France is on tenterhooks ahead of legislative elections which could see the far right take the largest number of seats in parliament.
The first round takes place on Sunday, followed by a second round on 7 July.
The High Commission, which represents the French state in the archipelago, announced a ban on gatherings from Saturday morning until Sunday evening in New Caledonia, which was hit by the deadly unrest last month.
“In order to pursue security efforts… gatherings will be prohibited from 6:00 am Saturday June 29 (1900 GMT Friday) to 8:00 pm Sunday June 30,” the High Commission said in a statement.
In mid-May, rioting and looting erupted in New Caledonia over an electoral reform plan that Indigenous Kanak people feared would leave them in a permanent minority, putting independence hopes definitively out of reach.
The High Commission also said that the 8:00 pm to 6:00 am curfew in place since the start of the riots had been extended until 8 July.
High Commissioner Louis Le Franc noted that the situation “had improved”, but pointed out that public infrastructure had recently sustained “very serious damage.”
In recent days French authorities had insisted that Noumea, the capital of New Caledonia, which is located nearly 17,000 kilometres from Paris, was back under their control.
But a fresh bout of violence erupted on Monday after seven independence activists accused of orchestrating the deadly riots were sent to mainland France for pre-trial detention.
The High Commission denounced “assaults on firefighters carried out by rioters” in recent days.
The authority also condemned “in the strongest possible terms” a fire that broke out on Thursday night at the construction site of the La Tontouta first response centre close to the international airport.
More than 1,500 people have been arrested since the unrest began in New Caledonia.
The violence has left nine dead and damage estimated at more than 1.5 billion euros ($1.6 billion).
