Katie Silcock, who is the general manager of the Scenic Hotel, which is near the country's international airport on Tongatapu, said many people in a village near the hotel were in desperate straits.
She said she, and the hotel's assistant manager, visited nearby Fua'amotu village on Tuesday and found people still short of shelter, food and water.
Ms Silcock said she was also concerned at the unsanitary conditions and the risk of dengue.
