Details of the attractions and ticket prices will be announced on October 1.
But Mr Newport, who has corporate backing for the Ardmore event at Ardmore, has been turned down by Auckland Council's events body after asking it for money to fund a free public event over the waterfront on the Saturday and Sunday of the Anniversary Weekend.
He said a free air show over the waterfront could attract up to 200,000 people and stem the estimated $50 million loss of economic activity caused by people leaving the city over the holiday weekend.
Auckland Tourism, Events and Economic Development turned down the air show because other events provided a greater return under the criteria for major events sponsorship, said Ateed's acting manager of major events, Jennah Wootten.
She said the air show was one of 86 events seeking $19 million in February from a limited budget of $2.25 million.
It was an "unproven idea" that was likely to attract Aucklanders instead of domestic and overseas visitors who met the criteria for economic growth, visitor nights and international exposure, she said.
Ms Wootten said the return of the V8 supercars to Pukekohe received $2.1 million a year from Ateed because of the estimated return the event would generate - $7 million a year in economic benefit and 50,000 visitor nights.
Aviation Industry Association chief executive Irene King said the air show and expo was a great opportunity to showcase the New Zealand aviation industry to the world.
