Opinion polling for the 2014 New Zealand general election

Opinion polling for the 2014 New Zealand general election has been commissioned throughout the duration of the 50th New Zealand Parliament by various organisations. The five main polling organisations are Fairfax Media (Fairfax Media Ipsos), MediaWorks New Zealand (3 News Reid Research), The New Zealand Herald (Herald Digipoll), Roy Morgan Research, and Television New Zealand (One News Colmar Brunton). The sample size, margin of error and confidence interval of each poll varies by organisation and date.

Party vote and key events
Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between survey organisations.
