These boundaries comprise the 64 general electorates released by the Representation Commission in August 2025. These boundaries will be used for the 2026 General Election.

This high-definition 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 Representation Commission is convened after each Census to re-draw electorate boundaries to make sure each electorate has about the same number of people. Stats NZ calculates 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.

Electorate names are provided with tohutō/macrons (in UTF-8 format). To support users, additional name fields are also provided in ASCII format.

Meshblocks, which are aggregated to form electorates, are updated annually by Stats NZ. The 2025 electorate boundaries are the result of the review undertaken by the Representation Commission and will be used for the 2026 General Election. A small number of minor technical adjustments, not involving population, have also been made to electorate boundaries, i.e. to align to LINZ cadastral lines (property boundaries).
