The new cases are Samoa's largest group on one flight since the start of the pandemic.
Naseri said all of the passengers who tested positive since arriving in Samoa have been put into isolation and all are asymptomatic.
Naseri said test samples will be sent to New Zealand on the first available flight to determine which variant of Covid-19 they are dealing with.
But he said given the situation in Australia they suspect it is the Omicron variant.
Meanwhile, the chairman of the National Emergency Operation Centre, Agafili Shem Leo, has urged those who have tested positive not to panic and to heed all conditions of their isolation.
He said they are hoping there has been no community transmission but they are prepared to quickly move up alert levels if need be.
He also announced that a planned repatriation flight from New Zealand due to depart on Saturday will now be postponed until further notice.
