Statistical Area 2 2018 (generalised)

  • Added 03 Dec 2017
  • Updated 19 Jun 2019

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.
