Our Structure

Toimata Foundation supports two nationwide programmes:

Te Aho Tū Roa

Te Aho Tū Roa national team works directly with a range of local participants including teachers and community members. Poutautoko roles are being established to provide local support to participants.


The Enviroschools national team works closely with 15 Regional Coordinators employed locally by our partner organisations. Regional Coordinators support teams of Facilitators who in turn support a group of schools and/or ECE (Early Childhood Education) centres.

The support model for these two programmes is shown in the diagram below.

Founding Partner: Te Mauri Tau

Te Mauri Tau Incorporated is an educational, environmental and health organisation based in Whaingaroa/Raglan. Te Mauri Tau works in creative ways, drawing from the wisdom and knowledge contained within traditional Māori understanding to enhance the well-being of the individual, whānau and community. The organisation was a partner in the development of the Enviroschools Programme in the late 1990s, and subsequently when The Enviroschools Foundation was formed in 2003, Te Mauri Tau became a founding organisation with a permanent member on the board.

Development by Te Mauri Tau of the Māori perspectives content in the Enviroschools Programme, as well as the development of Te Aho Tū Roa, is integral to all strands of the work of Toimata Foundation.   Te Mauri Tau operates from a site that is designed as a living and evolving model of sustainability.  From this base Te Mauri Tau provides the venue and manaaki for the events that ground participants in the kaupapa of both Te Aho Tū Roa and Enviroschools.
