The writs for the second elections in the autonomous Papua New Guinea province of Bougainville are to be issued tomorrow and nominations then open for a seven day period.
Voting is due to start on May the 7th and run for two weeks with the results announced in early June.
The elections for the 41 assembly seats and a president were first held in 2005 and resulted in a resounding win for a former rebel leader, Joseph Kabui.
Mr Kabui died in office two years later and was replaced by James Tanis.
A former Bougainville governor, John Momis, who ran second to Mr Kabui in 2005, is one of those planning to contest the presidency.
