Poll volatility

The latest Roy Morgan poll continues a ‘trend’ of volatility for National and Greens this year and a lack of progress for Labour.

Roy Morgan polls so far this year:

National 43.5 47.0 48.0 48.5 45.5 43.0 48.5 42.5
Labour 33.5 33.0 30.0 30.5 31.5 32.0 28.5 31.0
Greens 12.5 11.0 12.0 10.5 14.0 13.0 11.5 14.5
NZ First 4.0 4.5 5.5 4.5 3.5 5.5 5.5 6.0
Conservative 2.5 1.5 1.0 2.5 1.5 2.5 2.0 0.5
Internet Party 0.5 1.0 1.5
Maori Party 2.0 1.5 0.5 1.5 2.0 1.5 1.0 1.0
Mana Party ^ 1.0 1.0 0.5 ^ 0.5 1.0 1.0
ACT ^ ^ 1.0 1.0 0.5 0.5 0.5 0.5
United Future 0.5 ^ 0.5 0.5 0.5 0.5 0.0 0.5

Rounded to 0.5
^ is less than 0.5

Party summaries with predicted election support range based on current performance:


This is the lowest they have been this year but dropped below this six times last year, with a lowest of 40.5 (April) and a peak of 51 (July).

This volatility suggests a significant number of voters are soft supporters of National, sometimes. National have benefited from a variable and often disappointing performance by Labour but their fold on power looks precarious.

Predicted election range 40-50


Labour have bounced back from a worrying 28.5 in the last poll but at 31 are still failing to impress. Last year’s low was 29 (July) and they peaked at 37 for two consecutive polls in September when Cunliffe took over leadership. Since then they have dropped to mostly low thirties.

While National (and Greens) fluctuate Labour have been more consistent but this is not where they want to be in the polls, totally reliant on Greens,  probably also reliant on NZ First and possibly also needing any mix of of Mana, Internet Party and Maori party.

Predicted election range 25-35


Greens are back to their peak, last reached in November last year but they got to 14 in March. They should be happy with this and look well prepared for the election. Their low last year was 10 in July.

They are benefiting in polls from Labour’s weaknesses but they are relying on Labour to do well enough to give them their first shot at being in Government.

Predicted election range 10-15

NZ First

NZ First are looking good for making the threshold this election. Last year they ranged from 3 (several times) to 6.5 (August) but in the past have done better in elections than polls. They are benefiting from Labour’s weaknesses and National’s missteps.

Predicted election range 5-10

Internet Party

The Internet Party keep nudging up in the third poll and will be satisfied with this progress. The big questions are how much they will climb to and what effect any arrangement with Mana may have. It’s difficult to predict how much big money and a big presence of someone who can’t stand for election will end up impacting.

Predicted election range 0-5

Maori Party

Last year’s range was 0.5 (January) to 2.5 (February and March), this year they have been 0.5 to 2.

The Maori Party has never needed to worry about party vote in the past, they have always got more seats than their proportional allocation by winning electorates. This will be much harder for them this year with some predicting difficulty winning any of them. At least one electorate looks likely but this may bring their party vote into play for the first time. Will they seek party votes?

Predicted election range 1-3

Mana Party

Mana have mostly been 0.5 or 1 this year and last but got to 1.5 in July and dipped below 0.25 this March.

Hone Harawira may or may not be challenged strongly by Kelvin Davis in Te Tai Tokerau. If he retains his electorate they are in.  otherwise everything is up in the air depending on what arrangement they may come to with the Internet Party.

Predicted election range – depends on any arrangement they may make with the Internet Party.


ACT are virtually a new party this year. They have struggled between 0 and 1 last year and so far this year. They have intellectual rather than charismatic leadership so may have to rely on retaining Epsom with a new and relatively unknown candidate. They will have to find something different to impress beyond that.

Predicted election range 0.5-1


United Future have polled 0 to 0.5 last year and so far this year apart from one blip to 1 in March last year. Most of their election efforts will go in to retaining Ohariu which Peter Dunne might manage to pull off but he has had a difficult term. Party support doesn’t look like changing unless they can change dramatically and look like something other than Dunne.

Predicted election range 0.5-1

Conservative Party

Conservatives should be worried about the last poll dropping to 0.5 although they have been there before, in January and September last year. They have reached 2.5 several times including two polls ago.

Colin Craig’s dithering over what electorate to contest, his apparent concession that they need to get 5% and the lack of any connection with National makes their election looking likely to be another expensive folly. Money may pull something out of the hat but there’s no sign of magic yet.

Predicted election range 0.5-3

    Why do the polls still continue to leave out the ‘Aotearoa Legalise Cannabis party’ ?
    I am not a member, but I do know a few. According to many polls, they are receiving at least as many votes as ACT & U/F (0.5 – 1%) if not more !
    Is this a deliberate attempt to keep their main issue ‘off the radar’ ??

    • Most likely lack of public awareness. As far as I know pollsters don’t prompt for parties, they leave it up to respondents to name them. If only one or two remember and name ALCP they will mist the cut.

      It could also be that in elections ALCP is sometimes a protest vote and picks up because of that.

      • OR is it because they get very little media attention ?

        • Media attention is a key part of getting poll and election support.

          Media can be very conservative in what they choose to cover in politics. I’ve had arguments with them about selective coverage, in effect they choose who the public see so are effectively vetting parties and candidates, often based on their need to entertain.

          Even our public broadcaster does this. In the local body elections last year they chose some only candidates to cover “to fit our format”.
