The end of French Polynesia's airport firefighters strike has been put off in Tahiti amid a dispute between two unions.
Most grievances have been settled and outer island airports have resumed full services.
However, in Tahiti firefighters employed by the airport company are yet to agree to return to work.
This has affected the schedule of international flights.
The French High Commissioner Rene Bidal has expressed concern at the impasse and warned that firefighters ordered to maintain a basic service risk jail if they refuse to comply.
The five-day stoppage last week crippled domestic air travel to dozens of destinations and disrupted tourism.
