International observers are expected to monitor the presidential by-election in the Papua New Guinea province of Bougainville which follows last June's death of Joseph Kabui - the first president elected under the province's autonomy statute.
The Post Courier newspaper reports that the observers are being invited by the PNG government.
The Bougainville National parliamentary secretary, Fidelis Semoso, says observers will help ensure the by-election is free and fair, and also help build confidence.
Mr Semoso says it is vital that people are properly informed and encouraged to keep building peace.
Meanwhile, there is concern that no budget has been prepared to provide security for next month's polls.
