How the pollsters did
These tables are from Grumpollie. The Herald DigiPoll was closest for National, One News Colmar Brunton for Labour, Herald Digipoll for Greens and NZ First.
On the provisional results, the Herald DigiPoll was exceedingly accurate. A wee way back were One News Colmar Brunton, Roy Morgan and Fairfax Ipsos. 3 News Reid Research was noticeably further out.
However overall not too bad a result overall for the public pollsters. Grumpollie notes:
- Well done DigiPoll.
- Looking at these results, I see no evidence of the ‘National bias’ that some people talk about.
- If there is any poll bias, it appears to be toward the Green Party.
- The landline bias/non-coverage issue is a red herring.
Hopefully we’ll hear less now of how the landline polls over estimate National!
