The board is made up of three trustees appointed from the community and one each appointed by the local Member of Parliament, Lincoln University, the Mayor of Christchurch and the Christchurch Civic Trust.

Day to day management of the park is delegated to the Mount Vernon Management Committee.

The management committee meet jointly every six weeks.

The Trust Board meets as required throughout the year.
