Built from the 2025 electorate boundaries used for the 2026 election, matched against Stats NZ statistical areas. Names are the official ones, so a very small settlement may sit inside a larger named locality rather than appear on its own. If you are unsure which electorate you are in, check your address on vote.nz.

Enrolment figures are as at 31 July 2026. The eligible population is the Electoral Commission's own estimate, so “not enrolled” is the gap between that estimate and the roll — not a count of identified people.
Some age bands show above 100% enrolled, which means the roll holds more people than the population estimate for that band. This appears in the Commission's own published table and is not an error here.
The youngest band is consistently the least enrolled: 18 - 24 sits at 60.85% here, against 87.25% across all ages.
