The Tongan government has yet to reveal more details about a cyber breach of its health records that occured 10 days ago.
The breach by hackers and their subsequent demand for payment were revealed in parliament four days after the event.
A cyber expert from Australia has been in the country for nearly a week, and local media report that more personnel are being brought in.
Meanwhile, concern about illegal access to health records is mounting, amid a requirement that patients bring any medical records they have into the country's hospitals as staff are now relying on manual data.
Former Prime Minister Siaosi Sovaleni wants a full explanation from the government, but most of the country's leaders are in Ha'apai this week for the annual conference of the Wesleyan Church.
Police have said that the hackers have demanded a payment in "the millions".
A media conference scheduled for later on Thursday is expected to shed more light on the issue.
