Te Waihora / Lake Ellesmere (Sea Openings).

Lake Ellesmere/ Te Waihora Lake Opening Fund was established as part of the CPWL consent with an annual contribution towards sea openings. An internationally internationally significant wetland, boasting the most diverse bird habitat in New Zealand. With no natural opening to the sea, human intervention is required to open the lake, manage lake levels, keep the lake connected to the sea for migratory finish, and enablement of mahinga kai.
