For voters who were unsure which party they would vote for, 18 per cent said they were less likely to vote Labour if a Te Pāti Māori coalition was the only one on the table, 7 per cent said they were more likely to vote Labour and 61 per cent said it made no difference.
The poll also looked at the impact on National of a NZ First coalition.
NZ First has ruled out working with Labour, but a potential National-NZ First deal is on the table if NZ First makes it into Parliament.
Fifty-three per cent of voters said an NZ First coalition with National made no difference to their propensity to vote blue, while 14 per cent said they were more likely to vote National.
Twenty one per cent said they were less likely to vote National, giving a potential NZ First coalition a net -7 per cent impact on National.
National voters were 16 per cent more likely to vote National if an NZ First coalition was the only path to power, while for 65 per cent of National voters it made no difference.
Fourteen per cent of National voters were less likely to vote National if an NZ First coalition was the only thing on the table.
Unsure voters were 25 per cent more likely to vote National if NZ First were in the tent, while for 51 per cent it made no difference.
Just 8 per cent were less likely to vote National.
The figures have added significance after Christopher Luxon ruled out working with Te Pāti Māori after the election, bargaining that National stood more to gain by lumping Te Pāti Māori with what he calls the “coalition of chaos” than any post-election path to power is worth.
The poll was taken between May 31 and June 6, 2023, and conducted using a sample of 1000 respondents. The margin of error is 3.1 per cent.
