Striking employees at French Polynesia's main hospital have blocked access for all vehicles except ambulances.
This comes on the second day of a stoppage at Tahiti's Taaone hospital where hundreds of staff want to have better contracts.
A union leader says the blockade was set up because the government failed to respond to last week's strike notice.
Nearly 400 employees on limited contracts want to be given permanent status as many of them have been in their respective jobs for years.
Under French law, it is usual that limited contracts last no longer than 18 months.
The strike also coincides with the territory's first kidney transplant planned for this week.
French Polynesia's patients have been seeking operations overseas as hundreds of people are on dialysis.
