Electoral roll: list of people who have enrolled to vote. New Zealand has two electoral rolls: the Māori Electoral Roll and the General Electoral Roll.
The general roll is open to all voters. The Māori roll is open to voters of Māori descent. No one can be on both rolls at the same time.
Data calculation/treatment
Enrolment statistics are as at the last day of July 2022.
The population statistics by age group and area are sourced from Stats NZ. Population statistics for new electorates are not available.
Limitations of the data
The proportion of estimated eligible population enrolled can be above 100% as the latest population estimates and projections are based on census data, therefore they are subject to error.
Changes to data collection/processing
From June 2020, enrolment data by electorate reflects the new boundaries and are therefore not always comparable with previous months. 36 electorates are unchanged. The boundaries of 30 general and 5 Māori electorates have been adjusted to some degree, while one new electorate has been created (Takanini).
11 electorates have new or amended names. For more information, please refer to https://elections.nz/democracy-in-nz/historical-events/boundary-review-2019-2020/
