The Tongan Government is assessing its lockdown restrictions, looking at the possibility of opening some services "due to the needs of the people".
The number of Covid cases in isolation remains at four, with test results of their close contacts including a man who flew to Vava'u on work related matters due back Friday.
Hu'akavameiliku Siaosi Sovaleni says the source of the infections is still unknown, so testing has been ramped up to get a handle on the potential spread of the virus.
