This layer only contains those place names that have a polygon geometry captured for them.
For the complete list of place names see NZ Place Names.

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 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.

Coordinates computed from surveys undertaken after the 14 February 2016 Canterbury earthquake. These should be consistent with any observations made after this earthquake (neglecting any localised deformation such as that due to liquefaction).

For further information about this dataset, see the Canterbury earthquake information.

These coordinates are only provisional. Analysis is ongoing as further data is collected. Coordinates were calculated using SNAP v2.5.33. Stations were constrained using coordinates of distant PositioNZ continuous GNSS stations that were unaffected by the earthquake.

The standard deviations of coordinates are 0.01m horizontally and 0.02m vertically, relative to the PositioNZ network.

Coordinate changes due to the earthquake have been calculated by comparing pre and post-earthquake coordinates. Pre-earthquake coordinates were calculated relative to public and private continuous GNSS stations. These continuous GNSS stations had data processed for several days early in 2016 (before the earthquake). Other pre-earthquake geodetic data was then readjusted with the continuous GNSS data. Note that this means these coordinate changes may differ slightly from those that would be calculated by comparing the post-earthquake coordinates with those currently in the Geodetic Database.

These coordinates are suitable for use in surveys and other geospatial activities in Canterbury and Christchurch.

The LTN37-NZGD2000 grid enables the conversion of normal-orthometric heights from the Lyttelton 1937 local vertical datum directly to New Zealand Geodetic Datum 2000 (NZGD2000) ellipsoidal heights.

LTN37-NZGD2000 is published on a one arc-minute grid (approximately 1.8 kilometres) extending over the benchmarks that nominally define the extent of the Lyttelton 1937 vertical datum (168.53° E to 174.2° E, 41.3° S to 45.1° S).

The conversion value is represented by the attribute “delta”, in metres.

This grid is a combination of New Zealand Quasigeoid 2016 NZGeoid2016 and the LTN37-NZVD2016 height conversion grid. Where NZGeoid2016 is the reference surface for the New Zealand Vertical Datum 2016 (NZVD2016), while the LTN37-NZVD2016 grid models the difference between the Lyttelton 1937 vertical datum and NZVD2016 using the LINZ GPS-levelling marks.

More information on converting heights between vertical datums can be found on the LINZ website.

New Zealand Quasigeoid 2016 Raster, provides users with a one arc-minute gridded (approximately 1.8 kilometres) raster image of the New Zealand Quasigeoid 2016 (NZGeoid2016).

The relationship between the GRS80 ellipsoid and the New Zealand Vertical Datum 2016 (NZVD2016) is modelled by [NZGeoid2016] and is represented by the attribute “N”, in metres.(data.linz.govt.nz/layer/3418).
NZVD2016 is formally defined in the LINZ standard LINZS25009.

Users may also be interested in transforming heights to any of the 13 historic local vertical datums used in New Zealand using the appropriate datum relationship grid displayed in the NZ Height Conversion Index.

More information on these transformations is available on the LINZ website.

The relationship between the GRS80 ellipsoid and the New Zealand Vertical Datum 2016 (NZVD2016) is modelled by the New Zealand Quasigeoid 2016 (NZGeoid2016). The relationship value is represented by the attribute “N”, in metres.

This relationship and NZVD2016 is formally defined in the LINZ standard LINZS25009.

NZGeoid2016 can be used to convert New Zealand Geodetic Datum 2000 (NZGD2000) ellipsoidal heights to NZVD2016 normal-orthometric heights.

The conversion value is represented by the attribute “N”, in metres.

NZGeoid2016 is published on a one arc-minute grid (approximately 1.8 kilometres) over the New Zealand continental shelf (160° E to 170° W, 25° S to 60° S).

NZGeoid2016 was calculated by enhancing the EIGEN-6C4 global gravity model with, terrestrial, ship-track, satellite and airborne gravity data. GPS-levelling observations were not used to compute NZGeoid2016.

Users may also be interested in transforming heights to any of the 13 historic local vertical datums used in New Zealand using the appropriate datum relationship grid displayed in the NZ Height Conversion Index.

More information on these transformations is available on the LINZ website.

The AUK46-NZVD2016 grid enables the conversion of normal-orthometric heights from the Auckland 1946 local vertical datum to the New Zealand Vertical Datum 2016 (NZVD2016).

The conversion value is represented by the attribute “O”, in metres.

This conversion and NZVD2016 are formally defined in the LINZ standard LINZS25009.

AUK46-NZVD2016 is published on a two arc-minute grid (approximately 3.6 kilometres) extending over the benchmarks that nominally define the extent of the Auckland 1946 vertical datum (174.0° E to 176.2° E, 36.1° S to 38.0° S).

The height conversion grid models the difference between the Auckland 1946 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy of AUK46-NZVD2016 is better than 2 centimetres (95% Confidence interval).
