The agreement will be signed on Monday in Whangarei by former Mana Party and Internet Mana leader Hone Harawira, Māori Party co-leaders Te Ururoa Flavell and Marama Fox and president Tukoroirangi Morgan. Mr. Morgan has been working on the deal since he came into the role last year with a pledge to end the enmity between Harawira and his former party, and take back all seven Māori seats.
Harawira left the Māori Party in 2011 after he wrote an article questioning the party's direction alongside National. He was suspended from the Māori Party's caucus, and left soon after.
The parties went on to Ratana Pā last month, and also put up a joint team against Labour in an exhibition race at the waka ama nationals at Karapiro in January.
