Prime Minister 'Akilisi Pohiva told parliament on Tuesday that he has doubts that Tonga will be ready in time to host the event.
He said the government had still not found land to build an 18-hole golf course for the Games and the scheduled upgrade of the Teufaiva Stadium was also in doubt.
But the President of the Pacific Games Council, Vidhya Lakhan, said they remain supportive of Tonga as host nation.
"As far as the Pacific Games Council is concerned, the 2019 Pacific Games will continue to be hosted by Tonga," he said.
