The Movement is to use the Port Vila summit to evaluate its first three years, establish by-laws, elect executive members and discuss future strategy.
Its secretary-general Octo Mote said the major Papuan representative groups which make up the Movement would be present.
"This time everybody is here, not like last time when many of them were stuck in Papua New Guinea. No, everybody is here. In terms of persons that are participating, this is very successful, from the representation."
Octo Mote said he hoped to be re-elected.
