The Trust currently has ten trustees, made up of eight appointed trustees and two advisory trustees.
Christine Stanley – advising on behalf of the rural community

The Trust receives significant support from officers in Porirua City, Greater Wellington and Wellington City Councils.
The Trust originally contained nominated members from the Greater Wellington Regional Council, the Porirua City Council and the Wellington City Council as well as a representative from Ngāti Toa Rangatira. The Councils decided that given the advocacy nature of the Harbour Trust their representatives were potentially subject to conflicts of interest. To resolve this situation it was agreed to reconstitute the Trust without council representatives.A new Trust has been approved by the Charities Commission and will come into being shortly.
