The Ōtaki and Porirua Trusts Board is a registered charitable non-profitable organisation created under a Private Act – The Ōtaki and Porirua Trusts Act 1943. The Board has ten members who are appointed by the Governor General; 5 of whom represent the Diocesan Trusts Board, 4 representing the Raukawa Marae Trustees, and one representing the Ministry of Education.
The Boards current core business is land based asset management (including Dairy Farming, Land Rental and Rental Properties). The income generated from the land based asset management activities is applied to its Scholarship Funds, making available scholarships for Post Primary Education to members up to the age of 20 who whakapapa to one of the three Iwi of Te Ātiawa ki Whakarongotai, Ngāti Raukawa ki te Tonga and Ngāti Toa Rangatira.
The Ōtaki and Porirua Trusts Board Act, 1943 replaced the Ōtaki and Porirua Empowering Act, 1907. There have been three amendments to the original 1943 Act, in 1946, 1969 and again in 1977. Further references to the Ōtaki and Porirua Trusts Board are made in the Māori Purposes Act 1951 No 75, Part 38 and the Māori Purposes Act 1978 No 78, Part 10.
