This dataset was last updated on Stats NZ Geographic Data Service on 13 Jan 2021.

This dataset is the definitive set of annually released statistical area 1 (SA1) boundaries concorded to higher geographies for 2021 as defined by Stats NZ. This version contains 29,910 SA1s including 16 with empty or null geometries (non-digitised SA1s).

This SA1 higher geographies 2021 file is a correspondence, or concordance, which relates SA1s to larger geographic areas or 'higher geographies'. The higher geographies contained in this concordance are: regional council (REGC2021), statistical area 2 (SA22021), territorial authority (TA2021), urban rural (UR2021), urban rural indicator (IUR2021), and urban accessibility indicator (IUA2021). The following geographies were introduced in 2018: statistical area 1 (SA1), statistical area 2 (SA2), urban rural (UR), and urban rural indicator (IUR) as part of the Statistical Standard for Geographic Areas 2018 (SSGA18) which replaced the 1992 New Zealand Standard Areas Classification (NZSAC92). The urban accessibility indicator (IUA), which measures the degree of urban influence New Zealand's urban areas have on surrounding rural areas, was first added to this correspondence in 2021.

Higher geography names are provided with and without tohutō/macrons, as applicable. Column names for those without macrons are suffixed ‘ascii’. For further information on individual higher geographies, refer to each geography’s metadata.

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.
