The New Zealand firm that managed a volcanic island which erupted killing 22 people in 2019, has been found guilty of failing to adequately protect visitors.
47 people were on White Island - also known as Whakaari - in December 2019 when a deadly column of burning ash and steam blasted from a volcanic vent.
Most of the deceased were tourists, including 17 Australians and three Americans.
The deadly eruption also left 25 people with severe burns.
A court in Auckland on Tuesday found that Whakaari Management failed to “assess risk” to visitors sufficiently, or provide them with protective equipment.
“This was critical to ensuring that tours could be conducted safely” said Judge Evangelos Thomas.
A second charge of ensuring the safety of those working on the island was dismissed.
