The acting secretary general of the Pacific Islands Development Forum, Feleti Te'o, says the agency will fill a void that exists among regional bodies.
The Fiji regime leader inaugurated the secretariat of the PIDF in Suva last weekend.
Rear Admiral Frank Bainimarama says he wants the body to become the pre-eminent regional agency in the Pacific, saying ordinary Pacific Islanders are no longer served adequately by the Pacific Islands Forum, which is also based in Suva.
But Mr Te'o, who until recently was one of two deputy secretary generals at the Forum, says the new agency will not be competing with his old colleagues.
"It took me a while to agree to take on this short-term assignment and the clear instruction and brief that I was provided is that this organisation would not in any way compete, or seek, to take over or to compete with any other regional organisations including the Pacific Islands Forum."
