New Zealand uses Mixed-Member Proportional (MMP) voting: every voter casts two votes each election. The electorate vote below elects this seat's local MP by simple plurality (the same "winner by margin" model this site uses everywhere) — it does not by itself determine how many seats a party holds in Parliament. The separate party vote, shown further down, is what decides each party's overall share of Parliament, and often goes to a different party than the local electorate vote does.
