Statistical Area Level 1 (SA1)

Statistical Areas Level 1 (SA1s) are designed to maximise the geographic detail available for Census of Population and Housing data while maintaining confidentiality.

SA1s are built from whole Mesh Blocks and have a population between 200 and 800 people. In remote and regional areas they generally have smaller populations than those in urban areas. SA1s are designed to represent Aboriginal and Torres Strait Islander communities as accurately as possible, particularly in remote areas.

Using SA1s with Census data

Use SA1s to see how Census characteristics vary at a neighbourhood scale within larger areas such as Suburbs or Local Government Areas.

This dataset is the definitive version of the annually released statistical area 1 (SA1) boundaries as at 1 January 2025, as defined by Stats NZ. This version contains 33,164 SA1s (33,148 digitised and 16 with empty or null geometries (non-digitised)).

SA1 is an output geography that allows the release of more low-level data than is available at the meshblock level. Built by joining meshblocks, SA1s have an ideal size range of 100–200 residents, and a maximum population of about 500. This is to minimise suppression of population data in multivariate statistics tables.

The SA1 should:

form a contiguous cluster of one or more meshblocks,

be either urban, rural, or water in character,

be small enough to:

• allow flexibility for aggregation to other statistical geographies,

• allow users to aggregate areas into their own defined communities of interest,

form a nested hierarchy with statistical output geographies and administrative boundaries. It must:

• be built from meshblocks,

• either define or aggregate to define SA2s, urban rural areas, territorial authorities, and regional councils.

SA1s generally have a population of 100–200 residents, with some exceptions:

• SA1s with nil or nominal resident populations are created to represent remote mainland areas, unpopulated islands, inland water, inlets, or oceanic areas.

• Some SA1s in remote rural areas and urban industrial or business areas have fewer than 100 residents.

• Some SA1s that contain apartment blocks, retirement villages, and large non-residential facilities (prisons, boarding schools, etc.) have more than 500 residents.

SA1 numbering

SA1s are not named. SA1 codes have seven digits starting with a 7 and are numbered approximately north to south. Non-digitised codes start with 79.

As new SA1s are created, they are given the next available numeric code. If the composition of an SA1 changes through splitting or amalgamating different meshblocks, the SA1 is given a new code. The previous code no longer exists within that version and future versions of the SA1 classification.

Digitised and non-digitised SA1s

The digital geographic boundaries are defined and maintained by Stats NZ.

Aggregated from meshblocks, SA1s cover the land area of New Zealand, the water area to the 12-mile limit, the Chatham Islands, Kermadec Islands, sub-Antarctic islands, off-shore oil rigs, and Ross Dependency. The following 16 SA1s are held in non-digitised form.

7999901; New Zealand Economic Zone, 7999902; Oceanic Kermadec Islands,7999903; Kermadec Islands, 7999904; Oceanic Oil Rig Taranaki,7999905; Oceanic Campbell Island, 7999906; Campbell Island, 7999907; Oceanic Oil Rig Southland, 7999908; Oceanic Auckland Islands, 7999909; Auckland Islands, 7999910; Oceanic Bounty Islands, 7999911; Bounty Islands, 7999912; Oceanic Snares Islands, 7999913; Snares Islands, 7999914; Oceanic Antipodes Islands, 7999915; Antipodes Islands, 7999916; Ross Dependency.

This dataset is the definitive set of annually released statistical area 1 (SA1) boundaries for 2022 as defined by Stats NZ (the custodian). This version contains 29,913 SA1 features.

SA1s were introduced as part of the Statistical Standard for Geographic Areas 2018 (SSGA18) which replaced the New Zealand Standard Areas Classification (NZSAC92). SA1 is an output geography that allows the release of more detailed information about population characteristics than is available at the meshblock level.

Built by joining meshblocks, SA1s have an ideal size range of 100–200 residents, and a maximum population of about 500. This is to minimise suppression of population data in multivariate statistics tables. SA1s either define or aggregate to define SA2s, urban rural areas, territorial authorities, and regional councils. Some SA1s that contain apartment blocks, retirement villages, and large non-residential facilities have more than 500 residents.

This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.

Digital boundary data became freely available on 1 July 2007.

The SA1 classification can also be downloaded from the Stats NZ classification and concordance tool Ariā.

Statistical Area 1 2023 update

SA1 2023 is the first major update of the geography since it was first created in 2018. The update is to ensure SA1s are relevant and meet criteria before each five-yearly population and dwelling census. SA1 2023 contains 3,251 new SA1s. Updates were made to reflect real world changes including new subdivisions and motorways, improve the delineation of urban rural and other statistical areas and to ensure they meet population criteria by reducing the number of SA1s with small or large populations.

The VG data is from a single point in time and contains information for properties as of 2014. (eg. including extensions/renovations or where subdivision has been undertaken, which would include any increases in floor area or decreases in land area that occurred as a result of these). The VG oversee valuations for State Government property transactions and the making and return of council rating valuations. The primary data items used include Land Use, Property Area, Equivalent Main Area and Year built. "Equivalent main area" is the total area under the main roof excluding area of eg. carports, garages, verandahs etc. rather than the building footprint. Only landuse codes with a classification of "Private" were included in the analysis. State Office Land Use Classification 2007 was used to analyse Valuer General data. Only records classified as Single Unit Houses (land use code 1100-1119) were included in the analysis (80% of VG records), but this will include multistory houses. Because the area calculation for multistory houses could exceed the size of the land parcel, a "MeanAreaRatio_adj field has been included - Where the Pre1980_MeanAreaRatio for a property is greater than 100.0, then this has been adjusted down to 100.0 The analysis was restricted to Private Single Unit Houses (excluding multiple unit dwellings and commercial buildings) in an effort to enable the data to be used to understand residential backyard sizes and how these have changed over time. Note that although the figure heading notes a year range of 1990-2014 the original output dataset for Statistical Area Level 1 s(SA1) included records with a null year field (326 records) as well as records dating back to 1838.

Indigenous Locations (ILOC)

Indigenous Locations (ILOCs) represent small Aboriginal and Torres Strait Islander communities (urban and rural) that are near each other or that share language, traditional borders, or Native Title. Indigenous Locations (ILOCs) are geographic areas built from whole Statistical Areas Level 1 (SA1s).

ILOCs usually have a minimum population of about 90 usual residents. In some cases, they may have a smaller Aboriginal and Torres Strait Islander population to meet statistical requirements or to better represent the local community. ILOCs combine to form Indigenous Areas (IAREs).

Using ILOCs with Census data

Use ILOCs if you require very specific information about an area. Due to their small population size, there are limitations to the quality of data at this geography level.

This is to minimise suppression of population data in multivariate statistics tables.The official dataset can be found on https://datafinder.stats.govt.nz.This layer contains the following attributes (see data tab):Statistical Area 1 codeLand - Water codeLand - Water descriptionTotal area in square kilometersTotal land area in square kilometers.The layer is further generalised by Eagle Technology for improved performance on the web, therefore it doesn't fully represent the official boundaries.This layer is offered by Eagle Technology (Official Esri Distributor). Eagle Technology offers services that can be used in the ArcGIS platform.
