This presentation will cover the ongoing work to restore the water quality of the Rotorua Te Arawa Lakes, particularly Lake Rotorua. The Rotorua Te Arawa Lakes Programme is a partnership between Te Arawa Lakes Trust, Rotorua Lakes Council and Bay of Plenty Regional Council and has had significant Crown and Council investment since its inception in 2005 with the signing of Te Arawa’s Treaty of Waitangi Settlement. The core role of Bay of Plenty Regional Council in this Programme is to reduce nutrient export to lakes and streams by requiring and enabling land use and land management change to ensure sustainable land use practice. This presentation will cover the success and challenges of this work, a programme of generational change.
