More than 20 Australians including a recently married couple and a family of four are still listed as missing on a Red Cross list after the deadly eruption on Whakaari/White Island.

Five people are confirmed dead and eight more are missing, presumed dead after yesterday's eruption.

Prime Minister Jacinda Ardern said those feared dead were from New Zealand, Australia, Britain, the United States, China and Malaysia.

Police say there are no further signs of life on the island, following flyovers late on Monday.

Among the Australians listed are North Sydney family-of-four, Anthony, 51, and Kristine Langford, and their two teenage children Jesse, 19, and Winona, 17, the Daily Mail reports.

"We have been in touch with the embassy and the cruiseline and she is NOT missing and was not on the island when it erupted," he wrote.

"We assume she along with 4000 others on the cruise are trying to contact relatives and our thoughts are with the missing and their families."

The site also lists a 12-year-old boy from Western Australia and a 7-year-old, the youngest person missing.

Prime Minister Scott Morrison warned that Australians needed to "prepare for some difficult news in the days ahead".

In a statement released early on Tuesday, police said there are "no signs of life" on White Island and they believe anyone who could have been taken from the island alive was rescued at the time of Monday's evacuation.

"The police Eagle helicopter, rescue helicopter, and NZDF aircraft have undertaken a number of aerial reconnaissance flights over the island since the eruption," police said in a statement early Tuesday.

"No signs of life have been seen at any point.

"Police believe that anyone who could have been taken from the island alive was rescued at the time of the evacuation.

"Based on the information we have, we do not believe there are any survivors on the island."
