The Solomon Islands National Peace Council says it is about to sign up another four wards or about 200 villages to its campaign to remove weapons.
The Peace Council chairman, Paul Tovua, says this will mean about 600 villages on Guadalcanal and Malaita have committed to being weapons-free.
The communities receive rewards such as sports equipment or schools assistance for making the commitment.
And Mr Tovua says they are now planning a national peace summit in Honiara next month.
He says they are expecting all sectors of the community to take part.
"Of course, the government, the churches and the leaders, NGO's, civil society will also be part of the summit so that it could help map the way forward for peace and hopefully progress in the Solomon Islands."
