Tuwharetoa Settlement Trust says it needs to do more work before it can investigate investment losses and overspending.
It called off a special general meeting over the weekend because it has not yet engaged kanohi ki te kanohi (face-to-face) with the parties identified in the review.
The trust said it had meant to hold those talks before publicly announcing the investigation through panui (newsletter).
The chairman, Dylan Tahau, said feedback suggests last month's panui created a perception of impending legal action against some of their own.
He has apologised to its people, telling them the hui will now be held on 20 December as part of the annual general meeting.
The trust said the financial losses were not of a malicious nature, but more as a result of the trust not having a broad enough range of skills and experience in both governance and management.
