The health authorities in French Polynesia say they have detected the territory's first case of chikungunya.
They say the mosquito-borne disease was diagnosed in a 60-year-old woman who had recently returned from Guadeloupe in the Caribbean.
She is reportedly not in need of hospital care.
The disease has been in New Caledonia and this year, there has been a large outbreak in Tonga as well.
In 2006, the disease claimed 250 lives in the French Indian Ocean island of La Reunion where the epidemic hit about a third of the island's population.
