As an integrated school, the school property and buildings are owned and maintained by the proprietors, the Maranatha Foundation Board.

Like other schools throughout New Zealand, Maranatha is managed by a Board of Trustees, consisting of parent elected members, as well as members appointed by the Foundation Board.

The school also has an active Parent Teacher Association, which is involved in organising fundraising activities and school social events.

The school operates on a combination of Ministry of Education funding and school fees, providing affordable, quality Christian education.
