Whakaari Management Limited has been found guilty of health and safety failings ahead of the island's 2019 eruption.
47 people were on Whakaari- 22 died and dozens were seriously injured.
Newstalk ZB's Chelsea Daniels says the company was found guilty of one charge, but not the other under the Health and Safety Work Act.
"What I took away from the verdict was that WML (Whakaari Management Limited) didn't ensure adequate risk assessments were done relating to those tours happening on the island."
