This year's Pacific Islands Forum leaders' summit is being delayed to ensure greater participation by the member countries.
It is now scheduled to be held in the Papua New Guinea capital, Port Moresby, from October 25th to 27th.
Earlier this year, the PNG Prime Minister, Sir Michael Somare, indicated they planned to hold it in late August.
But an official in Sir Michael's office says it has been moved amid concerns that some members could not make an August meeting.
The official declined to say which countries wanted a delay, however an August summit could have clashed with general elections in New Zealand.
This year's Forum summit is expected to endorse the Pacific Plan, which is aimed at fostering co-operation and integration in the region.
