New Caledonia has registered another Covid-19 case in its quarantine facilities, bringing its tally to 27.
The individual has been transferred to the dedicated isolation unit at the hospital.
There has been no community transmission in New Caledonia.
A compulsory two-week quarantine in government-sponsored accommodation is imposed on all arrivals.
The government said there were just over 500 people in such quarantine, with about half of them French officials flown in to help supervise the independence referendum on 4 October.
The border is largely closed and flights are strictly limited under a plan which will remain in force until at least 27 March.
Quarantine-free travel is possible between New Caledonia and Wallis and Futuna, which is the only French-run territory without a single Covid-19 case.
