The Friends of St Mary of the Angels Charitable Trust, is an independent organisation with its own constitution and separate from the St Mary of the Angels Parish.

It is registered with the New Zealand Charities Commission and the Ministry of Economic Development. Its primary role is to supply funding or act as a principal fund raiser for the preservation and maintenance of the iconic New Zealand Historic Places Trust category one St Mary of the Angels Church, its unique organ and stained glass windows. As well it it also contributes to funds required for the lawns and gardens surrounding the Church and such other projects as defined in its constitution.

The Trust’s funding, in a regular sense, comes primarily from individuals and families giving donations and bequests. For major projects, which require substantial funding, the Trust also approaches organisations, foundations and other trusts for financial support. It is only through the generosity of individuals, families and other interested organisations that the Trust contributes to the on-going restoration and maintenance of the historic St Mary of the Angels Church and other projects which, from time to time, are deemed to be appropriate by the trustees.
