The Weapons Disposal Committee on Papua New Guinea's Bougainville Island has admitted that it is concerned about the high number of arms in the Kieta District.
The Post Courier reports there are still hundreds of guns in the Central Bougainville district despite an earlier assessment that 71 percent of weapons had been contained there.
This comes after a deadline to have all weapons handed in for storage by the end of last December.
The Peace Co-ordinator, Peter Sohia, says most districts in South Bougainville and Buka have 100 percent weapons containment and that one Central district has had 95 percent containment.
Mr Sohia says weapons containment in Kieta is slowly improving.
