Changes have already been made to adventure tourism safety as the Whakaari White Island trial ends.
The island's owner, Whakaari Management Limited, has been found guilty on one health and safety charge brought by WorkSafe.
It failed to ensure adequate risk assessments ahead of the 2019 tragedy that killed 22 people.
Former Tourism Industry Aotearoa CEO Chris Roberts told Kate Hawkesby that there was concern that WorkSafe was the prosecutor.
He says it was clear there were failings in WorkSafe's oversight, but they weren't prosecuted, they were the prosecutor.
