There has been a surge in support for the Maori Party in our latest 1 NEWS Colmar Brunton Political poll, with the Party up three percentage points to four per cent.

That's its highest ranking since 2008.

There's little change for the major parties though with National steady this month on 46, Labour also unchanged on 30 and the Greens holding their ground on 11 per cent.

New Zealand First has however slipped three per cent to eight per cent this month.

None of the other minor parties have made it to one per cent. However Gareth Morgan's The Opportunities Party, has made its first appearance in the 1 NEWS poll, at 0.4 per cent.

The surge in support for the Maori Party comes after it secured a peace deal with Hone Harawira's Mana party and won the backing of the Maori King in the Hauraki Waikato electorate.

Co leader Te Ururoa Flavell says he believes the rise in support is a sign that Kiwis are becoming more aware of the party's "pragmatic" approach to politics.

According to tonight's poll on four per cent the Maori Party would have five MPs in Parliament and that could potentially see them holding a King maker role after the election.

National for example would be able to form a government on this poll result using its just existing support partners of Act, United Future and the Maori Party. It would not need New Zealand First.

Labour and Greens on the other hand could form a government with the Maori Party's support but would also need the support of New Zealand First as well.

Meanwhile in the preferred Prime Minister stakes Bill English has taken a hit this month down from 31 to 25 per cent.

In second equal place at nine per cent are Winston Peters up one and Labour's new deputy leader Jacinda Ardern who's up five per cent this month also nine per cent.

Andrew Little is back at seven per cent.

Meanwhile tonight's poll also asked whether people oppose or support the Government's proposal to hike the age of Superannuation eligibility to 67 in 20 years.

Fifty per cent support the move and 40 per cent oppose it and eight per cent don't know.
