"But we parted a while ago and they have built up a separate party and we are not together. Anything is possible though, in politics, you can't discount anything."
Labour's Meka Whaitiri said she had a clear mandate from Ikaroa-Rawhiti, despite claims by Mana on the campaign that Mr Nikora was neck and neck with her.
"The people of Ikaroa-Rawhiti have placed their faith in me and I'm happy with that.
"When you go into any battle you go in prepared and you don't take your opposition lightly and I haven't done that. I've respected the other candidates and put my best foot forward and at the end of the day the people of Ikaroa-Rawhiti have spoken."
Labour leader David Shearer said the byelection was the starting point for Labour to take back all the Maori seats and was effectively the end for the Maori Party.
"I think the Maori Party is sliding away now I really don't think it can build itself up."
Both the Mana and Maori paties have already said they will stand again in Ikaroa-Rawhiti in 2014.
Mr Nikora said he was pleased with his campaign and expected to run again.
"I'm proud of the fact that we've awakened a lot of people that weren't politically minded, who didn't think it was relevent."
He said Mana and the Maori Party needed to talk about the future.
"People in the electorate, just talking to normal grassroots people they didn't like to have to decide between Mana and Maori. They wanted us to roll together and I think that would be a beautiful thing."
Dr Sharples said the party would meet over the next few days for discussions before its annual meeting in a fortnight where its leadership issues are expected to be addressed.
Dr Sharples said other factors contributed to the result including Labour's party machinery and Nikora's high profile because of his time hosting Homa Te Pakipaki on Maori Television. However, Mr Raihania's portion of the vote was similar to the 2012 election and he had campaigned well, Dr Sharples said.
"While we are disappointed, we are proud of the way he ran his campaign. He was honest, committed and he focused on the issues that are important to the people of Ikaroa Rawhiti."
Mr Raihania was unsure whether he would stand again, but was confident of the future of the party.
For Labour, it was time to celebrate. The mood was buoyant at Whaitiri's election day headquarters at Manutuke Marae from the moment the first results came in. Her brother Robert said that Whaitiri's usual role at the marae was in the kitchen doing the dishes, but now was the time for her to step up.
Among the celebrations, there was still time to remember Parekura Horomia, whose death in April had resulted in the byelection. One woman at the marae, Lil Huata, had campaigned for him for four elections and wore a picture of Mr Horomia on her red jumper. She retired it last night.
Although Whaitiri's result was lower than Horomia's 60 per cent in 2012, she faced a stronger line up of candidates in both Nikora and the Green Party, which did not stand a candidate in that seat in 2012. The Greens' Marama Davidson secured 1,188 votes (11 per cent).
