KEY POINTS:
The latest Herald-DigiPoll survey shows National with 50.3 per cent support in the race for the party vote and in a position to govern alone if results were translated into votes at an election.
Labour is 13.5 percentage points behind on 36.8 per cent support. The gap is now twice the 6.5 per cent lead National enjoyed in the Herald's July survey.
The Greens crossed the 5 per cent threshold of party support in the Herald poll for the first time since May. NZ First remained below it.
