Who are the Supporters?

The Supporters of Tiritiri Matangi Inc. is a non-profit conservation volunteer group founded in 1988 to further the aims of the Tiritiri Matangi habitat restoration and species translocation project. Since then we have grown into a major conservation group with over 1600 members and work in partnership with the Department of Conservation to co-manage the project.

Our mission


Our vision is to help create the ultimate wildlife sanctuary and healthy ecosystem, a magical place that engages and inspires volunteers, visitors and other New Zealanders to understand our unique heritage and make a difference in their own environment. We have four key objectives:

Conservation: Tiritiri Matangi has a healthy functioning ecosystem that is representative of the pre-human Hauraki Gulf area in which the island is located
Insight: Tiritiri Matangi is a key centre for biodiversity research and management
Inspiration: Every visitor is inspired to become an advocate for New Zealand’s unique biodiversity by making a difference in their own community
Participation: We provide a range of opportunities for people to participate in the Tiritiri Matangi story, as volunteers or as visitors

Our achievements


In the past 22 years we have:

  • Funded a number of translocations (transfers) and top-ups of rare species, including kokako, rifleman and Duvaucel’s geckos
  • Funded a range of interpretative signs
  • Built a new visitors’ centre, with state-of-the-art interpretation
  • Built an extensive vehicle and equipment storage facility
  • Purchased various vehicles including the island’s tractor, ute and trailer
  • Funded annual weed management programmes
  • Funded ongoing scientific research
  • Developed an extensive guided walk programme, with over 200 guides
  • Built and run a shop on the island, entirely manned by our volunteers, with all proceeds invested in the project.

The Supporters has a constitution and an active committee.

Memorandum of Understanding


On 7 November 2004 at the head office of the Department of Conservation offices in Auckland, a significant event took place with the signing of a Memorandum of Understanding (MoU) between the Supporters of Tiritiri Matangi and the Department of Conservation.

A Memorandum of Understanding is a legal document outlining an agreement between parties making clear the objectives and recognizing the different roles of each party. In the case of the Supporters, the document outlines our aims and responsibilities on Tiritiri Matangi and outlines a mutual cooperation and consultation with the Department on many aspects such as work programs, health and safety and concessions. The document protects the interests of both the Supporters and DoC and ensures the island receives the benefit of this partnership in the future.
