New Zealand’s election: why 67 projected seats do not settle who governs

New Zealand’s unfinished election count can change more than who wins a close local race: it can change the size of Parliament itself. That makes the next government’s position harder to read than a simple tally of seats won and lost.

After voting on November 7, National, ACT and New Zealand First together have 67 projected seats: 42 plus 13 plus 12. The projected Parliament has 131 members, making 66 the threshold for an outright majority. Their combined tally is one seat above that threshold, according to calculations from the Electoral Commission’s preliminary results.

The official-count process was scheduled to begin on November 8. Approximately 399,365 special votes require checks and counting, and ordinary votes are recounted too. Official results are scheduled for November 27.

The distinction between votes and seats is already visible in the two largest parties’ results:

Labour has slightly more party votes, yet National has six more projected MPs. The explanation lies in how local victories interact with proportional representation.

Voters have two votes: one helps choose their local representative, while the other determines a party’s overall share of seats. A party qualifies for proportional allocation by receiving at least 5% of the party vote or winning an electorate. Local winners fill its allocation first; candidates from its ranked party list fill the remaining places. These are the Commission’s rules for electing MPs.

But a party keeps every electorate it wins, even if those victories exceed its proportional entitlement. The additional seats create an overhang, enlarging the normally 120-member Parliament without reducing other parties’ allocations. National’s 42 projected seats are all electorate victories. Labour’s 36 comprise 21 local winners and 15 list MPs.

This also explains why two similarly close local contests can have different national consequences.

In Wairarapa, National’s Mike Butterick leads Labour’s Kieran McAnulty by 139 votes. In Wellington Bays, Labour’s Craig Renney leads the Greens’ Julie Anne Genter by 140. Those margins were reported by 1News on November 8.

With Labour and the Greens both projected to receive list seats, a different Wellington Bays winner could change the local representative while list allocations adjust to preserve each party’s overall entitlement. A National loss in Wairarapa could instead remove an overhang seat and shrink Parliament.

That moving denominator matters. Losing one seat would not automatically erase the three parties’ majority. In a hypothetical scenario where National lost one overhang electorate to Labour and everything else stayed fixed, their combined tally would fall to 66—but Parliament would shrink to 130. The majority threshold would still be 66. This is an illustration of the rules, not a forecast: the remaining party votes can also change proportional allocations.

Special votes are not simply ballots arriving late. People cast them when they are absent from the printed roll at their voting place—for example, because they voted outside their electorate, voted overseas or enrolled close to election day. Officials return these ballots to the relevant electorate and check declarations for enrolment and eligibility before counting them. The official-count explanation also describes checks for possible multiple voting and the hand recount of ordinary ballots.

Neither a reversal nor a final majority is established by the preliminary figures. November 27’s scheduled results will provide the checked party-vote allocations and electorate winners; government formation also involves negotiations between parties.
