A coroner's ruling concerning the death of a man in a Rotorua boiling thermal pool has been released

Matthew Tuimaualuga had been drinking and smoking cannabis with two others around the pool, when he slipped and fell in.

His death at the secluded and fenced-off hot pool behind Rydges Hotel in Whakarewarewa nearly a year ago, has been confirmed as an accident.

The mysterious case of Tuimaualuga's disappearance made headlines last year.

Police and other emergency services had difficulty determining whether a body was in the hot pool, given the extreme heat of the water and the dangerous geothermal surroundings.
