The Place Names Gazetteer contains official and unofficial place names under the jurisdiction of the New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB). Official place names are those that have been assigned, altered, adopted, approved, and validated under the NZGB Act 2008 or through other statutes that assign official names, for example, Treaty settlement legislation. Unofficial place names are those that have not been processed under the NZGB Act 2008 or through other relevant statutes.

Data is extracted from Land Information New Zealand’s (LINZ) ‘New Zealand Gazetteer of Official Geographic Names’, which is maintained by the NZGB Secretariat.

Geographical coverage encompasses New Zealand, the Ross Dependency of Antarctica, and the Continental Shelf of New Zealand.

The NZGB has naming jurisdiction over:

• natural features such as mountains, peaks, valleys, glens, forests, lagoons, swamps, creeks, streams, rivers, fords, lakes, glaciers or ice features, bays, islands or harbours (including man-made features of the same type)

• railways or railway stations, but not railway features such as marshalling yards, transfer sites, or track point locations

• places, i.e. cities, towns, villages, sites, areas, or similar places, including suburbs and localities

• undersea features

• Crown protected areas

• Districts and regions (altering only if requested by the local authority)

Each name is provided with a location represented by a point. More complex geometry (e.g lines for rivers or areas for suburbs) is not currently available.

Each geographic feature has one or more place names associated with it. Place names usually comprise two components – ‘specific’, being for the proper noun, and ‘generic’, being a description of the geographic feature type.

Information provided for each place name may include: name; name status (whether official or unofficial); geographic feature type; authority by which an official name became official; district within which the name is located; geographic location; reference information; history/origin/meaning; and additional notes. Not all information is available for all names.

Positional accuracy is generally the same as 1:50K mapping. Information accuracy reflects information at the time of original capture.

The NZ Imagery Survey Index dataset provides an index to all orthophoto index tiles found on the LINZ Data Service. Each record in the dataset provides both a geometry of the maximum extent of the orthophoto index, as well as all attributes found in each index tile. This dataset therefore provides information to assess orthophoto coverage and metadata across the entire country.

Please refer to the NZ Aerial Surveys Data Dictionary for detailed metadata and information about this dataset.

The imagery data referenced by this dataset is available on the LINZ Data Service.

The NZ Elevation Survey Index dataset provides an index to all LiDAR derived elevation datasets found on the LINZ Data Service. Each record in the dataset provides both a geometry of the extent of the elevation survey, as well as useful metadata attributes. The extents are derived from the maximum extent of DEM and DSM coverage and consist of full NZTopo50 1k tiles, even where a tile is only partially covered with data. These extents only provide a rough indication of corresponding point cloud coverage which can be quite different for some elevation surveys.

Please refer to the NZ Aerial Surveys Data Dictionary for detailed metadata and information about this dataset.

The elevation data referenced by this dataset is available on the LINZ Data Service.

The NZ 50k Tile Index dataset provides a 1:50,000 scale base index for larger scale indexes used for aerial imagery and LiDAR datasets. This index is different from Topo50 Map Sheets in that there are no overlapping index polygons in this dataset. This index also expands further into the sea to support future mapping in coastal areas and encompasses all offshore locations up to 50m in depth. The dataset includes a map sheet code consistent with those from Topo50 Map Sheets, and an attribute for each tile to show whether there is a corresponding Topo50 map sheet with matching location coverage.

The NZ 1:10k Tile Index dataset provides a 1:10,000 scale index for aerial imagery and LiDAR datasets. Along with the 1:1k and 1:5k datasets, this
1:10k tile index is part of a collection of indexes which are referenced to the NZ 1:50k Tile Index dataset.
Like the NZ 1:50k Tile Index, these larger scale indexes support mapping of NZ mainland and coastal areas up to 50m in depth.

The dataset includes the following attributes:

index_tile_id : Unique identifier for the NZ 1:10k Tile Index table.
sheet_code_id : The corresponding sheet code of the NZ 1:50k Tile Index.
scale : The map scale of the index tiles.
tile : The combination of the row and column numbers of the index tiles.

The NZ 1:5k Tile Index dataset provides a 1:5,000 scale index for aerial imagery and LiDAR datasets. Along with the 1:1k and 1:10k datasets, this
1:5k tile index is part of a collection of indexes which are referenced to the NZ 1:50k Tile Index dataset.
Like the NZ 1:50k Tile Index, these larger scale indexes support mapping of NZ mainland and coastal areas up to 50m in depth.

The dataset includes the following attributes:

index_tile_id : Unique identifier for the NZ 1:5k Tile Index table.
sheet_code_id : The corresponding sheet code of the NZ 1:50k Tile Index.
scale : The map scale of the index tiles.
tile : The combination of the row and column numbers of the index tiles.

The NZ 1:1k Tile Index dataset provides a 1:1,000 scale index for aerial imagery and LiDAR datasets. Along with the 1:5k and 1:10k datasets, this
1:1k tile index is part of a collection of indexes which are referenced to the NZ 1:50k Tile Index dataset.
Like the NZ 1:50k Tile Index, these larger scale indexes support mapping of NZ mainland and coastal areas up to 50m in depth.

The dataset includes the following attributes:

index_tile_id : Unique identifier for the NZ 1:1k tile index table.
sheet_code_id : The corresponding sheet code of the NZ 1:50k Tile Index.
scale : The map scale of the index tiles.
tile : The combination of the row and column numbers of the index tiles.
