What happens in a boundary review?

At the start of the boundary review, the Representation Commission meets to agree on the proposed boundaries and electorate names that will go out for public consultation.

Each electorate has about the same number of people

The Representation Commission makes sure each electorate has about the same number of people. The number of people in each electorate cannot be more than 5% larger or 5% smaller than its population quota.

The population quotas are the average populations of North Island, South Island and Māori electorates.

The Representation Commission also considers other factors

The Representation Commission also considers:

  • existing electorate boundaries
  • communities of interest — including iwi affiliations in Māori electorates
  • the infrastructure that links communities, such as main roads
  • topographic features such as mountains and rivers
  • projected variations in electoral populations over the next 5 years.

The Commission also makes sure the names of electorates are still relevant.

The public can have their say on the boundary review

The public can have their say on the proposed boundaries and names. Public consultation happens in three stages:

  • written objections
  • written counter-objections
  • public hearings. 

We’ll publish all objections and counter-objections.

New boundaries take effect when the current Parliament dissolves

The Representation Commission will consider all objections and counter-objections, and then produce its final report. The new boundaries take effect when the current Parliament dissolves.
