Nearly a year into his leadership, Labour's Andrew Little is still struggling to gain voter support.
The latest ONE News Colmar Brunton Poll shows Mr Little is down to single figures (eight per cent) with Winston Peters in the preferred prime minister stakes, while John Key remains well ahead.
"I'm not particularly fazed by it, I know what the task is ahead of me and I'm getting on and doing it, meeting with Kiwis," Mr Little said.
The National Party remains steady on 47 per cent, while Labour is down one to 31, and the Green Party is on 12.
New Zealand First is up two to nine per cent.
During the polling period, the Government has singed up to the Trans Pacific Partnership Agreement, added red peak to the flag referendum, and faced pressure to do more about the Kiwis being kept in Australian detention centres.
"I think that generally we're just finishing the year quite strong," John Key, who has a 40 per cent approval rating for prime minister, said.
As dairy prices bounce back, voters are also more optimistic about the economy with a nine point rise to 42 per cent.
