"The inquiry is aware of interested parties who would only want to be heard on the second topics - and input on this would be welcome at the initial hearing."
The proceedings of Thursday's hearing, which may continue to Thursday morning, were expected to start with opening comments from the panel chair, followed by identifying which submitters would want to be heard and present evidence and/or submissions.
The inquiry will also note the parties who wish to be designated as "core participants", and will release its decision on this shortly after the initial hearing, she said.
The public hearing will be held at the Hastings District Court at 10am on Thursday, October 27. The inquiry is required to report back no later than March 31 next year.
Justice Stevens will be joined on the panel by NZQA CEO and former director-general of health Dr Karen Poutasi CNZM, and local government and engineering expert Anthony Wilson.
