NZ Addresses is the national authoritative dataset for physical addresses in New Zealand.

This dataset contains the street number, street name and suburb of an address, as well as a unique ID and Territorial Authority.

Refer to the NZ Addresses Data Dictionary for detailed metadata and information about this dataset.

Please note this dataset replaced NZ Street Address in January 2023.

Background

This dataset provides all allocated addresses as advised to Toitū Te Whenua LINZ by Territorial Authorities (TAs). Under the Local Government Act 1974 (section 319) it is the responsibility of the TAs to advise the Surveyor-General at Toitū Te Whenua LINZ of all allocated addresses in their district.

Address data is maintained by Toitū Te Whenua LINZ in the Address Information Management System (AIMS) and Comprehensive Address Data Store (CADS), which are centralised databases for the management of national addresses, including for electoral purposes. This dataset is updated weekly on the LINZ Data Service.

APIs and web services
This dataset is available via ArcGIS Online and ArcGIS REST services, as well as our standard APIs.

This dataset provides an index to the Electronic Navigational Charts (ENC) available through the LINZ Data Service showing extent and ENC attributes.

The ENC index is compiled from the S-57 Object Class “Nautical publication information” which is used to relate additional nautical information or publications to the data. The attributes are populated by Land Information New Zealand’s (LINZ) production database.

S-57 is a standard used to exchange digital hydrographic data between hydrographic offices and to distribute this data to users.
This dataset was compiled for the use in the scale ranges 1:1,000 to 1:1,500,000 and smaller.

THIS DATA DOES NOT REPLACE NAUTICAL CHARTS AND MUST NOT BE USED FOR NAVIGATION.

This data is based on the S-57 data format used in ENCs, published and maintained by the New Zealand Hydrographic Authority at LINZ. Refer to the following link for information about S-57 data: www.linz.govt.nz/hydro/regulation/

This layer identifies critical survey marks which Toitū Te Whenua (Land Information New Zealand) requires to be physically protected.

Thousands of vital survey marks exist in New Zealand. This layer identifies critical survey marks that should not be disturbed or destroyed.
Like utilities such as cables and pipes, survey marks are valuable assets, predominately in the road reserve, with many survey marks set below or at ground level and therefore not highly visible or apparent. They often remain unnoticed until roads or footpaths have been excavated and the survey marks disturbed or destroyed.
Publication of the NZ Protected Survey Marks dataset enables the potential for disturbance or destruction of these valuable survey marks to be assessed, and if needed, the marks protected prior to the commencement of any excavation work.

People involved in construction, from design to the works itself, are responsible for ensuring that survey marks are not disturbed or destroyed. When works have the potential to disturb or destroy existing cadastral and geodetic marks, Toitū Te Whenua needs to be notified so that it can assess whether the marks should be reinstated or replaced. Find out more about looking after the national survey network, and how to contact the Toitū Te Whenua Survey Protection Advisory Service.

Please note there may be other important survey marks not identified on this layer, and that Toitū Te Whenua recommends consultation with a Licensed Cadastral surveyor before any construction or earthworks begin.

If you notice a damaged survey mark, you can report it to Toitū Te Whenua by filling out a form on this website, or by sending feedback via the Geomarks App.

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.

This layer provides all authoritative bearing and distance survey observations which form part of the cadastral survey dataset

Only observations that have been captured in Landonline are available. This includes observations 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.

This dataset only contains right-line survey observations. A small fraction of the total number of survey observations are defined as arcs and are provided via the Survey Arc Chords layer.

This layer provides the extents of influence that the work to integrate survey information has on the surrounding Cadastre.

All cadastral surveys must be integrated into the Cadastre. As part of this process the new information 'upgrades' the existing information. This 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 extend of the change largely depends upon the size of the new survey, the difference in accuracy between new and old data and the number of linkages to other Surveys.

In general, where the underlying surveys are older or in a rural location the greater the extent of the adjustment.

This layer provides survey mark information for marks that are not part of a parcel

A non-boundary mark is any survey mark that is not on a boundary point. The points in this dataset represent physical survey monuments usually placed for cadastral requirements. The data set also includes geodetic marks. Non-boundary marks now enter the Landonline system predominately as part of a cadastral survey dataset (plan) and occasionally via the geodetic processes. For Cadastral marks (i.e.the majority) its name consists of a mark type and number (and is unique to that survey), followed by the ‘plan’ number e.g. IS I DP 3456; IS II DP3456.

Note:
Non-boundary marks used to connect cadastral surveys to the geodetic network are those of 6th order (or better) and this subset is available as the NZ Cadastral Survey Network Marks layer.

This dataset extends the Landonline stored data by including the network accuracy which is based upon its assigned Landonline order - refer LINZS25006 (www.linz.govt.nz/resources/regulatory/standard-tie...).

The accuracy provided relates to the accuracy of coordinates of the mark and has little relevance to the accuracy of the boundary in relation to other boundaries. For example, if the coordinates of the mark were used to locate it, a user would expect to find the existing mark within the accuracy (distance) stated.

This layer provides all marks and associated information that have an order of 6 or better.
Cadastral surveys are required to connect to these marks if they are within a specified distance.

A cadastral survey network mark is a node which is (or was) occupied by a physical survey monument that meets accuracy standards suitable for cadastral requirements. i.e. Cadastral Survey Network Marks have a NZGD2000 horizontal coordinate order of 6 or better. The complete definition for these mark orders is defined by the following Standard.
"www.legislation.govt.nz/regulation/public/2021/009..."

When a new cadastral survey network mark is named as part of a cadastral survey dataset (plan) its name consists of a mark type and number that is unique to that survey, followed by the plan number e.g. IS I DP 3456; IS II DP3456.
