Labour has opened up a new front in its struggling campaign for re-election in New Zealand, releasing a climate manifesto to reinforce its green credentials.
The latest poll has Labour heading towards opposition, with 26.5 per cent of voter support compared with 39 per cent for the centre-right National.
The Newshub-Reid Research poll has the Greens surging to 14.2 per cent, which would see the left-wingers double their MPs in the party's best-ever result.
