The Topo50 map series provides topographic mapping for the New Zealand mainland, the Chatham Islands, and offshore islands at 1:50,000 scale.

Along with the paper-based Topo50 map series, digital images of the maps are also publicly available.

Georeferenced raster digital images are provided at a resolution of 300 DPI. Georeferencing allows adjacent maps to be accurately and automatically aligned within GIS systems.

For more information, and a description of the georeferencing keys:

  • 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 - www.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 Closed tracks are defined as being no longer maintained or passable and should not be used.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 held in the data.

  • Contours and spot elevations in forest and snow areas may be less accurate.

  • Not all pipelines including both underground and above ground are held in the data or shown on the printed maps. For the latest information please contact the utility and infrastructure agencies

  • Permits may be required to visit some sensitive and special islands and areas. Contact the Department of Conservation to see if you need to apply for a permit.

Suitable for cartographic visualisation only. It was created by the interpolation of 20m contours with post-processing and filtering it is not suitable for terrain analysis.

This 8m Digital Elevation Model (DEM) was originally created by Geographx (geographx.co.nz) and was primarily derived from January 2012 LINZ Topo50 20m contours (data.linz.govt.nz/layer/768).

For a full description of the how the DEM was generated refer to this layer’s metadata.

This provides a polygon coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers:

This topographic coastline is the line forming the boundary between the land and sea, defined by mean high water.

Islands from the NZ Island Polygons layer that lie within the NZ Coastline and Chatham Islands areas (i.e. islands in lakes, rivers and estuaries) have been removed.

The GIS workflow to create the layer is:

  1. NZ Coastlines were converted from a polyline to a polygon using a polyline to polygon tool.
  2. The resulting coastal polygon was then used as an input into an erase tool and run against the NZ Island Polygon layer to remove all islands lying within the NZ Mainland and Stewart Island.
  3. This was then merged with the NZ Chatham Is island polygons (Topo, 1:50k) that have had the islands within the main island polygon removed, NZ Auckland Is Island Polygons (Topo, 1:50k), NZ Campbell Is / Motu Ihupuku Island, NZ Antipodes Is Island Polygons (Topo, 1:25k), NZ Kermadec Is Island Polygons (Topo, 1:25k), NZ Bounty Is Island Polygons (Topo, 1:25k) and NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k) layers using a merge tool.
  4. Lake Onoke from the NZ Lake Polygons (Topo 1:50k) layer and Te Whanga Lagoon from the NZ Chatham Is lagoon polygons (Topo, 1:50k) layer were then erased from the resultant polygon layer to include these two water bodies in the coastline definition.

For more detailed description of each layer refer to the layer urls above.

Note: This layer has been provided to enable potential users to identify the coverage of photography for Mainland NZ flown on behalf of the Crown between 1936 and 2005.

This layer shows the extent of each photograph taken. The NZ Aerial Survey Footprints, Mainland NZ, (1936-2005) polygons layer shows the extent of each survey undertaken.

The physical Crown Aerial Film Archive is managed for LINZ by WSP New Zealand. Most Crown photographs have been scanned and are available digitally from LINZ upon request. See the Crown Aerial Film Archive historical imagery scanning project for direction on how to access the digitised photos. The photos are not downloadable from the LINZ Data Service.

Photos not yet digitised by be ordered from WSP NZ. You will need to provide the survey, run, and photo number (values in the ‘SURVEY’, 'RUN', and 'PHOTO_NO' attributes) covering your area of interest. WSP NZ will be able to provide information about the cost of providing images in various formats. Contact them at WSP Photo Sales.

The New Zealand Aerial Mapping photo archive has been aquired and added to the Crown Aerial Film Archive. These images will also become available from LINZ once digitised or may be ordered from WSP NZ. Historic Aerial Photos, Survey Footprints, NZAM (1939-2008) shows the extent of each survey undertaken.
