"These things all together make for a fantastic package and start making Auckland look like a world-class city like San Francisco, Sydney or Hong Kong. The timing is superb because the economy is starting to move again. There's a fresh confidence in Auckland and particularly around the importance of the waterfront as a public place," Coop said.
But Shamubeel Eaqub, NZIER principal economist, warned against talking up the situation and predictions of a $500 million gain.
"With the America's Cup, there will be a lot more economic hype than reality," he said.
"There will definitely be construction work done, if it comes to New Zealand. But beyond that, I am not sure how much of it will be new as opposed to stuff that would have been done anyway that will now be fast tracked. The economic benefit numbers being touted by some economists I see is half a billion dollars. Based on the performance of these types, its probably going to be a tenth of that.

Convention centre completion timing could be perfect.
"Rugby World Cup resulted in a lot of projects being fast-tracked," he said, citing Wynyard Quarter's transformation and further projects there.
"America's Cup racing reinforces Waterfront Auckland's plans."
David McConnell, Auckland Tourism Events and Economic Development chairman and a Hawkins Group director, said the combination of all the big new projects, along with a significantly more stimulated visitor economy, would be a catalyst for accelerating Auckland's economy.
