NZ Street Address (Electoral)
**This dataset has been replaced by the** [NZ Street Address](https://data.linz.govt.nz/layer/3353) **and will be deprecated on 31 May 2017**. It is currently being ported from the new database in an effort to minimise disruption for customers. See [Street Address Data Dictionary](https://data.linz.govt.nz/document/1627) for field mappings to the new dataset.
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). ______________________
Generally allocated addresses will be represented by a single point. However there was an historical practice to represent only the principal address allocated by Territorial Authorities, and not include addresses assigned to individual flats. Similarly there was an historical practice to aggregate addresses into ranges, especially where there are many addresses for a single parcel. We are working (where possible) to resolve these historical anomalies and have each allocated address represented where possible. The datasets also includes addresses where the Surveyor General has requested (under the Local Government Act) that a TA allocated an address.
The road name and locality fields attributed to an address are taken from the associated road attributes. These roads are stored as centrelines (see NZ Road Centre Line (Electoral)) and reflect the road names as assigned by the TA responsible. The locality name ensures that if duplicate road names exist in TA that the number/road combination can still be unique by using the locality field.
Wherever address points have been provided in spatial data files by a TA, LINZ will import this data and use the exact location as defined by the TA. Where non spatial data is provided LINZ adds the location of an address point with the mandatory priority to locate that address point within the correct meshblock. The location of the front door of an elector's dwelling within the correct meshblock is a fundamental requirement of the electoral system (Section 72 Electoral Act 1993). Highly desirable priorities for the location of an address point are to have it in the same property and parcel as the dwelling and on the correct side of the physical and legal roads. It is also a desirable priority to have the address point in the same location as the dwelling and/or at the location of the property entrance.
This layer provides all allocated addresses as advised to LINZ by Territorial Authorities.
Following Disclaimers: 1. This data is made available through the LINZ Data Service and is based on information contained with Landonline (New Zealand's Official Title and Cadastral System)
2. The address points represent known addresses for electoral enrolment purposes. They do not necessarily represent occupied properties

A formal process to record and continually maintain address information in a national dataset was introduced in 1979 when the functions performed by the Electoral Office were split amongst various government agencies based on their areas of specialist expertise. Lands & Survey was assigned the responsibility of creating and maintaining an Index to Places and Streets for NZ, and also to provide mapping to support electoral enrolment. A later requirement for common enrolment resulted in the transfer of meshblock mapping from Statistics New Zealand to Lands & Survey so that the accuracy of meshblock mapping could be improved and so that meshblocks could be aligned to cadastrally defined property boundaries wherever practical.
To achieve these responsibilities, the department created a textual database of streets (including addressing) and places, and compiled a set of electoral record maps on which the location of road names, street addresses and meshblocks were recorded. The data was collected as quickly as possible from a variety of sources. Most of the Address numbering came from Territorial Authorities via their rating records. This was supplemented with additional information sourced from valuation rolls, street maps, topographic maps, and farm property maps. The information collected was later validated over time as part of the electoral enrolment process and consequential communication with the Territorial Authorities and other electoral agencies.
The Digital Cadastral Database (DCDB) initially focused on Cadastral information however, once the nationwide capture of DCDB neared completion a decision was made to include all remaining electoral data from the electoral record maps, i.e. meshblocks, road names, and street addresses. In most cases the road and address information had already been captured (primarily due to their value as a search key).
Within Landonline only road names and addresses that are considered to be official were intended to be recorded, however sometimes cases may arise where information for electoral enrolment purposes needs to be temporarily recorded until discrepancies in official road name and street address records can be resolved. These flags are rarely used and are not included in this derived dataset.
Individual address points are usually created to represent separate dwellings, however for display purposes in Landonline, some addresses are aggregated into ranges. This is especially common for complex sites such as retirement villages and larger unit title developments.
The dataset source was changed to the AIMS database system from 20 Nov 2016.
