant to provide further information to support their application.
Before we can decide to open an account, we have to be satisfied the entity and the applicant:
- has entered a covered vehicle on the Register of Approved Vehicles (RAV)(Opens in a new tab/window) from 1 July 2025
- does not already hold a registry account
- is fit and proper.
Decide
Based on our assessment of the application, we will decide whether to open a unit registry account for the regulated entity. We will notify the entity of our decision in writing.
Once an entity’s unit registry account is opened, the user with a ‘registry account admin’ role can provide access to additional authorised users. By granting access to other users, we expect the registry account administrator considers these users to also be fit and proper.
