Mystery surrounds a visitor from Hong Kong who died after collapsing in bush on a walking track near the historic Arrowtown Chinese Settlement.
Police have established the man was 51-year-old Wai Ming Lai, a Hong Kong national who arrived in New Zealand from his home country on July 27.
However, most other details about the visitor remain a mystery, including his movements around New Zealand and in Queenstown.
About 9.30am on Saturday police received reports a man had been found unconscious in Sawpit Gully near the Chinese Settlement.
Attempts to resuscitate him by police and ambulance staff were unsuccessful.
