The French government has said it will deploy troops to secure ports and the main airport in the Pacific territory of New Caledonia as unrest continues.
Clashes erupted on Monday after lawmakers in Paris backed changes to voting rolls that the indigenous population say will dilute their political influence.
At least four people, including a police officer, have been killed in the violence.
Speaking after chairing a crisis meeting, French Prime Minister Gabriel Attal said a ban on TikTok and a fresh curfew were being introduced to try to restore calm.
President Emmanuel Macron had earlier declared a state of emergency, warning that the violence would be met with a strict response.
The unrest started after lawmakers in Paris proposed granting French residents who have lived in the territory for 10 years voting rights in the province.
The changes were approved by the French parliament on Wednesday morning.
Shops have been looted and public buildings torched and hundreds of people, including around 100 police and gendarmes, have been injured, French Interior Minister Gerald Darmanin said.
"Soldiers have been deployed to secure ports and the airport in New Caledonia," Attal told a crisis ministerial meeting in Paris on Wednesday.
The representative of central government in the territory, Louis Le Franc, has "declared a curfew and banned TikTok", Attal said.
