Notes
The scientific poll was conducted by Curia Market Research and commissioned by the New Zealand Taxpayers’ Union. The full polling report is being released exclusively to members of our Taxpayer Caucus. As is well known, but for full disclosure, David Farrar co-founded the Taxpayers' Union and previously served on its board. He is also a Director of Curia Market Research Ltd.
The Taxpayers’ Union – Curia Poll was conducted from Sunday 03 and Tuesday 05 August 2025. The median response was collected on Monday 04 August 2025.
The target population is adults aged 18+ who live in New Zealand and are eligible and likely to vote. The sample population is adults aged 18+ who live in New Zealand and are eligible and likely to vote who are contactable on a landline or mobile phone or online panel. 1,000 respondents agreed to participate, 800 by phone and 200 by online panel. The number of decided voters on the vote questions was 909. There were 62 (6.2%) undecided voters and 29 (2.9%) who refused the vote question.
A random selection of 10,000 NZ phone numbers (landlines and mobiles) and a random selection from the target population from up to three global online panels (that comply with ESOMAR guidelines for online research). If the call is to a landline, the person who is home and next has a birthday is asked to take part. Those who take part through an online panel are excluded from further polls on the same topic for six months.
Multiple call-backs occurred to maximise the response rate. Those who said they were unlikely or very unlikely to vote were excluded.
The poll was part of a wider omnibus survey for multiple clients. Questions on voting sentiment are asked before any other questions. The questions were asked in the order they are listed.
The results are weighted to reflect the overall voting adult population in terms of gender, age, and area.
Based on this sample of 1,000 respondents, the maximum sampling error (for a result of 50%) is +/- 3.1%, at the 95% confidence level. Results for sub-groups such as age and area will have a much higher margin of error and not seen as precise.
