This dataset is the definitive version of statistical area 2 (SA2) boundaries clipped to the coastline and concorded to higher geographies as at 1 January 2018 as defined by Stats NZ.
This statistical area 2 higher geographies file is a correspondence, or concordance, which relates SA2s to larger geographic areas or 'higher geographies'. The higher geographies contained in this concordance are: territorial authority (TA) and regional council (REGC).
Statistical area 2 (SA2) is a new output geography that provides higher aggregations of population data than can be provided at the statistical area 1 (SA1) level. The SA2 geography aims to reflect communities that interact together socially and economically. In populated areas, SA2s generally contain similar sized populations.
This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.
For more information on individual higher geographies, refer to their metadata.
