A 25-year-old French tourist spent a cold and wet night "hunkered down" in the bush near the Routeburn Track on Tuesday night.
Senior Constable Chris Blackford, of Queenstown, said the tourist failed to meet at a prearranged point after walking the Lake Sylvan Track and a search and rescue operation was later initiated.
Police, search and rescue volunteers and Department of Conservation staff were involved in the overnight search.
Southern deployment co-ordinator Senior Sergeant Craig Brown, of Dunedin, said other tourists alerted police to the Frenchman's whereabouts at 8.30am yesterday.
Other than being "cold and wet", the man was fine.
