An RNZ-Reid poll puts National at 25.9 percent, its weakest since 2020, five weeks before the vote

An RNZ-Reid Research poll published on Tuesday put New Zealand's governing National Party at 25.9 percent, down 3.2 points, its weakest reading in that series since 2020. Labour, the main opposition, fell 1.4 points to 30.8 percent. Bloomberg reported the figures on 5 October. The election is on 7 November, less than five weeks from the publication date.

Both major parties lost ground. The shift, as Bloomberg described it, went to smaller parties. The poll item named Qiulae Wong, leader of the Opportunity Party, in a photograph from Auckland on 29 September. It did not, in the lines available from the wire summary, give the Opportunity Party's share, or the shares for ACT, New Zealand First, the Greens or Te Pāti Māori. Those missing numbers are the gap in the public summary. The headline movement is still clear: National under Prime Minister Christopher Luxon is at a low not seen in this poll since the year Labour won in a landslide under Jacinda Ardern.

What 25.9 percent means under MMP

New Zealand elects its parliament by mixed-member proportional representation. A party vote of 25.9 percent does not translate into a quarter of the seats in a simple way, because list seats are allocated after electorate winners are counted, and because a party needs either 5 percent of the party vote or an electorate seat to enter parliament. A governing party at 25.9 percent cannot form a cabinet alone. National's current government depends on ACT and New Zealand First. A poll that weakens National and also fails to show those partners' numbers leaves the coalition arithmetic unfinished.

Labour at 30.8 percent is ahead of National and still short of a majority. A Labour-led government would need the Greens, Te Pāti Māori, or both, unless smaller parties of the centre take seats that change the sum. The poll's reported move toward smaller parties is the part that can decide 7 November. Without their shares, the 4.9-point gap between Labour and National is a lead, not a government.

The calendar

Five weeks is long enough for a campaign event to move a poll, and short enough that party machines are already allocating broadcast time and electorate visits. Luxon has been prime minister since November 2023, after National assembled a three-party deal. A drop of 3.2 points in one published poll is not an election result. It is a warning to a governing party that its own number, not only the opposition's, is falling.

Reid Research's RNZ series is one of the regular public polls. It is not the only one. A single reading at 25.9 percent becomes a claim about the campaign only if a second poll, taken after this one, shows the same direction. Until then, the usable facts are the ones printed: National 25.9, down 3.2; Labour 30.8, down 1.4; election day 7 November; both large parties losing share to smaller ones.

The open number

The figure that would change the reading is the combined share of the parties that can actually supply the missing seats. If ACT and New Zealand First have held their vote, National's path stays open at a lower plurality. If that vote has gone to the Opportunity Party or to the left bloc, the path narrows. Bloomberg's item did not print those shares. The next poll that does will tell more than another restatement of 25.9.
