Three more people have died of measles in Samoa over the last 24 hours, bringing the death toll to 42.
Since Thursday, 213 more cases have been reported to the Ministry of Health, it said in a statement on Friday.
A total of 3149 cases have been reported since the outbreak began.
Of the cases, 197 are currently in-patients at health facilities. Twenty of the admissions are critically ill children and three are pregnant women.
Hospitals are not designed to deal with the amount of people they are treating, Dr Scott Wilson told Newshub on Monday.
Wilson is part of the New Zealand medical assistance team working around the clock in rural Samoa to help administer vaccines.
"The minute you get hospitals running at 200 to 300 percent capacity - I think it speaks for itself. It's incredibly serious," he said.
Since the beginning of the mass vaccination campaign on November 20, more than 50,000 people have been vaccinated against measles.
The Ministry of Health admits a low turnout rate for infants and children and urges any parents who have not vaccinated their children to do so.
The disease is believed to have spread from Auckland to Samoa. Between January 1 and November 22 there have been 1678 measles cases in Auckland.
On Thursday, the Auckland Regional Public Health Service also released a statement saying that it had been notified of a passenger with measles on a flight between Samoa and Auckland on November 23.
