Prime Minister Jacinda Ardern was late to her regular Monday post cabinet press conference as she was seeking advice on what was happening at White Island.
"Police search and rescue are supporting the emergency management crews," she says.
"At this stage, we believe 100 people were on or around the island.
"Some of these people are unaccounted for.
"This is evolving at this stage ... obviously it does appear to be a very significant issue.
"They're undertaking an operation as we speak. We believe there were around 100 people ... That is my understanding [that they are tourists]."
Jacinda was not aware of any fatalities at this stage.
A joint press conference will be at 5.30 between emergency management and police, she says.
