The 13 organisations and individuals charged by Worksafe in the aftermath of the eruption are due back in court today.
They are accused of health and safety breaches in the lead-up to the disaster - but the charges do not relate to events that day or the rescue efforts.
It's the biggest case ever taken by Worksafe and reporter Sarah Robson is in Whakatane for the two-day hearing.
She spoke to Philippa Tolley.
