The first polticial poll of 2013 shows National widening its lead over Labour but little change in the balance of power between the Right and Left blocs.
The Roy Mogan survey, released tonight, shows support for National up 0.5 percentage points since mid-December at 46 per cent.
Labour was down two at 31.5 per cent in the poll, which is seen as more volatile than other major poltiical surveys.
The Greens were at up one at 12 per cent but NZ First, level on 5 per cent, could hold the balance of power on the numbers in the survey.
Among National's current support parties ACT was down 0.5 at 0.5 per cent and the Maori Party was up 0.5 at 2 per cent.
Results for other minor parties saw Mana on 0.5, down from 1 per cent, and United Future also on 0.5 per cent. The Conservative Party, which does not have any seats in Parliament now, won the backing of 1.5 per cent.
The telephone poll of 1865 respondents was taken between January 2 and 18.
