Trelissick Park Group logo


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. Groups involved in this restoration include the Highland Park Progressive Association, Ngaio Crofton Downs Residents’ Association, Royal Forest and Bird Protection Society, Wellington Botanical Society and the Wadestown Residents’ Association.

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. The Greater Wellington Regional Council also provide support with pest control.

The projects undertaken by the Trelissick Park Group work towards the Group's Five Year Plan (March 2019 update) and a key means of implementing the Group's plan revolves around the scheduled working bees.

Adopt a Spot Scheme

This scheme is designed to encourage people to adopt their own spot within the park to look after. This can be done at any time convenient to them rather than having to work in with a working bee schedule. You can choose both the size and location of your spot.

See Adopt a Spot locations (2015 update) for locations of some current and future Adopt-a-Spots! Hover your cursor over spots for more detailed information (may be browser dependent).

The adopt-a-spot coordinator can be contacted via email address
