Fiji's interim prime Minister Frank Bainimarama says he has the backing of a several Pacific Island leaders, despite a rift with Vanuatu over his leadership of the Melanesian Spearhead Group.

Commodore Bainimarama just hosted a two-day meeting to reassure his Pacific neighbours there will be elections in Fiji in 2014.

Commodore Bainimarama says his "Engaging with the Pacific" meeting has been a success, despite only three prime ministers from the region attending.

He says it was all about telling the world he is reforming Fiji's electoral system.

"Nothing is going to change the way we do things in Fiji. We have a roadmap to work towards elections in 2014," he said.

Papua New Guinea's prime minister Sir Michael Somare says he thinks Commodore Bainimarama is doing a good job.

Sir Michael says it is not the Melanesian way to criticise Fiji like Australia has done.

"He's running the country, the country is surviving. He's looking at the economic base, how can he sustain the development of Fiji. The tourist industry is booming," he said.

Solomon Islands prime minister Dr Derek Sekua has also given his support to Commodore Bainimarama.
