RNZ reports the group was set up by the Solomon Islands Prime Minister Manasseh Sogavare, in response to the Melanesian Spearhead Group's inclusion of Indonesia as an observer and not granting West Papua membership of the group.
A number of Pacific heads of government have raised their concerns over West Papua at the United Nations, with the Tongan PM, 'Akilisi Pohiva last year asking the UN to intervene.
At a meeting in Honolulu last week, the Prime Minister of Tuvalu, Enele Sopoaga, and Nauru's ambassador to the Pacific nations, Marlene Moses joined the group.
