This dataset was first added to LINZ Data Service on 08 May 2019.

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.

Coverage areas include Northland, Auckland, Waikato, Hawke’s Bay, Manawatu-Whanganui, Wellington, Tasman, West Coast, Marlborough, Canterbury, Southland and Otago. This dataset will be updated and expanded as new aerial imagery becomes available.

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

This table provides the relationships between building outlines within mainland New Zealand when buildings are split or merged.

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.

Data vintage

This dataset does not include building outline geometry, but provides the linkages between building_id's from different aerial imagery sources in the NZ Building Outlines (All Sources) dataset when building outlines change from single outlines split into multiple outlines, and from multiple outlines merged as single outlines.

This dataset will be updated with changes in building_id relationships as new aerial imagery becomes available.
Please refer to the NZ Building Outlines Data Dictionary for detailed metadata and information about this dataset.

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 areas in Northland, Auckland, Waikato, Hawke’s Bay, Manawatu-Whanganui, Wellington, Tasman, West Coast, Marlborough, Canterbury, Southland and Otago. 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.

This dataset was first added to LINZ Data Service on 20 Dec 2017.

When New Zealand Aerial Mapping (NZAM) went into liquidation in September 2014, LINZ took ownership of their historic archive, and these photos are now available to the public.

This layer has been provided to enable potential users to identify the coverage of aerial photography for Mainland NZ flown by NZAM for private contract work between 1939 and 2008. These surveys compliment the Historic Aerial Photos, Survey Footprints, CROWN (1936-2005) layer which is currently being scanned.

If you are aware of any inaccuracies, please contact LINZ: info@linz.govt.nz or +64 4 4600110. The layer shows the approximate bounding box of each aerial survey undertaken.

How to Access Photos:
The Collection exists as photographic negatives which are not in digital form so the images are not downloadable.

The Collection is managed for LINZ by WSP Opus International. You can order images from the Collection from Opus NZ in a number of formats, including:

  • contact prints
  • enlargements
  • digital files
  • precision scans for photogrammetric production
  • orthophotos

You will need to tell Opus NZ the survey number (the value in the ‘survey’ attribute) covering your area of interest and the name of the survey.

Opus NZ will be able to provide information about the cost of providing images in the various formats. Contact them at: photosales@opus.co.nz or 0800 680 690

There are a small number of surveys that have not been referenced in the LDS layers due to incomplete metadata. Opus NZ will be able to let you know if additional photographs are available in your area of interest.

This dataset was last updated on LINZ Data Service on 13 Aug 2018.

As of May 2019, this pilot dataset has been replaced by the NZ Building Outlines and will no longer be updated. See the NZ Building Outlines Data Dictionary for details on this new buildings dataset.


This pilot dataset consists of building outlines for the majority of New Zealand but does not contain full coverage. It is part of a pilot to understand the benefit of making building outlines data openly available through the LINZ Data Service.

Building outlines are 2D shapes of the edge of a building as visible from aerial imagery, most commonly the roofline edge. It includes spaces such as decks, garages and porches. Each polygon represents a building outline. The outlines were extracted from orthoimagery using an automated process.

Source imagery
Resolution of the imagery used for capture ranges from 50cm pixel resolution (0.5m GSD) to 10cm pixel resolution (0.1m GSD). Please refer to the ‘imagery_source’ attribute for details.

Please note

This is a pilot dataset and is not complete for the whole of New Zealand
While some checks on the data have taken place, there are still errors present
