The Papua New Guinea cabinet is to meet in the Bougainville town of Buka on Wednesday.
The historic event, postponed last month, comes just 10 weeks before the referendum on independence from PNG.
The Prime Minister James Marape will also address the Bougainville parliament, following a similar presentation to the national parliament by Bougainville President John Momis last month.
The Post Courier newspaper reports the agenda for the meeting will focus on Bougainville infrastructure projects and other Bougainville matters.
Mr Marape is also to launch a solar farm project at Wakanai before travelling to Buin in the south for a meeting on Friday of the Joint Supervisory Board, the agency that oversees the Bougainville peace process.
