Two major Te Arawa tribal entities are undergoing changes to senior management roles.
The tribe's post Treaty settlement trust, Te Pumautanga o Te Arawa, and its commercial body, Te Arawa Group Holdings Ltd, are being transformed.
Te Pumautanga chair Eru George confirmed on Tuesday he has been ousted from the position.
A spokesperson for the organisation says he will be replaced by Alan Skipwith of the Tuhourangi Tribal Authority.
The spokesperson says Mr George was voted out at a recent bi-monthly board meeting.
Adding to the changes, the organisation's general manager, Nero Panapa, finished last Friday, after handing in his resignation well over a month ago.
Meanwhile, the organisation's commercial arm, Te Arawa Group Holdings Limited, is advertising the role of chief executive.
It was previously held by Roger Pikia, who stepped down earlier in the year after a High Court ruling in March over a family matter he was involved in.
The two-day hearing examined an allegation that he transferred land belonging to his late grandmother into his ownership without her knowledge.
He was her power of attorney at the time.
