This dataset is the definitive set of meshblock boundaries concorded to higher geographies for 2021. This version contains 53,598 meshblocks, including 16 with empty or null geometries (non-digitised meshblocks). This Meshblock Higher Geographies 2021 file is a correspondence, or concordance, which relates meshblocks to larger geographic areas or 'higher geographies'. The higher geographies contained in this concordance are: community board (CB2021), constituency (CON2021), Māori constituency (MCON2021), Māoriward (MWARD2021), regional council (REGC2021), statistical area 1 (SA12021), statistical area 2 (SA22021), territorial authority local board (TALB2021), territorial authority (TA2021), subdivision (TASUB2021), urban accessibility indicator (IUA2021), urban rural (UR2021), urban rural indicator (IUR2021), and ward (WARD2021).The following geographies were first 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 geography urban accessibility indicator (IUA) was introduced for the first time in MBHG 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 the individual geography’s metadata.This high definition (HD) version is the most detailed geometry, suitable for use in GIS for geometric analysis operations and for the computation of areas, centroids and other metrics. The HD version is aligned to the LINZ cadastre.
