This pilot dataset provides more comprehensive national address data for New Zealand, incorporating previously missing addresses to our official address data.

NZ Addresses (Pilot) comprises both AIMS addresses and allocated addresses identified as missing from AIMS gathered from Territorial Authorities.

To improve ease of use, this dataset also includes:

Please note: we are still working through a process of identifying missing addresses. NZ Addresses (Pilot) will continue to be populated with missing addresses as they are verified.

AIMS address set and the simplified version NZ Street Address will continue to be updated by LINZ as normal as advice is received from Territorial Authorities.

In June 2022, NZ Addresses will become the national, authoritative dataset for physical addresses, replacing NZ Street Address.

Update August 2022 - Customer feedback identified an issue which is generating some duplicate addresses in NZ Addresses. We hope to resolve this as soon as possible and publish NZ Addresses as the national, authoritative dataset for physical addresses.


About the validation process
The Toitū Te Whenua LINZ Addressing Team developed routines and procedures to validate address sets sourced from Territorial Authorities against the AIMS address set.

A pilot project ran for six months, until December 2021, to gather feedback. Thank you for your valuable responses which have helped improve the data. Further validation of NZ Addresses (Pilot) will continue for six months until June 2022.

NZ Addresses (Pilot) remains for test purposes only at this stage. The pilot dataset is not intended to be used in place of the AIMS suite of published addresses, including NZ Street Address.

In June 2022, NZ Addresses will become the national, authoritative dataset for physical addresses, replacing NZ Street Address. We welcome any additional feedback as we work towards this goal.

Data fields
Please refer to the Street Address Data Dictionary for detailed metadata and information about the AIMS fields in this dataset.

NOTE: there are a few differences between the existing AIMS dataset and this dataset.

  • New addresses identified are named ‘CADS’ (Comprehensive Addresses Data Store) addresses.

  • Some new fields include source_dataset (the source of the record, e.g. CADS or AIMS), and address_lifecycle.

  • Field address_id is the unique identifier for an address in either AIMS or CADS addresses.

  • Field change_id is the unique identifier for the address version in either AIMS or CADS addresses.

  • Field address_class is same as address_type and includes throughfare and water.

  • Field road_section_id is not included in this dataset.

The NZ Elevation Survey Index dataset provides an index to all LiDAR derived elevation datasets found on the LINZ Data Service. Each record in the dataset provides both a geometry of the extent of the elevation survey, as well as useful metadata attributes. The extents are derived from the maximum extent of DEM and DSM coverage and consist of full NZTopo50 1k tiles, even where a tile is only partially covered with data. These extents only provide a rough indication of corresponding point cloud coverage which can be quite different for some elevation surveys.

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

The elevation data referenced by this dataset is available on the LINZ Data Service.

This dataset was last updated on LINZ Data Service on 02 Dec 2022.

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 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/about-linz/news-publications-and-...).

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.linz.govt.nz/survey-titles/cadastral-surveying..."

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.

This dataset was last updated on LINZ Data Service on 02 Dec 2022.

This layer provides the latest bearing (direction) and/or distance for cadastral boundaries.

When a cadastral survey is undertaken the relationship between boundary and non-boundary marks is ascertained or measured.
• This commonly is in the form or a vector (bearing and distance), but occasionally just one component.
• Some relationships are defined as arcs. In this data layer, the arc length is recorded in the distance field and a separate record holds the chord.

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.
