'The case for change has been increased' - James Shaw buoyant after special votes give centre left two more seats

Green Party leader James Shaw is delighted with the special vote result which saw the left pick up two more seats, with National losing two.

Mr Shaw was addressing media at Auckland's Stamford Plaza shortly after the special votes result came in.

"Not only did the Greens gain an MP so did Labour, and National dropped two MPs.

"As I said on election night a slim majority of voters voted for change, and that majority has now been extended, the case for change has been increased" Mr Shaw said.

He believes a coalition of three parties is what the New Zealand public voted for and the new results have given the centre left new momentum.

"Over the coming days we are going to be very busy negotiating a new government, I anticipate that Labour will take the lead in negotiations which will start quite soon," the Green Party leader said.

The special votes result means Green Party candidate Golriz Ghahraman will now become an MP, becoming the country's first refugee MP.

Final Result after special votes:

National: 56 seats
Labour: 46 seats
NZ First: Nine seats
Green Party: Eight seats
ACT New Zealand: One seat
