Reports from French Polynesia say the French high commission will not tolerate any attempts by construction workers to block access to Papeete's new hospital.
Several companies claim they are still owed money but they have failed to secure a meeting with the territory's government to discuss their grievances.
According to Tahitipresse, only a French high commission official was available for the company bosses to express their concerns.
Speaking on local television, a government minister, Teraii Alpha, dismissed their claims, saying the bills were paid.
The Taaone hospital, which is expected to employ about 1650 staff, was blessed last weekend and has begun receiving patients this week.
The health minister, Jules Ienfa, has hailed it as a showcase of French technology which may be of benefit to Tahiti's Pacific neighbours.
