A record crowd of at least 70,000 attended the airshow at Wānaka Airport.
The last airshow, in 2018, injected about $42 million into the region’s economy, Mr Taylor said.
"I am confident it will be $50million. This takes in a little inflation as well," he said.
Warbirds chairman John Gilks was also buoyant about the economic success of the show, but preliminary financial details were not likely to be available until May.
Wānaka Business Chamber chief executive Glenn Peat told the Otago Daily Times the only caveat was the Easter Trading restrictions on retailers in Wānaka.
"What you might find is in the future there might be an exemption put through for Wānaka like there is in Queenstown for Easter trading laws," Mr Peat said.
About 80 aircraft were on display at Wānaka Airport, with most coming from around the country or overseas.
RD Petroleum aviation manager Jack Robert said he was aware at least 70 private aircraft and several charters had brought many passengers to Wānaka.
Mr Robert estimated RD Petroleum would have pumped about 20,000 litres of aviation gas to refuel aircraft at Wānaka Airport, and about 30,000 litres of jet fuel to refuel jet planes, such as those used by the Royal NZ Air Force.
He did not know how much fuel the USAF F-16 fighters required because they had refuelled at Christchurch Airport or used an airborne tanker mid-flight.
