Jacinda Ardern appears to be heading for a landslide win and a second term as prime minister during early vote counting in New Zealand’s election.

With about a third of the votes counted, Ms Ardern’s liberal Labour Party has nearly double the amount of votes of its main challenger, the conservative National Party.
