New Caledonia's public broadcaster says a strike at the SLN nickel plant has been settled.
Seventy of one union's 120 members had been on strike since last Monday, forcing SLN to lower the output of its furnaces.
The union was demanding the retention of six workers who were being sacked for serious misbehaviour.
Details of the agreement to end the dispute have not been released.
SLN has been run at a loss for the past five years amid a global slump of the nickel price, with the deficit last year alone amounting to $US160 million.
Last year, the French state provided a $US230 million loan to supplement an advance by SLN's parent company Eramet of $US370 million.
