New Zealand's Scenic Hotel group has yet to reveal why it ended links with Tonga a month ago.
The company had been running the Scenic Hotel Tonga near the country's only international airport, Fu'amotu.
Attempts by RNZ Pacific to get the company to explain its exit have been unsuccessful.
In Tonga, there has been speculation that a new law affecting foreign owned businesses may have been a factor in the withdrawal, and that a refurbished Dateline International hotel in the heart of the capital may also have had an effect.
Scenic, which manages a number of hotels in New Zealand, also runs the Matavai Resort in Niue.
