Greens hit record 16% in 1News poll, but seat maths depends on the method

The Green Party has recorded its best result in a 1News Verian poll, at 16 percent, while National and Labour have both fallen to 28 percent. The poll, released on Monday night and picked up by most major outlets, is the first since Christopher Luxon and Chris Hipkins launched their campaigns. It is one snapshot, not a result, and the election is on 7 November.

What happened

According to 1News, the poll surveyed 1,004 eligible voters between 23 and 27 September, using mobile and online panels. The maximum sampling error is plus or minus 3.4 percentage points, at the 95 percent confidence level.

Party support was: Labour 28 percent (down 2), National 28 percent (down 1), Greens 16 percent (up 4 since August), ACT 11 percent (up 2), NZ First 9 percent (up 1), the Opportunity Party 6 percent (down 2) and Te Pāti Māori 1 percent (steady). 1News says Labour's number is its lowest since February 2024.

For preferred prime minister, Christopher Luxon is on 19 percent (up 2), Chris Hipkins on 14 percent (down 1) and Greens co-leader Chlöe Swarbrick on 8 percent (up 2). The Spinoff reported that 13 percent of voters were undecided.

The seat maths is less simple than the headlines

Headlines say a Labour, Greens, Te Pāti Māori and Opportunity grouping would hold 65 seats against 59 for National, ACT and NZ First. That figure is real, but it rests on an assumption. 1News published a separate explainer setting out two ways of turning the vote into seats.

In the first, Te Pāti Māori keeps the four Māori electorates it holds now and the Te Tai Tokerau Party wins one. Neither party's vote share earns those seats, so Parliament grows to 124 through "overhang". Under that count the right holds 59, Labour, Greens, Te Pāti Māori and Te Tai Tokerau hold 58, and Opportunity holds 7. A majority is 63.

In the second, Parliament stays at 120 and Te Pāti Māori gets only one seat. National and Labour have 34 each, the Greens 19, ACT 14, NZ First 11, Opportunity 7 and Te Pāti Māori 1. A majority is 61. Adding up the left grouping there gives exactly 61.

The point in both versions, as 1News puts it, is that neither bloc reaches a majority without the Opportunity Party. Some coverage runs the 65 figure without saying how narrow the margin is, or that a small change in the share of the vote or in electorate results could move it. The 3.4 point error margin also applies to each party, so gaps of a few points between parties are within the noise.

The Spinoff notes that the left grouping's path depends on whether National is willing to work with Opportunity. It cites the Herald-Motu Poll of Polls giving that scenario a 43.2 percent chance, and says the model assumes no overhang. Winston Peters was quoted saying "The polls are trash."

What it means for you

A poll does not change any law, tax or service. What it changes is how much bargaining power smaller parties may have after the election, and that shapes which promises get delivered. Both major parties are leaning on money-in-your-pocket pledges. Luxon framed the choice as National with "no new taxes" against Labour and its "radical mates". Labour has announced a plan to cut student loan balances, and Hipkins told a breakfast interview he would reverse recent pay equity changes within the first 100 days of a Labour-led government.

For a household, the practical questions are what a coalition would agree to on tax, wages, student debt and services, and what it would cost. Those trade-offs are normally settled in coalition talks after voting, not before. Swarbrick said the Greens want real portfolios rather than a minor role, which suggests any deal could involve more negotiation than in recent terms.

Who's responsible and what they say

Poll numbers belong to the pollster and the media that commission them. 1News and Verian published their method. Party leaders have responded in campaign mode: Swarbrick called the result "pretty cool" while stressing that voters decide, and Luxon has focused on tax. The Herald reported that Labour dismissed National's tax claims. Opportunity has not commented publicly on the seat maths.

What happens next

Treasury is due to release its Pre-election Economic and Fiscal Update today, which will give the first official picture of the books since Budget 2026 and will test the costings behind campaign promises. Advance voting opens on 26 October.

Our take

Nobody has a majority on these numbers. A 65 to 59 lead sounds decisive, but under one counting method the left grouping's edge is a single seat, and it depends on a party polling 6 percent.

Any single poll is a rough guide with a wide margin. The better test is what each party will actually agree to when it has to compromise, and what that costs. That is a fair question to put to every side before 7 November.
