A former governor of the Papua New Guinea province of Bougainville, John Momis, has been chosen as the leader of the New Bougainville Party.
The Post Courier newspaper says the party has been reorganised.
This comes as the province is about to gear up for elections in March to choose a new Autonomous Bougainville Government.
Mr Momis resigned as governor in 2005 to contest the election of the first autonomous government after the settlement of the civil war.
However, he failed in his bid to become the president, losing the contest to Joseph Kabui who died two years ago.
