The group travelled from the United States to Fiji to return to the kingdom.
However, travel restrictions imposed as a result of the outbreak of the Delta variant of COVID-19 in Fiji meant the group cannot travel onwards to Tonga.
Tonga’s Chief Medical Officer Dr Reynold 'Ofanoa said there had been discussions to fly the passengers to New Zealand and then to Tonga.
However, that arrangement is now on hold as New Zealand battles with an outbreak of the Delta variant of COVID-19.
