Most seats have been decisively won with only one electorate having a margin of less than 1000 votes.

The closest race was in Ohariu where Labour's Greg O'Connor is 679 votes ahead of National's Brett Hudson.

In 2014 there were four electorates with a margin of less than 1000.

In 2011, voting in the Waitakere electorate was so close the winner changed twice after election night.
