To get the data needed for the boundary review, the Government Statistician worked out how many Māori and general electorates there should be for the 2020 and 2023 general elections. They also worked out the population quotas – how many people should be in each electorate.
For the 2020 and 2023 elections, the number of:
- general electorates in the South Island is fixed at 16
- general electorates in the North Island increases from 48 to 49
- Māori electorates remains unchanged at seven.
The population quotas in those electorates will be:
- 65,458 people for South Island general electorates
- 64,899 people for North Island general electorates
- 67,582 people for the Māori electorates.
The boundaries of eight South Island general electorates, eleven North Island general electorates and three Māori electorates will have to change as there are either too many or too few people living in those areas.
The Representation Commission will use the Government Statistician’s report to conduct the boundary review.
