An Auckland man who helped rescue a "totally unprepared" German tourist who had slipped down Mount Ruapehu says the young man probably would have died had they not reached him when they did.
Scott Lowry was heading with his daughter Brya to the summit and stopped for a drink near the Knoll Ridge Cafe on Sunday when they heard Wanja Drees' cries for help.
"We weren't too sure if it was a couple of people yelling to each other," said Mr Lowry.
"I think the fourth time the yelling occurred Brya heard an SOS. I didn't actually see him at first but we saw him about 300 metres above the turnstile at the top of the Valley T-bar."
"He still had to traverse 300 metres across where the snow ran out to the Knoll ridge cafe but he wouldn't have got across. We had trouble walking across there."
