This dataset was first added to Stats NZ Geographic Data Service on 08 Apr 2020.

These meshblocks are used as a basis to build the electoral population for each electorate. We calculated the electoral populations from the 2018 Census data using the formula specified in the Electoral Act 1993 and then apply two confidentiality rules: 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.

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. The 2020 electorate boundaries reflect a number of minor technical adjustments to meshblock boundaries, not involving population i.e. to follow the correct line of a river or road. The adjustments are visible in a small number of land and coastal areas where electorate boundaries otherwise unchanged between 2014 and 2020 do not exactly align.

Note: This dataset contains the meshblock MB2020_V2_00 (version 2), a major released version of the annually released meshblock boundaries as at 17 April 2020. This version contains 53,582 meshblocks, or an additional two when compared with MB2020_V1_00 (excluding the 16 non-digitised meshblocks). This version reflects changes made to meshblocks for the 2019/2020 Representation Commission.

These meshblocks are used as a basis to build the electoral population for each proposed electorate. The electoral populations are calculated from the 2018 Census data 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.

These boundaries comprise the 65 general electorates released by the Representation Commission in April 2020. These boundaries will be used for the 2020 and 2023 general elections.

The Representation Commission is convened by the Surveyor-General, its role is to re-draw electorate boundaries to make sure each electorate has about the same number of people. We calculate the general electoral population, number of general electorates, and North Island and South Island electoral quotas using the formula specified in the Electoral Act 1993. When setting the boundaries, the Representation Commission also considers existing boundaries, communities of interest, the infrastructure that links communities (such as main roads), topographical features, and any projected variation in the population of those electorates during their existence.

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.
