Discussions had started in 1964. Fund-raising was started in the form of Housie; initially in private homes, and later in Silverstream Hall; in 1967 it was decided that two-thirds of takings should go into the marae fund, and one-third to the organizing groups; the Rimutaka Maori Committee and the Mawai Hakona Cultural Group.
Doctor Humphrey Rainey was approached in 1969 to assist in raising funds for a marae, and suggested the group get professional help. As a result, he wound up as chairman of the committee, according to a June 1984 article describing the reasons for his being awarded an OBE for services to the Maori community.

An October-November Queen Carnival for a Community Centre was a major fund-raiser; the parade of 9 queens and 27 babies, all supported by businesses, started at Whakatiki Street, and passed along Main Street to King Street and then from Queen Street back to Main Street.
