Roads and Addresses Data

As of June 2017, this dataset has been replaced by the NZ Street Address and will no longer be updated. See Street Address Data Dictionary 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.

As of June 2017, this dataset has been replaced by NZ Roads Subsections (Addressing) and will no longer be updated. See NZ Roads Data Dictionary for field mappings to the new dataset.

This layer provides a feature representing Electoral road subsection (e.g. a city block) to which associated data such electoral addresses can be attached.

In Landonline a road name is commonly assigned to multiple stretches of roading such as between intersections with other roads. For this layer each of these individual road sections have their own geometry (as opposed to the Road Centre Line Layer where they have been aggregated).

A road may also have more than one road name, some road centreline geometries will duplicate other roads subsections even though there is in reality only one road formation. In addition, a road name is also commonly duplicated across the country e.g. "Queen Street", "High street" etc

The source Landonline data exists in order to provide 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.

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

As a general rule those that are not within a Road Parcels Layer should be treated as being of highly variable accuracy. They do however meet the purposes for which they have been captured, and can provide a valuable resource for other purposes provided that the user(s) understand their origin and consequential limitations.

Warning: The purpose of the location field is to enable differentiation between roads of the same name in the dataset. It should not be considered official nor part of a valid postal address. It can however be used as an indicative guide to location within a Territorial Authority, or in the case of regional road networks, as an indicative guide to location within New Zealand.

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 road centreline in this layer will typically consist of several road centreline geometries from Landonline that have been associated to the same road name.
In Landonline a road name is commonly assigned to multiple stretches of roading such as between intersections with other roads. A road name is also commonly duplicated across the country e.g. "Queen Street", "High street" etc.

For this layer (as opposed to the Road Subsections Layer. Individual road sections have been aggregated to a single road centreline geometry for each locality. Thus, for example, State Highway 1 has individual sections for differing towns and whenever it crosses a Territorial Authority boundary.

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.

In June 2014, LINZ moved the information from the Authoritative Streets and Places database (ASP) into Landonline and the ASP database is no longer maintained.

This table allows the application to check for invalid combinations of TLA, Electorate, Maori & 260 sheet references at the time of data entry. This table is recreated every time a new set of electoral boundaries takes effect, and is subsequently updated if new valid combinations are discovered.

This table is part of the Authoritative Streets and Places (ASP) Database. For more information about the database including the data model see here.

Notes:

• This table contains a static unique identifier 'id' column that is not part of the original published ASP database. This column has been added to support incremental changesets on LDS. There is a direct relationship between this column and the original primary key on the 'combination' column.

This table identifies other names for a street or place record by linking to the SUFI of the other name. This allows multiple associations if applicable. Only one record is stored for each name/other_name combination, i.e. there is no reverse entry for any two SUFI’s.

Notes:

• The Alias field was added during the conversion and all records were initially set to N (No). This field will be set if relevant when editing existing records or adding new records. The values for other records will be set when time permits.
