Reviewing Electorate Boundaries

Under the Electoral Act, electorate boundaries must be redrawn after each five-yearly population census and Māori Electoral Option. 

The Representation Commission is the independent statutory body that reviews and redraws New Zealand’s electorate boundaries in accordance with the rules in the Electoral Act for deciding the boundaries. It needs to ensure that electorates have reasonably equal population size and reflect the communities within them.

For some voters, a change to the boundaries may mean that the electorate a voter lives in changes. If so, the voter may find that the candidates standing to become members of Parliament in their new electorate may be different to the candidates standing in their previous electorate.

It may also mean that the name of their electorate changes, even if they are not affected by changes to boundaries.
