Roads and Addresses Data

Please read:This dataset 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. See below for details.

This dataset contains the core components of an address to support simple searching or use of this data to provide context. 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.

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

For a comprehensive group of address tables see AIMS: Street Address.

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).

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 refer to the NZ Roads Data Dictionary for detailed metadata and information about this layer.

Please read: This dataset 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 dataset (as opposed to the NZ Roads Subsections (Addressing) dataset, 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 dataset 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.

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.

This dataset contains the core attributes of a road to support simple searching or provide a road name context for cadastral data views. Please refer to the NZ Roads Data Dictionary for detailed metadata and information about this dataset.

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 refer to the NZ Roads 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 layer contains information 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.

For a simplified version of the data contained within these tables see NZ Street Address.

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

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:

• Official locality names from NZ Localities - NZGB Compliant Names

• Territorial Authority association

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.

Feedback
We welcome your feedback on NZ Addresses (Pilot). The questions below could help guide feedback:
1. How useful is NZ Addresses (Pilot) to your application?
2. Have you identified any aspects of NZ Addresses (Pilot) that could be improved?
3. Have you encountered any addresses that you feel should not have been included as a missing address?
4. Any other feedback?

Please direct feedback to: addresses@linz.govt.nz with the subject line ‘NZ Addresses (Pilot) Feedback’.

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.
