This dataset is the definitive set of meshblock boundaries for 2013 as defined by Statistics New Zealand.
Statistics New Zealand maintains an annual meshblock pattern for the collection and production of statistical data, allowing data to be compared over time. A meshblock is the smallest geographic unit for which statistical data is collected and processed by Statistics New Zealand. A meshblock is defined by a geographic area, which can vary in size from part of a city block to a large area of rural land. Each meshblock abuts against another to form a network covering all of New Zealand, including coasts and inlets and extending out to the 200 mile economic zone. Meshblocks are added together to build up larger geographic areas such as area units and urban areas. They are also used to define electoral districts, territorial authorities and regional councils.
Meshblocks are allocated a unique seven-digit number. The first 5 digits are unique, and refer to the original 1976 meshblock code. The two end numbers refer to sequential meshblock splits to the original meshblock. When a meshblock is split the final two digits of the original meshblock number are changed. Exceptions to this rule are a small number of meshblocks where no more numbers in the sequence are available. There are therefore some meshblocks in Auckland and Tauranga City starting with 32xxxxx. Statistics New Zealand maintains a concordance file to ensure that boundaries relating to earlier meshblock patterns can also be produced.
There are two ways of amending meshblock boundaries.
- Splitting is the subdivision of a meshblock into two or more meshblocks.
- Nudging is the shifting of a boundary to a more appropriate position.

This dataset is the definitive set of statistical area 2 (SA2) boundaries at 1 January 2018 as defined by Stats NZ. SA2 is a new output geography that provides higher aggregations of population data than can be provided at the statistical area 1 (SA1) level. SA2s are defined at SA1 and meshblock levels. Digital boundary data became freely available on 1 July 2007. This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes. For further information see ANZLIC Metadata 2018 Statistical Area 2 attachment below or link to the StatsNZ Classification System Aria.

Please note that a review of SA2 names was undertaken in early 2018. The review addressed issues with inconsistent naming and applied corrections, resulting in an update to this dataset applied in May 2018. All SA2 codes are unchanged.

This dataset is the definitive set of statistical area 1 (SA1) boundaries at 1 January 2018 as defined by Stats NZ. SA1 is a new output geography that allows for the release of more detailed information about population characteristics than is available at the meshblock level. SA1s are defined at meshblock level.

In New Zealand, internal migration is typically the most difficult component of net migration’s contribution to subnational population change to measure. Internal migrants are not required to register their moves with any agency. The five-yearly census of population and dwellings has included a question on “usual residence five years ago” since 1971, which has been the authoritative data source for measuring internal migration. However, the infrequency of the collection (every five years), and the ‘snapshot’ nature of a transition-based measure are significant limitations. Other measures of annual subnational population change, such as the Treasury’s Insights tool, provide estimates of internal migration flows between TAs by using linked administrative data. Their approach identifies a set of decision rules for assigning location to individuals, based on a quality assessment of a wide range of address sources in the IDI (Where we come from, where we go). The TA location transitions provide the basis for deriving statistics of annual internal migration as demonstrated by the Insights tool. The data published with this report is the first series we’ve created by estimating all internal migration flows using a movement-based approach. From individuals’ unique address notification histories in key data sources, the paired origin and destination locations defined individuals’ movements. Traditionally, we combined change of address data from a range of administrative sources with other information on international migration to produce estimates of net migration for broad subnational areas. Now, we can derive direct estimates of movements from address histories from the anonymised unit record information of address notifications in the IDI. This gives a better understanding of people’s movements within New Zealand. Internal migration information is of great interest to local and central government, businesses, and communities. Churn and turnover of populations at local area level is one of the contributors of subnational population change, in both size and characteristics.

This dataset is the major released version of the annually released ward boundaries at 1 January 2019, clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and does not fully represent the official full extent boundaries. Wards are defined under the Local Electoral Act 2001 and result from dividing a territorial authority for electoral purposes. Wards are defined at meshblock level.

Digital boundary data became freely available on 1 July 2007. This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.

This dataset is the definitive set of ward boundaries 1 January 2019 as defined by the territorial authorities and/or Local Government Commission, and maintained by Stats NZ. Wards are defined under the Local Electoral Act 2001 and result from dividing a territorial authority for electoral purposes. Wards are defined at meshblock level.

This dataset is the definitive set of the annually released urban rural boundaries at 1 January 2019, clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and may not fully represent the official full extent boundaries. Urban rural is an output geography that classifies New Zealand into areas that share common urban or rural characteristics. Urban areas are built from the Statistical Area 2 geography, while rural and water areas are built from the Statistical Area 1 geography. Urban areas are statistically defined areas with no administrative or legal basis. The urban rural indicator is an attribute of this classification and provides additional information about a location's urban or rural nature.
