Vatemo Ravouvou and two other men were alleged to have left their quarantined rooms to drink kava and alcohol last week.
The trio were granted $US470 bail bonds and three sureties.
The matter was adjourned to 27 October.
Meanwhile, the military said a soldier working at a border quarantine facility had also breached the rules.
Army Commander Rear-Admiral Viliame Naupoto said the officer came into contact with those in the quarantine facility.
Naupoto said the soldier will be "dealt with severely" when he completes his 14-day isolation period.
