The torrent which swept six Auckland school students and a teacher to their deaths yesterday was powerful enough to have carried two of the bodies 2.5km down the Mangatepopo River.
Search and rescue teams from three police districts, along with volunteers and partner agencies leapt into action when a group canyoning in the National Park stream were caught out by a flash flood, but never had a chance of saving those who died.
Senior Constable Barry Shepherd, of the Taupo police search and rescue team, said four of the dead were already being extracted from the stream about the time police were first alerted to the incident.
The students, teacher and guide entered the river mid-afternoon near the Sir Edmund Hillary Outdoor Pursuit Centre base, off State Highway 47 near Turangi, and were in a vulnerable spot with steep banks on either side when the water level suddenly rose.
Mr Shepherd said the four bodies were plucked from the water not far from where the group first got into trouble.
