More than 500 people including police officers, church ministers and representative rugby players have been arrested for breaching the quarantine, lockdown and curfew restrictions.
Twenty-four people were also detained for holding gatherings of more than 20.
Prime Minister Frank Bainimarama warned anyone caught breaking the law would be dealt with severely.
"This level of lawlessness is irresponsible, un-Fijian and just plain stupid," he said.
