Waikato Regional Council chief executive Vaughan Payne said the natural resources under the umbrella of Taupō Waters would benefit from the new co-management arrangement.
"We have seen the value of the inter-generational vision that Ngāti Tūwharetoa brings to the council's decision making, including their extensive experience and knowledge of freshwater resources, which are some of our region's most significant taonga."
The small ceremony by the joint management agreement committee is being held at Waikato Regional Council chambers at 11.45am.
The agreement sets out how the council and the trust board will work together when carrying out specific legislative duties and functions, including exercising powers under the Resource Management Act.
Waikato Regional Council and Tūwharetoa Māori Trust Board have also agreed to develop a framework over the next 18 months. This framework will consider transfer of duties, functions and powers pursuant to section 33 of the Resource Management Act.
