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 dataset provides current outlines of buildings within mainland New Zealand captured from the latest aerial imagery.

A building outline is a 2D representation of the roof outline of a building which has been classified from LINZ aerial imagery using a combination of automated and manual processes to extract and refine a building roof outline.

Building outlines observed in aerial imagery larger than or equal to 10 square meters are captured in this dataset, and may include structures such as garages and large sheds.

Data vintage

This dataset shows the most recent set of building outlines extracted from the LINZ aerial imagery available on the LINZ Data Service.

Current coverage includes nearly all regions of New Zealand, except parts of rural Auckland, remote parts of Bay of Plenty, Tasman and the Southern Alps, as well as Fiordland, Stewart Island and the Chatham Islands. This dataset will be updated and expanded as new aerial imagery becomes available.

Since aerial imagery is flown only every few years in each region of the country, building outlines only reflect those buildings observed at the date of this aerial imagery capture, and may not reflect buildings constructed after this time period.

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

Related building outlines data

NZ Building Outlines (All Sources) - contains all combinations of building outlines from multiple years of imagery that have existed since the beginning of this dataset, and the dates when each building outline existed in the associated aerial imagery.

NZ Building Outlines Lifecycle - is related to the dataset above and stores the relationship between building outlines when one building is split into two or more building outlines, or when multiple building outlines are merged into a single outline.

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.

This dataset was first added to LINZ Data Service on 06 Aug 2019.

This dataset provides river name lines for mainland New Zealand. It is part of a pilot to understand the benefit of combining river names and location, and making these openly available through the LINZ Data Service.

Unnamed rivers are also included in this dataset.

How this data can be used

Together with the NZ River Name Polygons (Pilot) dataset, these are the first openly available datasets with NZ river names attributed to geometry features (lines and polygons). This data can be used for searching for a named river and zooming to its extents, extracting geometries of a named river, creating digital cartographic products displaying river names, and analysing other features against named rivers (e.g. identifying buildings or properties within a specified distance of a particular river).

Data vintage

The river names and extents in this dataset are based on the cartographic text shown on NZ Topo50 maps as of December 2018, and are an approximation and should not be taken as official. Further details are included in the 'Naming Extents Methodology' section in the 'Lineage' of this metadata.
Please refer to the NZ River Name Lines and Polygons (Pilot) Data Dictionary for detailed metadata and information about this dataset.

Related data

NZ River Name Polygons (Pilot) - contains larger rivers captured as polygon features instead of lines.

We recommend using the two river name datasets with the following NZ Topo50 layers for connectivity and visualisation of inland hydrographic features.

The NZ River Name Lines and Polygons (Pilot) Data Dictionary provides details on how to download the matching time period snapshots of this data.

Please note

  • Official geographic names as listed in the New Zealand Gazetteer of place names must be used in all official documents as per the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008.

  • This pilot dataset is unlikely to be updated, however feedback will be used for future enhancements to LINZ river datasets.

This dataset provides building outlines within mainland New Zealand extracted from multiple years of aerial imagery, allowing you to see change over time, or restrict the dataset to building outlines that match a specific aerial imagery source.

A building outline is a 2D representation of the roof outline of a building which has been classified from LINZ aerial imagery using a combination of automated and manual processes to extract and refine a building roof outline.

Building roof outlines observed in aerial imagery larger than or equal to 10 square meters are captured in this dataset, and may include structures such as garages and large sheds.

Data vintage

This dataset contains all building outlines which have been extracted from multiple years of aerial imagery available in each region of the country, including the most recent imagery. This dataset includes the dates for which each building existed in the aerial imagery.

This dataset was first added to LINZ Data Service on 14 Jun 2021.

This dataset provides boundaries of facilities, currently hospitals and schools, within mainland New Zealand originally sourced in early 2021 from a combination of NationalMap and authoritative sources, including NZ Ministry of Education and NZ Ministry of Health.

A facility represents a particular activity such as a hospital or school. A facility boundary represents the extent of the land which appears to be used by a facility. A facility boundary can be different to corresponding cadastral parcel polygons because a facility can span across multiple parcels or be located in only part of a parcel. For example, a parcel owned by the crown can include multiple schools and other facilities such as parks and reserves.

Facility boundaries in this dataset were used to apply hospital and school building names to the NZ Building Outlines dataset published on the LINZ Data Service.

A more detailed description of NZ Facilities can be found in the NZ Facilities Data Dictionary. This Data Dictionary also includes information on how NZ Facilities was used to support the attribution of NZ Building Outlines.

NZ Facilities contains data sourced from NationalMap, Ministry of Education and Ministry of Health licensed for reuse under CC BY 4.0.
