Regulated entities use multiple systems managed by 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.

Portal enhancements

To date we have released 4 enhancements to the portal. Below we cover the functionalities included in each and what this has meant for entities.

In our most recent enhancement (April 2026) entities:

  • can apply for additional units post interim emissions value (IEV) issuance through the portal where they have an approved correction for a Register of Approved Vehicles (RAV) entry.
    • all applications must be supported by appropriate evidence or they won’t be accepted
    • will receive notifications to help them manage their NVES compliance activities.
  • can more easily manage their obligations by:
    • being able to upload documents in respond to a request for information (RFI) directly
    • accessing more information on unit transactions, emissions performance and unit expiration.

In our January 2026 enhancement:

  • we were able to issue interim emissions values (IEVs) and any associated units to entities from February 2026
  • entities were able to manage (transfer or extinguish) their units from February 2026
  • entities were able to self-manage their unit registry permissions through the portal dashboard. 

In our 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 account).

In our first release (September 2025) entities were able 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.

We are still developing the portal’s functionality. Another enhancement is planned for mid-2026. 

Portal user guide and video

You can download the NVES Portal user guide – Version 1.5 (Word 10.51 MB | PDF 2.95 MB) for guidance on accessing and navigating the portal.

NVES Unit Registry

The unit registry sits within the portal. The first units were issued in February 2026 when entities received their first interim emissions value (IEV) 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 emissions target 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 a fit and proper person (FPP) declaration.

Book your training to learn how to use the unit registry

Regulated entities that have opened a unit registry account can request on demand and one-to-one NVES Unit Registry ‘Initiator’ and ‘Authoriser’ Training. 

This 1-hour training session supports entities:

  • to use the unit registry to manage units
  • understand unit registry permissions
  • understand ey concepts related to trading NVES Units. 

Understanding how to use the unit registry is essential to trading and extinguishing units.

Unit registry permissions

There are 4 main permission types for unit registry accounts, they are:

  1. Registry viewer: a registry viewer can only view unit transactions and unit balances. If assigned this permission a user cannot hold any other permission.
  2. Transfer initiator: a transfer initiator can view the unit registry and initiate unit transactions for their account.
  3. 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.
  4. 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 a unit registry account

Apply

Regulated entities and their authorised users can apply to open a unit registry account. This application is done via the 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:

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.

Non-standard unit issuance: RAV adjustment or destroyed vehicle

Entities can apply for non-standard issuance of NVES units (additional units) after they have received their IEV for a performance year. This application can only be made if the entity has had a RAV adjustment made. Applications are made through the portal.

A RAV adjustment is determined after a RAV correction has been applied for and accepted. Further information about the RAV corrections process is here(Opens in a new tab/window)

Note: this application can only be used in limited circumstances (see eligibility criteria below). It is not related to the standard issuance of NVES units that occurs in February 2026 of each year once an entity beats the emissions target and receives an IEV below zero. 

Eligibility criteria

Non-standard issuance: RAV adjustment

An entity can only make this application if they meet all the following criteria:

  • their organisation has an active unit registry account
  • their organisation has made corrections to the NVES covered vehicles that were first entered on the RAV in a previous performance year (and they have been approved on the RAV with evidence)
  • these corrections occurred after their organisation's IEV for that year was issued
  • the corrections would have affected their organisation's NVES performance if they had been made before the IEV was released.

Non-standard issuance: destroyed vehicles

An entity can only make this application if they meet all the following criteria:

  • their organisation has an active unit registry account
  • their organisation has NVES covered vehicles that were entered on the RAV in a previous performance year but were destroyed and never provided to a consumer for the first time in Australia.

Entities will be notified once the regulator makes a decision about their application. This will be displayed under the ‘Notifications’ page in the portal.

If the decision results in additional units being issued, the units will be deposited into an entity’s unit registry account within 24 hours, and their unit holdings will be updated accordingly.
