Important information for reading your Topo50 Map
Representation of a road or track does not necessarily indicate public right of access. For access rights, maps and other information, contact Herenga ā Nuku Aotearoa, the Outdoor Access Commission
- The Department of Conservation and other agencies should be contacted for the latest information on tracks and back country huts. Closed tracks are defined as being no longer maintained or passable and should not be used.
- Not all aerial wires, cableways and obstructions that could be hazardous to aircraft are shown on the map.
- Contours and spot elevations in forest and snow areas may be less accurate.

Private and public roads
Our topographic maps and data are an official record of New Zealand’s landscape, and we have a responsibility to show both private and public roads and tracks. This is necessary information for emergency services who may need to use private roads and tracks to gain access to an emergency scene, and is also important for capturing change to our landscape over time.
Roads and tracks shown on our maps are not necessarily accessible to the public. This is stated on the maps and in the metadata for the datasets used to produce them.
It is not possible to accurately show which roads and tracks are public and which are private. This information can change often, and in some cases ownership or access to a road or track is not clear.
