French Polynesia has recorded another 12 Covid-19 cases, rasing the tally for August to 465.
The territory has seen a double-digit increase of infections every day for the past three weeks and the wearing of masks has now become compulsory in crowded places.
Social distancing is also being encouraged, but unlike after the first Covid-19 outbreak in March a general lockdown has been ruled out by the government.
Several unions have warned they would call a general strike on Thursday if the government refuses to improve protection and re-introduce a two-week quarantine for arriving travellers.
The quarantine requirement was abandoned in the middle of July when flights restarted to revive international tourism.
Meanwhile, the health minister said the territory, which was again on maximum alert, could see targeted restrictions affecting some neighbourhoods.
Since the start of last month, four airlines have resumed flying between Tahiti and both France and the US.
