The number of confirmed Covid-19 cases in New Caledonia has risen to 10, a week after the illness was first diagnosed in two travellers.
The government has declined to give details, saying from now on the location of those testing positive will be withheld.
The new communication policy has been prompted by reports that death threats had been made.
The government says people displaying symptoms of the disease should contact their doctor and, once given instructions, visit one of the territory's four centres for testing.
Within a week, 15,000 test kits and two million masks are expected to be delivered.
Restrictions have been tightened since Monday midnight and all events are cancelled.
Anyone moving about has to carry a written attestation to justify their action.
