2026 NZ election polls explained: how to read them and why they differ
Who runs New Zealand's political polls, what a margin of error really means, why polls disagree, and how poll numbers turn into seats under MMP.
In this guide
Polls are the closest thing to a scoreboard before election day. They're also easy to misread. A two-point move in one poll is often just noise, and different pollsters regularly disagree by several points.
This guide explains how New Zealand's political polls work and how to read them sensibly. For the latest numbers, see our Polls section, which shows every recent poll and an average.
Quick answer
- Most New Zealand polls survey about 1,000 people, giving a margin of error of about ±3 points for a party near 50%.
- For small parties the margin is smaller, about ±1.4 points near 5%, but that's still big enough to decide whether a party crosses the threshold.
- Averages beat single polls. Look at the trend across several pollsters.
- Polls measure party vote intention, which is what decides seats under MMP.
Who runs the polls in 2026?
These pollsters have published regular national polls during the 2026 campaign:
| Poll | Commissioned by | Typical sample |
|---|---|---|
| 1News–Verian | TVNZ's 1News | about 1,000 |
| RNZ–Reid Research | RNZ | about 1,000 |
| The Post–Freshwater | The Post | 1,000 to 1,500 |
| Taxpayers' Union–Curia | Taxpayers' Union | about 1,000 |
| Roy Morgan | Self-published, monthly | about 850 to 1,000 |
| Anacta | Self-published | 1,300 to 1,700 |
Pollsters use different methods: phone, online panels or a mix. They also weight their samples differently by age, gender, region and past vote. That's one reason their numbers differ.
What the margin of error means
The margin of error tells you how far a poll's estimate might be from the true figure, just because of who happened to be sampled. It's usually quoted at the 95% level.
| Party's support | Margin of error, sample of 1,000 |
|---|---|
| 50% | ±3.1 points |
| 30% | ±2.8 points |
| 10% | ±1.9 points |
| 5% | ±1.4 points |
So if a party is on 30% in one poll and 32% in the next, nothing has necessarily changed. The margin also only covers random sampling error. It doesn't cover people changing their minds, people not saying how they'll vote, or a sample that doesn't reflect who actually votes.
Rule of thumb: a change of less than about three points for a big party, or one point for a small party, in a single poll is usually within the noise.
Why polls disagree
- Method. Phone and online polls reach different people.
- Weighting. Each pollster adjusts its raw sample differently.
- Timing. Fieldwork periods differ, and a poll taken over a week can miss a late shift.
- Undecided voters. Pollsters handle "don't know" answers differently, and some report results with undecideds removed.
- House effects. Some pollsters have consistently produced slightly higher or lower numbers for particular parties over time.
That's why poll averages are more reliable. Our average takes the latest poll from each pollster within a recent window, so one pollster can't dominate.
From poll to seats
A poll's party vote numbers can be turned into a seat projection using the same Sainte-Laguë formula used after the election. But there are a few catches:
- The 5% threshold. Parties under 5% get no list seats unless they win an electorate. Polls can't easily predict electorates.
- Electorate wins. Te Pāti Māori won six electorates in 2023 with 3.1% of the party vote. That created two overhang seats. Polls of the party vote alone would have missed that.
- Wasted votes. Votes for parties that miss the threshold don't count towards seats, which slightly boosts everyone else's share of seats.
Try it yourself with our seat builder: pick a poll, move the sliders, and see the 120 seats change.
How accurate have polls been?
New Zealand polls have generally been close on the big parties' support, though individual polls can miss by several points. In 2023 the final polls broadly captured National finishing well ahead of Labour, but the size of individual party votes varied between pollsters. Special votes and electorate results also matter in ways polls don't measure.
Polls on election day
New Zealand doesn't release exit polls, and publishing anything that could influence voters is banned on election day until voting closes at 7pm. The first hard numbers come from the count itself, from about 7:30pm.
Questions and answers
What is the latest NZ poll?
Our Polls section lists every recent poll by date, with links to the original release, plus a poll average and seat projection.
How many people are surveyed in NZ political polls?
Usually about 1,000, though some polls survey 1,300 to 1,700 people.
What does margin of error mean in a poll?
It's the range within which the true result is likely to fall, 95 times out of 100, given random sampling. For a sample of 1,000 it's about ±3 points for a party near 50%.
Why do different polls show different results?
Pollsters use different methods, weighting and timing, and handle undecided voters differently. Averages smooth those differences out.
Are there exit polls in New Zealand?
No exit poll results are published. Election day rules ban publishing anything that might influence voters until 7pm.
