Tuwharetoa Settlement Trust general manager Dylan Tahau is leaving to take up a new position at Taupo District Council.
Mr Tahau is an environmental advocate and community leader having held several senior positions within the public sector and the Ngati Tuwharetoa iwi.
Chairman Rakeipoho Taiaroa said Mr Tahau left having made a significant contribution to the trust's current strong position.
"Dylan is a capable leader and has been a great support to the trust, helping us to achieve the positive operational and financial results we now experience.
"He has also facilitated our working together with others, both within Tuwharetoa and with our central North Island whanaunga iwi," he said.
"We are sad to see Dylan go, but we wish him well for his future endeavours."
Mr Tahau said he was pleased that the Tuwharetoa Settlement Trust was continuing to provide a steady, capable whare for Ngati Tuwharetoa to rely on.
"Strong foundations have now been laid and the trust is in a really good place," he said.
Mr Tahau will take up his new role as Strategic Development Manager at council next month but will remain a trustee of the trust.
