Trelissick Park Group

About us

Within Wellington City, a large expanse of hillside, valley, stream and parkland that encompasses Trelissick Park and Ngaio Gorge is being restored by community volunteers to create a beautiful wilderness area.

Wellington City Council provides support with pest control, supply of native plants, track and bridge work, erecting signage and information boards and stream bank strengthening. Greater Wellington also provide support with pest control.

The Trelissick Park Group has been active for more than 35 years – and has been actively supporting the predator control efforts during this period.

Ongoing bait station servicing was taken over by TPG volunteers in 2008 and has been carried out in partnership with the City and the Regional Councils. Generally the bait stations are visited monthly for replenishment as necessary. Mustelid traps (DOC200) were also introduced into the park in 2008 and are also checked monthly by volunteers for victims and/or resetting as needed. We also use A24 self setting traps. The predator control efforts are best described on our website here.

In addition to the volunteer efforts on predator control, there are about 20 organised work bees throughout the year for the Trelissick Park Group volunteers – as well as school and corporate and other groups who volunteer their efforts. Our Facebook page documents most of these endeavours as they happen.

New volunteers are welcome! Contact us using the email above, or visit our website.
