A French police officer in New Caledonia has tested positive for Covid-19 - the second case recorded in the past week.
The officer, who was part of a squad flown in from France on 19 May, was transferred to the isolation unit at the hospital.
The government said the squad had tested negative before leaving France and had been held in isolation at the barracks.
It said the Covid-positive person would remain in hospital until there were two negative tests within a 48-hour period.
It also said the officer who had shared a room with the infected person was being isolated.
All arrivals in New Caledonia have to isolate for two weeks in designated accommodation and then self-isolate for another week.
The three-week confinement policy was introduced after demands by the pro-independence Kanaks and is the strictest in any French-run territory.
New Caledonia has recorded 20 Covid-19 cases which were all imported.
The border remains closed except for repatriation flights for stranded residents and for some French personnel.
New Caledonia's international airline is not expected to resume services before August.
