Context

This prediction market asks whether the National Party will win the most seats in the New Zealand House of Representatives in the 2026 general election. The market resolves based on the official results and consensus reporting of which party secures the greatest number of seats, with tie-breakers relying on party list votes or alphabetical order if necessary.

Following the election held on November 7, 2026, early reports indicate the race is too close to call with National and Labour neck and neck. Voters have turned toward minor parties, and New Zealand faces a period of political uncertainty as the final outcome may depend heavily on special votes.

Leaders such as Christopher Luxon have pointed to potential pathways to government, while several prominent MPs face uncertain futures as votes continue to be tallied. Final government formation could take weeks.
