Australia is yet to confirm a date for its proposed meeting next month with Pacific leaders on regional agencies.
The top-level meeting to review the regional architecture was agreed by Australia and Fiji in October following Suva's refusal to rejoin the Pacific Islands Forum unless there are changes to the Forum's make-up.
Australia's Department of Foreign Affairs and Trade says Canberra will consult closely with the region on the concept but was not able to offer any more details.
Fiji's Foreign Minister Ratu Inoke Kubuabola said last week he was looking forward to the meeting in Sydney next month.
A New Zealand foreign affairs official says no invitation to the meeting has been received and Wellington is waiting to find out when it will be held.
