About Us

The Lower Waiau Catchment Group was formed in December 2020. The group brings together local farmers, landowners, and community members to work collaboratively on improving land and water health across the catchment. By sharing knowledge, trialling new ideas, and supporting practical projects, the group aims to deliver both environmental and farm business benefits for the community.

Catchment Area

The Lower Waiau Catchment lies at the bottom of the Waiau River system, on the eastern edge of Fiordland. The Waiau flows down to the sea, through Tuatapere, at Te Waewae Bay. The catchment plays a key role in Southland’s agricultural production while also being home to important ecological areas, waterways, and rural communities.

Recent Events

Community meetings to discuss local land and water challenges and opportunities.
Field days exploring soil mapping, land use, and environmental management.

Projects

The Lower Waiau Catchment Group has run a range of projects and community events to build knowledge, connection, and momentum:

Habitat Assessments: Members carried out Rapid Habitat Assessments on local streams, guided by Environment Southland’s Land Sustainability Team. These hands-on sessions highlighted stream health, freshwater critters, and opportunities for improvement, finishing with good food and community catch-ups.
eDNA Sampling: Water samples from the Lilburn and Merton Streams were tested, revealing an exciting range of species including lamprey (Kanakana) and the rare Gollum Galaxid.
Knowledge Sharing: Guest speakers from other catchment groups and DairyNZ provided insights on water quality, results interpretation, and lessons learned.
Mobile Wintering Structure Project: The group developed and sought funding for an innovative mobile shelter to improve winter grazing management, animal welfare, and environmental outcomes.
Community Events: Regular BBQs, swims, and family days have kept the group connected, while providing opportunities to share knowledge and celebrate progress together.
