National leader Judith Collins says she would launch a Royal Commission of inquiry into the Whakaari/ White Island disaster which killed 21 people from four countries.
"I think it deserves it - it is a huge loss of people and huge injuries to others whose lives were saved. I think there should be one into it. I think it's something that New Zealanders would want to see," Collins said.
There were 47 people on the Bay of Plenty volcano on December 9 when it erupted. Of those, 21 people died.
Dozens more suffered life-changing injuries, many spending months in hospital and needing surgery and skin grafts for their horrific burns.
