Labour's candidate Meka Whaitiri has won the Ikaroa-Rawhiti by-election with a 1761 vote majority.
However, the news was not as good for John Key's support partner, the Maori Party: Nikora was almost 400 votes ahead of Maori Party candidate Na Raihania, a result that will disappoint the Maori Party. Raihania has had to campaign with leadership issues plaguing the party.
At Whaitiri's headquarters, Labour supporters were jubilant. Leader David Shearer arrived at about 8pm and was greeted with loud cheers.
In 2012 Parekura Horomia held onto the seat with 60 per cent support in the candidate vote, while about 50 per cent voted for Labour with their party votes.
Turnout appears to have been low in a seat with more than 33,000 enrolled voters.

10, 519 people voted
Meka Whaitiri - Labour Party 4368 votes
Te Hamua Nikora - Mana 2607 votes
Na Rongowhakaata Raihania - Maori Party 2104 votes
