Fifteen Seats Could Decide New Zealand's Election

Published 2026-10-28

A new 1News analysis has identified 15 electorate seats that could play a key role in deciding the outcome of the election. The seats are important because of how New Zealand's voting system works.

New Zealand uses the Mixed-Member Proportional (MMP) system. Voters cast two votes: one for a local electorate candidate and one for a political party. Each party's share of seats in Parliament is normally based on its party vote. However, if a party wins more electorate seats than its party vote would give it, it keeps the extra seats. These extra seats are called overhang. The analysis notes that every electorate seat National wins could add to the size of any overhang.

The report also suggests that the Labour Party hopes to benefit from changes in support for National. Labour is expected to look for gains in seats where National's support has fallen, and it hopes this shift will be large enough to change the result in some electorates. The analysis does not predict the final result, so the closest seats will be watched carefully as the election approaches.

For voters, the analysis is a useful guide to the electorates where local races may be most competitive. Because a small change of votes in a few seats can affect which party or coalition forms the government, these areas may attract a lot of campaign activity in the coming weeks. Readers who want to understand the result should look at both the electorate races and the party vote, since both affect how many seats each party finally holds in Parliament.
