Voters in New Zealand finally get to cast their vote in their national elections this Saturday — bringing to an end a tightly-fought contest.

After pollsters gave the Labour Opposition no chance of taking government from the National party at the start of the campaign, Labour has staged a remarkable comeback under its new charismatic new leader, 37-year old Jacinda Ardern who successfully harnessed a mood for change.

But in the past few days, some polls are detecting voters may be heading back to the government, and its leader Prime Minister Bill English.

But the campaign isn't over yet.
