National's support has fallen in the latest political poll, but it's not losing voters to the opposition.
National's support in the 3News poll was at 46.3 per cent, down 3.2 percentage points but still comfortably leading Labour, which was on 32.2 per cent.
Labour's support was 1.2 percentage points higher than the previous poll, but it was tempered by a 1.6 percentage point fall for the other main party of the left, the Greens, who were on 10.4 per cent.
The biggest riser in the poll was the Conservative Party, up 1.7 percentage points to 2.8 per cent, well below the 5.0 per cent threshold but high enough to bring in more than one MP if they were to take an electorate seat.
Mana was up 1.1 percentage points to 1.3 per cent, enough for another MP if Hone Harawira retains his electorate seat.
NZ First was up 0.3 to 4.2 per cent, below the threshold. The Maori Party was at 1.2 per cent, with ACT at 0.8 per cent and United Future barely registering at 0.1 per cent.
The poll predicted National would be one seat short of governing alone and would need the help of United Future or the Maori Party, though it predicted ACT would lose Epsom and not return to Parliament.
Prime Minister John Key was still ahead as preferred leader with 40.9 per cent support, down 1.1 percentage points but well clear of Labour's David Cunliffe on 10.8 per cent.
The poll of 1000 people took place between November 3 and 7 and has a margin of error of 3.1 per cent.
