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
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.
The way population estimates are calculated has changed slightly over the years, to get more specific (i.e. limiting visa holders to those who are eligible, including overseas voters etc), so enrolment percentages may not be directly comparable through the years.
Changes to data collection/processing
After the 2023 Census, the Government Statistician worked out how many Māori and general electorates there should be. They also worked out the population quotas – how many people should be in each electorate.
For the 2026 General Election:
- the number of general electorates in the North Island reduces from 49 to 48
- the number of general electorates in the South Island is fixed at 16
- the number of Māori electorates remains unchanged at 7.
From the dataset Enrolment Statistics: Māori enrolment - 1 July 2026, this data was extracted:

About this dataset
Enrolment statistics are published every month by the Electoral Commission showing how many people of Māori descent are currently enrolled to vote broken down by electorate and age.
Purpose of collection
Voters of Māori descent can choose to be on the general roll or the Māori roll. The roll they choose decides which electorate and local council voting area they will vote in.
Method of collection/Data provider
The estimated eligible population is calculated for general electorates and includes those on the general and Māori rolls, because of the geographic overlap of general and Māori electorates.
