TOSSI works in partnership with the Auckland Council to maximise the success of the Tāwharanui Open Sanctuary.

Our major projects are:

Revegetation and restoration of coastal forest and wetlands. TOSSI grows and plants up to 20,000 trees, shrubs and other plants each year to revegetate key areas of the Park.

Preserving the largely pest-free status of Tāwharanui through assisting Auckland Council with pest trapping and baiting, surveillance, maintaining the pest-proof fence, monitoring programs and observing sensitive wildlife.

Assisting with the reintroduction of native species to the sanctuary and monitoring their survival and breeding.

Monitoring NZ dotterel and variable oystercatcher during the breeding season.

Education and advocacy in schools, the local community and the media.
