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 is a member of the Board of the Taxpayers' Union and also a Director of Curia Market Research Ltd.

The Taxpayers’ Union – Curia Poll was conducted from Sunday 2 to Wednesday 5 April 2023. The median response was collected on Tuesday 4 April 2023. The sample size was 1,000 eligible New Zealand voters: 800 by phone and 200 by online panel. The sample selection for the phone panel is from those who are contactable on a landline or mobile phone selected at random from 15,000 nationwide phone numbers. 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.

This poll should be formally referred to as the “Taxpayers’ Union – Curia Poll”.
