The New Caledonian government says it has confirmation of a first case of a zika virus infection contracted in the territory.
It says tests by the Pasteur Institute show that a 76-year-old man in Dumbea has been infected.
His infection is the 27th registered so far, with the other 26 victims having contracted the mosquito-borne disease in French Polynesia where tens of thousands of people are suffering from the disease.
There have been fresh appeals to the public to use insect repellent and to destroy possible breeding sites for the mosquitoes.
