The President of Bougainville, John Momis, says he will want answers from the Papua New Guinea Prime Minister Peter O'Neill when they meet next month.
The Joint Supervisory Body, set up to help with the implementation of the Bougainville Peace Agreement, has had a series of meetings deferred by the national government, but it is set to meet on December 14th.
A critical issue for Bougainville remains Port Moresby's failure to meet its obligations to properly fund the autonomous region.
Mr Momis says the national government owes Bougainville more than $US276 million dollars in Restoration Development Grants and another $US61 million from the Special Intervention Fund.
Port Moresby challenges the figures but Mr Momis told Don Wiseman the national government does accept it owes $US110 million.
