Opinion poll trends for the 2026 New Zealand General Election
Analysis to 27 September 2026
Dr Lindsay R Morris
Based on opinion poll modelling to 27 September 2026, National–ACT–New Zealand First collectively held a majority of seats in 23.4 percent of simulations while Labour–The Greens–Opportunity held a majority in 34.8 percent of simulations.
This short report provides key facts and figures based on opinion poll data analysed for seven political parties ahead of the 2026 New Zealand General Election (to be held on 7 November 2026). The reported estimates reflect modelled trends in polling data and should be interpreted as indicative of current public opinion rather than forecasts of the final election result.
The seven political parties reported on here are:
- The New Zealand National Party (National) with 48 seats in the current parliament
- The New Zealand Labour Party (Labour) with 34 seats
- The Green Party of Aotearoa New Zealand (The Greens) with 15 seats
- ACT New Zealand (ACT) with 11 seats
- New Zealand First with 8 seats
- Te Pāti Māori with 5 seats
- The Opportunity Party (Opportunity) with no seats.
Currently, there is one independent MP in Parliament.
National, ACT, and New Zealand First currently govern as a coalition government, and are generally considered to be on the centre-right of the political spectrum. Labour, The Greens, and Te Pāti Māori are generally considered to be on the centre-left of the political spectrum. Opportunity are generally considered to be in the centre of the political spectrum.

Seat allocations assume that each party retains at least one electorate seat it won in the 2023 election, allowing it to remain represented in Parliament even if its party vote falls below 5 percent. Because seat estimates are reported separately for each party and then rounded to whole numbers, their totals may not sum exactly to 120.

Preferred Prime Minister results were analysed across five of six polling organisations despite minor differences in question wording. Opinion polls published by The Post–Freshwater Strategy were excluded because they only allow respondents to choose between Chris Hipkins and Christopher Luxon, inflating their percent support.
Government approval as of 27 September 2026
Estimated net government approval is -17.3 (± 3.8) and is significantly decreasing by 0.3 points per month.
Polling organisations
Opinion polling data is collected by seven polling organisations at different frequencies. Since 6 November 2023:
- the most recent poll was published by 1 News–Verian on 27 September 2026
- the next poll is estimated to be published by Roy Morgan before 27 September 2026
- the most frequent polling organisation is ****, who
publish polls with a median frequency of days
- the least frequent polling organisation is ****, who publish polls with a median frequency of days.
Polling organisations that conduct surveys more frequently can detect shifts in public opinion sooner than those that poll less often. This helps identify emerging trends, short-term fluctuations, and changes in voter sentiment between elections. Less frequent polling may miss these rapid changes, making trend estimates less responsive.
| Polling organisation | Most recent poll | Polls | Median frequency | Next poll † |
|---|---|---|---|---|
| 1 News–Verian | 27 September 2026 | 17 | 56.0 days | 6 December 2026 |
| The Post–Freshwater Strategy | 11 September 2026 | 7 | 103.5 days | – |
| Anacta | 10 September 2026 | 1 | NA days | – |
| Taxpayers’ Union–Curia | 3 September 2026 | 34 | 30.0 days | 6 October 2026 |
| Roy Morgan | 23 August 2026 | 34 | 28.0 days | 27 September 2026 |
| RNZ–Reid Research | 21 August 2026 | 7 | 84.5 days | – |
| Talbot Mills | 11 August 2026 | 21 | 33.0 days | 10 October 2026 |
| † Next poll date is estimated based on the upper bound of a 95% confidence interval for the median days between polls, using historical polling frequency. Currently, there are not enough published polls to estimate when the next Anacta polls will be published. |
ACT
The estimated odds of someone saying they will vote for ACT when responding to a Roy Morgan or Taxpayers’ Union–Curia poll are higher than that of someone saying they will vote for ACT when responding to a Talbot Mills poll (holding all other modelled factors constant). The estimated odds for other polling organisations were not significantly different to that of Talbot Mills.
Labour
The estimated odds of someone saying they will vote for Labour when responding to a 1 News–Verian, Taxpayers’ Union–Curia, or Roy Morgan poll are lower than that of someone saying they will vote for Labour when responding to a Talbot Mills poll (holding all other modelled factors constant). The estimated odds for other polling organisations were not significantly different to that of Talbot Mills.
National
The estimated odds of someone saying they will vote for National when responding to a 1 News–Verian poll are higher than that of someone saying they will vote for National when responding to a Talbot Mills poll (holding all other modelled factors constant).

Trend methodology
Generalised additive models (GAMs) were used to estimate underlying trends in party percent support over time. GAMs allow trends to change smoothly over time rather than assuming a straight-line increase or decrease. Models were fitted using a beta distribution, which is appropriate for percentages because it constrains estimates to the 0–100% range. Smooth functions of time were specified using thin plate regression splines, with the basis dimension (k) set to 0.8 times the number of polls to allow sufficient flexibility while reducing the risk of overfitting. Smoothing parameters were estimated using restricted maximum likelihood (REML).
Trend likelihoods are reported as significant when the probability of an increasing or decreasing trend is above 95 percent and not significant when no trend direction can be determined or the probability is 95 percent or less.
