Labour leader David Cunliffe says he "absolutely" thinks the party can take the Te Tai Tokerau seat from the sitting MP Hone Harawira, with a poll putting the Mana leader ahead by just one percent.
The Maori Television Reid Research poll released last night had Mr Harawira on 38% and Labour candidate Kelvin Davis on 37%.
Asked today if he thinks Labour could take Te Tai Tokerau, Mr Cunliffe said: "Absolutely. I've been saying that all along. Kelvin is running a terrific campaign in Te Tai Tokerau and we're backing him to win."
When asked if he wants to wipe out Internet Mana, he said: "I want to win all seven Maori seats for Labour because Labour is the party that best represents Maori aspirations."
Pressed further, Mr Cunliffe said he would be not particularly concerned if that meant the end of Internet Mana, adding he wants to see Kelvin Davis as the MP for Te Tai Tokerau.
"Look, I've said before that I don't hold with the influence of big money in politics wherever it comes from. That remains my position."
The Maori Party candidate Te Hira Paenga was well back on 9.4% in the poll and Independent MP Clinton Dearlove was on 1.4%.
The poll had Labour leading the party vote on 39% and Internet Mana second on 25%.
Hone Harawira entered Parliament as Maori Party MP for Te Tai Tokerau in 2005 but his resignation caused a by-election in 2011 which he won with a majority of 1117.
