This dataset was first added to LINZ Data Service on 15 Aug 2018.

The NZ Imagery Surveys dataset contains a comprehensive index of 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 Imagery Surveys Data Dictionary for detailed metadata and information about this layer.

Please read: This layer provides linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist.

A linear geometry in this layer will consist of the individual road section geometries (as opposed to the NZ Roads (Addressing) layer where these have been aggregated). This layer has been simplified from LINZ’s NZ Roads database, a centralised database for the management of national road data. The comprehensive set of NZ Roads tables is also available.

These road centrelines do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal.

Some road sections have multiple names; in these cases the non-primary road names are held in additional columns against each road section.

This layer contains the core attributes of a road section to support simple searching with locality and territorial authority or provide a road name context for cadastral data views. This layer is a replacement for the NZ Road Centre Line Subsections (Electoral) layer.

The Electoral road and address datasets will be available until May 2017 to allow users further time to transition.

Please read: This layer provides linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist.

For this layer (as opposed to the NZ Roads Subsections (Addressing) layer, individual road section geometries have been aggregated to a single road centreline geometry where those subsections share the same name, and are generally contiguous. Because some roads have multiple names for part of their lengths, some road centreline geometries will duplicate parts of other roads even though there is in reality only one road formation. This layer has been simplified from LINZ’s NZ Roads dataset, a centralised database for the management of national road data. The comprehensive set of NZ Roads tables is also available.

Please read: This is the table for Road Section Geometry, which is part of the set of NZ Roads tables. The Road Section Geometry table stores the linear geometry for the associated road section, or part of the associated road section.

The NZ Roads dataset includes eight data tables and eleven lookup tables. The dataset has been sourced from LINZ’s NZ Roads database, a database for the management of national roads, including those managed for addressing purposes. This set of normalised tables replaces the Landonline: Road Centre Line layer and the Landonline: Road Name and Landonline: Road Name Association tables currently published on LDS.

These centrelines are required to indicate the presence of an authoritative road name. Named centrelines are not intended to represent the exact location of a road formation. Named centrelines do not indicate the presence of legal access.

For a simplified version of the data contained within these tables see NZ Roads (Addressing), which aggregates geometries based on road name, and NZ Roads Subsections (Addressing), which holds the individual geometries.

Please read:This layer provides all allocated addresses as advised to LINZ by Territorial Authorities (TAs). Under the Local Government Act 1974 (section 319) it is the responsibility of the TAs to advise LINZ (the Surveyor General) of all allocated addresses in their district.


Local Government Act 1974
319B Allocation of property numbers
(1) For electoral, postal, and other purposes the council may allocate a number to any area of land or building or part of a building within its district and may change the number allocated to any such area of land or building.
(2) The council shall comply with any request from a Chief Surveyor to allocate a number to or change the number of any area of land or building or part of a building in its district.
(3) The principal administrative officer shall advise the Chief Surveyor of the land district in which the land or building is situated of the numbers allocated under subsection (1) or subsection (2).


This dataset contains the core components of an address to support simple searching or use of this layer to provide context and is a replacement for the NZ Street Address (Electoral) dataset. This dataset has been sourced from LINZ’s Address Information Management System (AIMS), a centralised database for the management of national addresses, including for electoral purposes.

The existing address and road datasets will be available for 6 months after AIMS go-live to allow users further time to transition.This version will be replacing NZ Street Address (Electoral) dataset.

Please refer to the Street Address Data Dictionary for detailed metadata and information about this layer.

Please read: The AIMS: Address Position table is part of the set of comprehensive AIMS Address tables.

The Address Position table contains the point location of an address. An address can have multiple point positions. The Addresspositiontype describes the position E.g. centroid, set back from road. In the first instance the Landonline address position will be used the positioning of this is 'unknown'. Additional Address Position data may be captured over time.

The comprehensive address dataset includes eight data tables and nine lookup tables. The dataset has been sourced from LINZ’s Address Information Management System (AIMS), a centralised database for the management of national addresses, including for electoral purposes. This set of normalised tables replaces the single Landonline: Street Address layer currently published on LDS.

This 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

This layer provides the extents of the data incorporated into an adjustment which has been completed as a Wide Area Cadastral Adjustment (WACA). These adjustments are undertaken in areas where there is already substantial survey-accurate data, but there are some inconsistencies in the data resulting from small changes to geodetic control coordinates and/or the progressive submission of additional Cadastral Survey Datasets (CSDs). The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be no more than 10cm, as the WACAs target areas where coordinates already have fairly high spatial accuracy.

This layer provides the extents of the data incorporated into an adjustment which has been completed as part of the Spatial Parcel Improvement (SPI) project. The SPI project aims to improve the accuracy of digital cadastral data in areas (primarily rural) where survey-accurate data does not currently exist. The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be at least several metres, as the SPI project targets areas where significant movements are expected.

This layer provides all authoritative arc survey observations and is targeted at cadastral surveyors.

Only observations that have been captured in Landonline are available. This includes vectors that were re-captured in the Survey Capture Areas from survey plans lodged prior to Landonline and all survey observations since.

Individual cadastral surveys will commonly re-measure or re-use cadastral lines. Often they will be the same, however as the accuracy capability has increased over time, differences between 'old' and 'new' observations are more likely. Thus all survey observations include the reference to the Survey Plan.
