The Fiji military says Friday's scheduled Commander of the Republic of Fiji Military Forces Handover Parade has been postponed, citing adverse weather.
Commodore Frank Bainimarama, who has led the armed forces for 15 years, had said he would step down at the end of this month to launch a political party.
The information ministry has given no new date.
The regime is yet to announce his successor.
Observers say among those being considered is his brother-in-law and former navy commander, Francis Kean, despite him having served a jail sentence for killing a guest at a Bainimarama family wedding in late 2006.
