These meshblocks are used as a basis to build the electoral population for each proposed electorate. The electoral populations are calculated using the formula specified in the Electoral Act 1993 and are confidentialised using Stats NZ confidentiality rules. The rules applied to the electoral populations are suppression of all unrounded counts below six (displayed as: ‘-999’) and random rounding to base three. Since the electoral populations of each meshblock are randomly rounded, the count for each meshblock could be different to the raw total by up to two when compared with the total electoral population for meshblocks from another source. Land Information New Zealand (LINZ) and Stats NZ are the data custodians.
Data is provided with tohutō/macrons (UTF-8 format). To support users with the compatibility of the data and the applications they might be using, additional fields are also provided in ASCII format.
Meshblocks, which aggregate to form electorates, are updated annually by Stats NZ. Since the 2013/14 boundary review, a number of meshblock boundaries that coincide with electorate boundaries have been adjusted to a better position i.e. to follow the correct line of a river or road. These minor adjustments do not affect any populations. The adjustments are visible in a small number of land and coastal areas where the current and proposed boundaries do not exactly align. The Representation Commission will be asked to approve these minor adjustments when they fix the boundaries in 2020.
