A special ceremony will today celebrate the landmark addition of Taupō Waters to the joint management agreement between Tūwharetoa Māori Trust Board and Waikato Regional Council.
The addition will see the parties work closely together over the management of Taupō Waters, which includes Lake Taupō and the tributaries flowing into and out.
Previously the joint management agreement solely addressed the upper Waikato River catchment.
The council and board said they were pleased Taupō Waters were being included in the agreement.
"This milestone is a further step toward realising tino rangatiranga and mana motuhake over our taonga tuku iho," Tūwharetoa Māori Trust Board chief executive Topia Rameka said.
