The Prime Minister says Labour's not being complacent about the upcoming election despite the opinion polls putting its support at more than 50 percent.
Jacinda Ardern who launched Labour's election campaign in Auckland yesterday says she doesn't for one minute think the party will be able to govern alone after September 19.
Ardern says New Zealand's history tends not to deliver such an outright result and she doesn't believe this election will be any different.
The Prime Minister today has also ruled out a deal in Northland.
New Zealand First's Northland candidate Shane Jones has huge ground to make up if he wants to win the seat and give his party a path back to Parliament without the party crossing the 5 per cent threshold.
A 1 News Colmar Brunton poll has Jones on just 15 per cent support, with National's Matt King, the incumbent, on 46 per cent and Labour's candidate Willow-Jean Prime on 31 per cent.
Jones did not front on TVNZ's Q+A show this morning but admitted he needed to get the "political jack-hammer" out.
