Labour is ahead of National in the latest 1 News Colmar Brunton Poll with the party's support growing to 43 per cent, while National has dropped to 41 per cent.
Since the last poll two weeks ago Labour is up 6 points giving them a level of support not seen since 2006.
Meanwhile National has fallen 3 points to 41 per cent, the lowest poll result for the party since 2005.
New Zealand First is down two points to 8 per cent, the Greens are up one point to 5 per cent and both The Opportunities Party and the Maori Party are down one point to 1 per cent. The result is important for the Greens who fell in the last poll below the 5 per cent threshold needed to return to government.
The result means New Zealand First remains a significant player with both Labour and National needing it to govern. However, on these numbers Labour could form a government with New Zealand First and without the support of the Green Party.
When it comes to who is best for the top job Labour's Jacinda Ardern is the most preferred Prime Minister with 34 per cent, up 4 points on the last poll. National's Bill English is slightly behind on 33 per cent, up 3 points. New Zealand First's Winston Peters is down 3 points to 4 per cent.
The poll is of 1009 eligible voters who were interviewed between August 26-30.
