The death toll rose to 20 on Thursday from a volcanic eruption on New Zealand's White Island last month, as two people still missing were officially confirmed dead.
The two individuals were Hayden Marshall-Inman of
New Zealand and Winona Langford of Australia,
police said.
"The chief coroner has ruled that both Winona and Hayden died on White Island," John Tims, a deputy police commissioner, said in a statement.
