Latest opinion poll shows voter loyalty swinging in all directions

New Zealand First is on the rise and seems assured of returning to Parliament in bigger numbers, according to the latest Herald-DigiPoll survey.

And Labour appears to have arrested its steady decline.

National has dropped below 50 per cent for the first time in DigiPoll surveys this year and would need partners to govern. With eight days to go to the election, it could turn out to be a tighter race than the past few weeks have suggested.

Watch: Key: 'It's a clear choice'

"It just shows you how tight the race is going to be, " Prime Minister John Key said last night.

New Zealand First is on 8.1 per cent, up by two points. That would bring in 10 MPs including former MP Ron Mark. That's two more MPs than it got in the last election.

New Zealand First would not hold the balance of power under this poll scenario because National could form a bare majority with just one of its support partners (Act, United Future or the Maori Party) or a comfortable one with all three of them, assuming they are returned.

LEADER POPULARITY

Labour is up slightly to 24.6 per cent. It is the first time in the past six DigiPoll surveys that it has not declined. However, Labour would not be able to form a Government even if it combined with the Greens, New Zealand First, Internet-Mana and the Maori Party.

Their combined vote would be 59 when a majority in a 122-seat Parliament would be 62.

The Conservatives are unchanged on 3.8 per cent and would not make it into Parliament.

Internet-Mana is down by 1.2 points to 2.3 per cent, possibly a reflection of talk of tensions in the alliance, although this result would see Laila Harre and Annette Sykes elected as long as leader Hone Harawira keeps his seat.

The biggest movement has been in the preferred PM ratings.

PARTY DIFFERENCE

The popularity of Mr Key has fallen by 7.3 points to 61.6 per cent, his second lowest rating since becoming Prime Minister in 2008. The popularity of Labour leader David Cunliffe is up by 3.9 points to 17.9 per cent and New Zealand First leader Winston Peters is up by 1.4 to 7.8 per cent.

Mr Key's advice to voters was not to try to second-guess the polls and if they wanted a National-led Government, to vote for National.

Polling began on Thursday last week in relatively clean air - six days after Judith Collins resigned from the Cabinet. An inquiry will determine whether Ms Collins sought to undermine former Serious Fraud Office head Adam Feeley while she was Minister of Justice, as suggested in an email from Whale Oil blogger Cameron Slater. Since her resignation, there has been far less coverage of the Dirty Politics book that was denying oxygen to Opposition parties in the election campaign.
