pn812. Covid and the lastest One TV News Colmar Brunton Poll

Colmar Brunton

The latest Colman Brunton Poll largely confirms the results of the two earlier polls by Curia and Talbot Mills reported in my previous post (pn809). Its results, however, are more detailed and the methodology is spelt out, and therefore possibly more reliable. For example:

"Between 6-10th November 2021 1001 eligible voters were polled by mobile phone (501) and online (500). The maximum sampling error is approximately ±3.1%-points at the 95% confidence level. The data has been weighted to align with Stats NZ population counts for age, gender, region and ethnic identification. The sample for mobile phones is selected by random dialling using probability sampling, and the online sample is collected using an online panel."

I'm confident the results are reasonably accurate, at least for the four larger parties, but I have three small reservations: 

1) Those polled by mobile phone were randomly selected, but the online results were chosen from a previously selected panel. More information is needed on how the panel was selected; 

2) "Percentages do not add to 100 due to rounding."  They certainly don't. Party Support totalled 108, possibly close to 10% of those polled.
