This guide explains how to use the Area tool within a Network Update Request in NHVR Go. It shows you how to draw an area on the map to select many road segments at once and then apply approved, conditional or restricted access, or remove segments from the network. It also highlights how user-based security rules protect roads managed by other road managers or that are private or unmanaged.

1. In NHVR Go, open the relevant network and create or open a Network Update Request so the network is in Edit mode.

2. Locate the network management tools panel and select the Area tool. The Area tool is designed to change a lot of roads at one time in an area of your choice.

3. Decide on the area you want to change (for example around a town, industrial area or specific corridor).
​

4. Click once on the map to start drawing your area. Then continue clicking around the map to outline a polygon that covers all the segments you want to change.

5. Double click to complete the polygon. The Area tool selects all segments that are wholly captured within the area you have drawn.

6. Review the selected segments and note that:

a) If the area includes segments owned by another road manager, these will be identified and cannot have their access changed by you.

b) Segments that are private or unmanaged will also be noted so you can remove them from the selection or claim managership later if appropriate.

7. Right click within the selected area to open the context menu. The same context menu is used as for the Pan and Select tool.

8. In the context menu, choose the action you need for the selected segments you are permitted to manage:

a) Approve – grant access and add the segments to the network.

b) Add a Condition – apply a conditional access setting.

c) Restrict – apply a restricted access setting.

d) Remove – remove the segments from the network.

9. Check the cumulative number of segments and kilometres in the Network Update Request in the left-hand column as your area-based changes are added, to understand the size of the proposed change.

10. If needed, use the option to filter proposed changes by Access Type (for example Approved, Conditional, Restricted) so you can focus on reviewing specific groups of changes.

Use the Area tool when you need to change a lot of roads in one region; for detailed segment-by-segment work, the Pan and Select tool is usually better.

Only segments wholly inside the drawn polygon are selected. If you miss segments at the edges, redraw the area or supplement with the Pan and Select tool.

The system enforces user-based security rules. If your area includes segments managed by another road manager, private roads or unmanaged roads, you will see warnings or error messages and you cannot change access on those segments.

If you believe a segment in your area should belong to your organisation, use the Road Management tools to claim the road before trying again.

Remember that all changes proposed using the Area tool are part of the Network Update Request and will be reviewed by the NHVR Access Policy team for safety and Heavy Vehicle National Law (HVNL) compliance before they take effect.

Check your organisation’s internal guidance for how to document area-based changes (for example naming conventions or supporting justification).

If the Area tool or context menu does not behave as expected, or if you repeatedly see security errors on segments you manage, contact the NHVR using your usual support channels.
