In just five years, Queenstown's burgeoning tourism sector has doubled the workload of Frankton-based St John Wakatipu paramedics, who this ski season attended more than 1000 people.
St John Wakatipu operations team manager Alana Reid, of Arrowtown, said the emergency service attended 1100 callouts in 2005 - just a few more than the 1067 for winter 2010.
However, Ms Reid said the 2010 ski season was a case of "business as usual - it's just what we do" for Queenstown paramedics who attended 1067 people from early June until the close of the season this month.
Of that number, 420 were incidents relating to people treated from the Remarkables and Coronet Peak ski areas.
The worst of those was an 80-year-old Japanese skier who died after collapsing at Coronet Peak in August, Ms Reid said.
Most injuries were treated within the Lakes district.
Many skiers and riders were treated for fractures.
Injuries generally came about during falls, when people put their hands out or when bindings did not release, Ms Reid said.
Average annual callouts now numbered about 2200 and Ms Reid said the "overall trend" was for callouts to increase in tandem with more tourists.
"It's an indication of just how much the district and tourism numbers have grown," she said.
St John Wakatipu covers the Wakatipu basin from Glenorchy in the north, Kingston in the south and the Cardrona Saddle and Roaring Meg to the east.
Callouts peaked in July with 192 people taken from the Remarkables and Coronet Peak - a surge Ms Reid put down to Australian, then New Zealand, school holidays that month.
In June, 38 people were directly transported by ambulance from both ski areas.
In August, the figure was 141, and by September had dropped to 49.
