A review is underway to determine whether Bougainville's autonomy is being properly implemented.
It is the second review since the autonomous Bougainville government, or ABG, was formed in 2005 and will also involve the Papua New Guinea government.
The ABG chief secretary, Joseph Nobetau, said the review, coming less than a year out from a planned referendum on possible independence, will look at the implementation of autonomy from both sides.
He said he and his PNG counterpart, Isaac Lupari, will look forward to a review with practical outcomes that set out the way forward for autonomy and the referendum.
The review team is supported by the United Nations at the request of both governments and will be led by Canadian parliamentarian, Kevin Deveaux.
They will meet with a wide range of people, from national and Bougainville ministers and MPs, government officials, civil society, ex-combatants, youth and women's groups.
Mr Nobetau said the review will consider four areas of autonomous authority handed to the ABG: the financial arrangements; the delivery of public service, technical and legal aspects; and good governance.
