Various organisations commissioned opinion polls for the [[2017 New Zealand general election]] during the term of the [[51st New Zealand Parliament]] (2014–2017). [[Roy Morgan Research]] polled monthly, with [[MediaWorks New Zealand]] (''3 News''/''[[Newshub]]'' Reid Research) and [[Television New Zealand]] (''[[One News (New Zealand)|One News]]'' [[Colmar Brunton]]) polling less frequently. The last ''[[The New Zealand Herald]]'' (Herald Digipoll) was in December 2015, and [[Fairfax Media]] (Fairfax Media [[Ipsos]]) discontinued their poll after the [[2014 New Zealand general election|2014 election]]. The sample size, margin of error and confidence interval of each poll varied by organisation and date, but were typically 800–1000 participants with a [[margin of error]] of just over 3%.
The previous Parliament was elected on Saturday 20 September 2014. The 2017 general election was held on Saturday 23 September 2017.<ref>

==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.
===Graphical summary===
The first graph below shows trend lines averaged across all polls for parties that received 5.0% or more of the party vote at the 2014 election. The second graph shows parties that received between 1.0% and 4.9% of the party vote or won an electorate seat at the 2014 election.
[[File:NZ opinion polls 2014-2017-majorparties.png|thumb|left|800px|Summary of poll results given below from the election result 20 September 2014. For simplicity, only political parties that received 5.0% or more of the party vote at the 2014 election are shown. Lines give the mean estimated by a [[Local regression|LOESS smoother]] (smoothing set to span = 0.35), with shaded grey areas showing the corresponding 95% confidence interval for the estimate. Figures to the right show the estimate from the smoothing line at the date of the most recent poll, with 95% confidence interval. ]]

===Internal polls===
These polls are typically unpublished and are used internally for Labour (UMR) and National (Curia). Although these polls are sometimes leaked or partially leaked, their details are not publicly available for viewing and scrutinising. Because not all of their polls are made public, it is likely that those which are released are cherry-picked and therefore may not truly indicate ongoing trends.
