Figures released in New Caledonia show 39 police officers were injured in the first half of this year, most them while making arrests.
The French High Commissioner Thierry Lataste said this marked an increase over the same period last year, and only leaves French Guiana with a higher injury rate.
The police commander said so far this year no police officer suffered gun shot wounds, but he said a gunman fired from a car while being pursued by police and hit their vehicle's radiator.
Another officer was hit in the head with a rock while his unit tried to assist a man suffering a heart attack.
The commander Alain Martinez said there were also 47 incidents of violence against police without causing injury.
