Between September 8 and 15, 1000 eligible Auckland Council voters were polled online, using online panels. After Viv Beck announced her withdrawal, a second poll of 1000 eligible Auckland Council voters was completed in the same manner between September 16 and 20.
The maximum sampling error is approximately ±3.1 percentage points at the 95% confidence level. For candidate support, percentages have been rounded up or down to whole numbers. Undecided voters, non-voters and those who refused to answer are excluded from the data on candidate support. The data have been weighted to align with Stats NZ population counts for age, gender, ethnic identification and education in Auckland Council. The online sample is collected using an online panel.
