Authorities face a difficult decision about when to begin recovering bodies from Whakaari / White Island.
Another victim has died in hospital overnight, bringing the total death toll to six.
Eight others are missing, presumed dead, while another 30 are in hospitals around the country, many with critical injuries.
Newstalk ZB's Daniel Walker told Kate Hawkesby the volcano remains extremely unpredictable, and a similar eruption could still happen at any time.
Walker says first responders in Whakatane and hospitals around the country are helping people with extensive burns.
"Some of the firefighters have seen burns before, but they have said this is like nothing they have seen before."
