Final Roy Morgan New Zealand Poll shows Labour/Greens (60 seats) with Maori Party support favoured to win knife-edge
election over National/NZ First/Act NZ (58 seats).
In September support for a potential Labour/Greens coalition has increased to 48.5% (up 7% from mid-August 2017) now
well ahead of incumbent National on 40% (down 2.5%).
• National remains (just) the most popular party with support of 40%, however this is a large drop of 7% since the
2014 Election which looks set to cost the party a chance of leading a new Government after next week's election.
• Labour's support has surged on the back of new Leader Jacinda Ardern to 39.5% - up 14.4% since the 2014
Election, and up 7% since mid-August just after Ardern became Leader.
• Greens support of 9% is down 1.7% since the Election, but unchanged on a month ago, just after former Leader
Metiria Turei resigned her job in late July.
• The surge in support for Labour has come at the expense of New Zealand First with support down 2.7% from the
election to 6% and now just above the 5% threshold for winning list seats. Support for New Zealand First has plunged by
5.5% from last month.
• Overall support for the governing National-led coalition was down 6.8% from the election to 42.5% with support
for National’s coalition partners virtually unchanged: Maori Party on 2% (up 0.7%), Act NZ on 0.5% (down 0.2%) and
United Future on 0% (down 0.2%) with long-time party leader Peter Dunne not recontesting his seat at this year’s
election.
• Support for the parties currently outside Parliament was 3% led by new party The Opportunities Party (T.O.P.)
unchanged on 2% with the Conservatives on 0.5% - down a significant 3.5% since the 2014 New Zealand Election.
2017 New Zealand Election Seats Projection
Labour (49 seats); Greens (11 seats) & Maori Party (2 seats): Total 62 seats cf. National (50 seats); NZ First (7 seats) & Act NZ (1 seat): Total 58 seats. See below for more detail.
On the eve of the 2014 New Zealand Election Roy Morgan projected a narrow win for the National/Maori Party/Act NZ/ United Future coalition on 63 seats cf. Labour/Greens/NZ First on 58
seats. The final result was 64 seats cf. 57 seats.
New Zealand Roy Morgan Government Confidence Rating down in September
The Roy Morgan Government Confidence Rating decreased slightly, down 2pts to 137pts in September with 62% of NZ electors
(down 0.5% from August) saying NZ is ‘heading in the right direction’ cf. 25% of NZ electors (up 1.5%) that say New
Zealand is ‘heading in the wrong direction’.
Gary Morgan, Executive Chairman of Roy Morgan Research, says the Maori Party’s positive reaction to new Labour Leader
Jacinda Ardern looks to be decisive in an election finally balanced between Labour/Greens and National/NZ First/Act NZ:
“The momentum in New Zealand’s election campaign is clearly with the Labour Party led by new Leader Jacinda Ardern – and
Labour on 39.5% - up 7% since early August are now virtually level with governing National on 40% - down 2.5% over the
past month.
“However, the narrow gap between the major parties means the final outcome of the election will be decided by the second
string parties – and it is here that Labour has a decisive edge.
“Labour’s natural allies the Greens have held steady on 9% over the past month following the resignation of former
leader Metiria Turei while the vow by Labour Leader Jacinda Ardern to cut New Zealand’s net immigration by up to 30,000
appears to have significantly dented support for the traditionally anti-immigration New Zealand First – down 5.5% in a
month to 6%.
“Today’s in-depth examination of the concerns of New Zealanders show electors continue to regard Poverty and the gap between rich and poor (16%) and the housing issues of House prices & Housing affordability (16%) and Housing shortages & Homelessness (10%) as the key issues the new Government needs to tackle.
“Ardern’s vow to tackle housing issues by removing ‘speculators unfair tax advantages’, ‘stopping foreign buyers who
have no interest in New Zealand buying existing homes’, ‘getting on and building more houses’ – at least 10,000 extra
houses a year and cutting New Zealand’s net annual immigration by up to 30,000 people per year address all the key
issues and since becoming Leader Labour has taken support from National (down 3% since July), Greens (down 4.5%) and New
Zealand First (down 2%).
“However despite this momentum, today’s final Roy Morgan New Zealand poll of the election shows the election result is
likely to be tight with a Labour/Greens coalition needing Maori Party support to hold a clear majority in Parliament.
Based on today’s figures a Labour/Greens/Maori Party coalition is projected to hold 62 seats in the 120 seat Parliament
compared to 58 seats for National/New Zealand First/Act NZ.”
Electors were asked: “If a New Zealand Election were held today which party would receive your party vote?” This latest New Zealand Roy Morgan Poll on voting intention was conducted by telephone – both landline and mobile – with
a NZ wide cross-section of 866 electors during August 28 – September 10, 2017. Of all electors surveyed 5% (down 1.5%)
didn’t name a party.
Margin of Error
The margin of error to be allowed for in any estimate depends mainly on the number of interviews on which it is based.
The following table gives indications of the likely range within which estimates would be 95% likely to fall, expressed
as the number of percentage points above or below the actual estimate. The figures are approximate and for general
guidance only, and assume a simple random sample. Allowance for design effects (such as stratification and weighting)
should be made as appropriate.
