Residents and farmers hoping to address ongoing concerns over how water in the Selwyn-Waihora catchment is managed are battling on.
A public meeting with Canterbury Medical Officer of Health Alistair Humphrey and Fish and Game environmental adviser Scott Pearson on water issues will be held on Thursday.
Fifth-generation dairy farmer Alison Dewes, who is also an ecologist and veterinarian, Farmers for Positive Change leader Rick Burke and Freshwater ecologist Russell Death will also travel from the North Island to speak.
It comes after new group Selwyn Waihora Water Improvement Mission was formed last month in a bid to find a solution to water issues in the district.
Residents and farmers from around the district have collaborated together to focus on health issues in drinking water and the level of nitrate in wells.
