This guide explains how to open an existing vehicle network in NHVR Go in view-only mode. It describes what you can see in the left-hand information panel and on the map, including default safety-related layers. It also shows how to adjust the panel and layers so you can focus on the network information you need.

NHVR Go (NHVR Portal) account with Road Manager access.

Access to Access management in NHVR Go.

The network has been identified in the Vehicle networks table and appears in your list (see “Searching for an existing network”).

1. Open NHVR Go in your browser and log in with your Road Manager account.

2. From the menu, select Access management, then select Vehicle networks so the Vehicle Networks table is displayed.

3. In the Vehicle networks table, locate the network you want to view.

4. Click the hyperlink under Vehicle Network Name for that network. This opens the network in view-only mode.

5. Review the left-hand panel:

a) Read the key network details shown for the selected network.

b) Use the subscribe link if you want to be notified of changes to this network (for example, when the map is updated).

6. In the left-hand panel, select the Access tab to see access-related information:
a) Open the Gazette Notice link to view the legal instrument for the network.
b) Open the Operator’s Guide link for operator-facing guidance.
c) Confirm the status of the Access Instrument for the selected network.
​

7. If you need more space for the map, collapse or reduce the left-hand panel using the on-screen icon so the map can be viewed in full screen.

8. Review the network on the map on the right-hand side of the page:

a) Confirm that the highlighted network correctly shows the roads included in the access instrument.

b) Zoom and pan the map as needed to inspect particular location.

9. Check the default layers that are automatically included in this view:

a) Open the layers drawer (bottom left-hand corner of the map).

b) Note that certain safety-related layers are turned on by default (for example rail crossings, height clearances, construction, boundaries, swept path and safety zones).

c) Turn individual layers on or off by ticking or unticking them in the layers drawer.

10. If you will use this map often, add it to your favourites list so you can return to it quickly from the home page.

View-only mode is for reviewing network information. Any changes to roads or conditions must be made through a Network Update Request and are subject to NHVR Access Policy review against safety and the Heavy Vehicle National Law (HVNL).

If you cannot see the information you expect in the left-hand panel, check that you have the correct network open and that the panel is not collapsed.

If the map looks cluttered, turn off non-essential layers in the layers drawer and keep only the safety or reference layers you need for your task.

Subscribing at the network level notifies you of changes to that network only; to receive updates for all networks in a state, subscribe at the state level from the Networks view in the National Network Map.

Check your organisation’s internal guidance on how networks should be reviewed and who is responsible for subscriptions and favourites.

If the network or layers do not appear as expected, contact the NHVR using your usual support channels.

Use NHVR training materials or road manager communications for more examples of how to interpret the left-hand panel and network display.
