Mount Albert's Greens candidate says the narrow margin in the seat shows elections are no longer two-horse races.

Labour's Helen White has won on early numbers by just over 100 votes.

It's traditionally a Labour stronghold, previously held by Jacinda Ardern, David Shearer, Helen Clark - and Michael Savage.

White's blaming her slim-win on the Greens splitting the vote.

Ricardo Menendez-March says his Party's proud of its record result.

"No one, not the Greens, not National or Labour, can take any electorate for granted."
