Questions have been raised over the appointment of a new trustee to the Crown Forestry Rental Trust.
The trust is a body which helps to fund Treaty of Waitangi hearings into state-owned forestry land.
An agreement is in place between the Maori Council and the Federation of Maori Authorities to appoint trustees.
However, concerns have been raised over the recent process for appointing Neville Baker, who is the chair of the Port Nicholson Block Settlement Trust.
A procedural hearing has been held at the High Court in Wellington and further hearings on the matter will be held in early March.
