Outgoing chief executive Arthur Klap said while he was confident in the delivery of the 2017 event, it was satisfying to see positive numbers.
The report showed the figure was generated by domestic and international people visiting the resort solely to attend the Games.
It showed the $13,400,669 spent in Central Otago equalled 45,400 bed nights, which Mr Klap described as a record.
The international contribution was $9,378,919, with domestic visitors spending $4,021,750.It put the net national benefit at $7,225, 332 — after subtracting money that "flows back out", Klap said.
He admitted it was a complicated calculation but it was based on the average stay and how much money people spend.
No multipliers have been applied.
"This is such an outstanding result and the figures are calculated purely from those who came to New Zealand and Central Otago primarily because of the Winter Games."
Some information was gathered directly from the 865 competitors — 715 of whom were from overseas — from 42 countries.
Data also showed entries were up 67%, which is attributed to it being a pre-Winter Olympics year.
Mr Klap said the 120-strong Chinese contingent booked 4000 bed nights for the games, staying 42 days on average.
The study also showed spectators, who watched events at five skifields in the Queenstown and Wanaka areas, stayed an average of six days.
Mr Klap said the figures did not include the value of media coverage.
"By January 31, 2018 the Games will have achieved more than 1000 hours of international coverage from more than 10,000 transmissions, which is obviously of enormous value to New Zealand, particularly in terms of tourism."
The huge international coverage, through television, social and print media, that the Audi Quattro Winter Games received make the 2017 edition one of the most widely seen events ever in the history of NZ sport.
Winter Games NZ Trust Board chairman Sir Eion Edgar said the economic return highlighted its success.
"This is a fitting tribute to Arthur Klap, who is standing down as chief executive of Winter Games NZ. His inspired leadership during the past 10 years has ensured the event has continued to grow in importance both locally, throughout New Zealand and internationally, so that it is now recognised as the third most important winter multi-snowsports event in the world after the Winter Olympics and the X Games."
Last month Mountain Scene reported the Games, currently held every two years, may be held annually from next year.
