The Maori Party and the Mana Party are about to sign an agreement that's expected to involve electorate deals designed to enhance their chances of winning seats.
Neither party will talk about the agreement ahead of the signing today in Whangarei.
Peace moves between the two parties have been going on since July last year when Maori Party president Tukoroirangi Morgan approached Mana's leader Hone Harawira.
At the time, Maori Party co-leaders Te Ururoa Flavell and Marama Fox ruled out an alliance but said they were "open to a more cohesive relationship".
Labour holds six of the Maori seats and Mr Flavell holds the seventh.
