The Marram Community Trust is a not-for-profit organisation governed by a Trust Deed and Board of Trustees. It is a registered charitable trust in terms of the Charitable Trusts Act 1957, but is not a registered charity in terms of the Charities Act 2005, so it does not qualify for tax exemption.


The initial funding to establish the holiday homes network came from war bond fees. When this option was depleted, funding came from regular contributions by employees of the Post Office.

Today, Marram is funded by the holiday home rentals, contributions and income from investments. The funding provides money to reimburse healthcare expenses, heavily subsidise the rental cost of the holiday homes and maintain the homes from year to year. Most years, this money is completely spent but any excess is put back into the organisation.

The Trust Board

A minimum of seven members of the Trust Board come from Affiliated Organisations, as determined by the Trust Deed. Three Trustees are nominated and appointed by the three founding Affiliated Organisations and three Trustees are nominated by our contributors. The Board may also appoint other Trustees from time-to-time to provide expertise and ensure that the Board has at least seven members. The Chairperson of the Marram Community Trust Board is always the person in charge of the HR functions of Spark New Zealand.

Through oversight, review and counsel, the Trust Board establishes and promotes Marram Community Trust’s business and organisational objectives. The Board oversees the Trust’s business affairs and integrity, works with the CEO to determine the Trust’s vision and long-term strategy, performs an annual CEO evaluation, oversees CEO succession planning, oversees internal controls over financial reporting and assesses risks and strategies for risk mitigation.
