New Zealand police on Tuesday called off the search for the last two people still missing following the White Island volcanic eruption earlier this month.

"The search for the two missing victims of the Whakaari/White Island eruption has been suspended," police superintendent Andy McGregor said in a statement.

McGregor added that they would renew their search "if new information comes to light" and that "the families of the two missing people have been informed of this decision."

Those that have not been found and are presumed dead are Winona Langford, a 17-year-old Australian tourist, and Hayden Marshall-Inman, a 40-year-old tour guide from New Zealand.

Another victim dies in hospital

The number of deaths from the eruption rose to 19 on Monday as another person died at a hospital in Auckland.

There were 47 people visiting the tourist destination when the volcano erupted, initially killing 13 and leaving dozens more hospitalized with serious burns. Many remain in critical condition.
