The Topo50 map series provides topographic mapping for the New Zealand mainland and Chatham Islands at 1:50,000 scale.
At a scale of 1:50,000, Topo50 maps show geographic features in detail. They are useful for a wide range of activities such as local navigation by vehicle or on foot, locality area planning and study of the environment. Used by a wide variety of groups, Topo50 is the official topographic map series used by New Zealand emergency services.
To produce our Topo50 maps of the New Zealand mainland we use:
- the New Zealand Geodetic Datum 2000 (NZGD2000) – the coordinates of longitude and latitude
- the New Zealand Transverse Mercator 2000 (NZTM2000) projection – this is what enables the curved mathematical surface approximating the Earth to be represented on a flat sheet of paper.
To produce our Topo50 maps of the Chatham Islands we use the Chatham Islands Transverse Mercator 2000 (CITM2000) projection.
Topo50 sheet index
The sheet index shows you the areas covered by each map sheet, and their name and sheet code so that you can find and download the map you need.
Topo50 map sheet updates
Topo50 map sheets are updated based on many criteria including the availability of new aerial imagery, significant change in the topography and when the sheet was last updated.

Download a digital Topo50 map with Map Chooser
Use our Map Chooser to select and download a map for the area you want at 1:50,000. For bulk digital map orders, please contact us.
You can download these maps free as image files provided at 300 DPI, as either:
- a TIFF – shows the whole map including the legend and index much like a paper map
- a GeoTIFF – shows the spatial data area only (without legend or index), with georeferencing that automatically aligns your chosen map with adjacent maps within GIS systems. (You can download the Topo50 map legend (tif 859KB).
- Representation of a road or track does not necessarily indicate public right of access. For access rights, maps and other information, contact the New Zealand Walking Access Commission – walkingaccess.govt.nz
- 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 Closed tracks are defined as being no longer maintained or passable and should not be used.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.
