More than 100 people have contracted the mosquito-borne disease since the beginning of November.
Most infections have been recorded in the Noumea area, where about 20 people a week are getting infected.
The spread of the disease is attributed to the hot and humid weather.
As a result, people are being asked to eliminate mosquito breeding sites and to use repellents.
The last such epidemic in New Caledonia was declared in February.
