"Liv did a couple of great movies down there. She said New Zealand was gorgeous and green and was a place you have to visit."
The promoters mentioned going to Australia [the band will perform three shows there] and I thought that since we're going to be in that neck of the woods we might as well spread it out a bit.''
Details of the deal were announced by promoter McManus Entertainment and labelled a "major coup" by Dunedin Venues Management Ltd chief executive Darren Burden.
He said the show would be as big as it gets for the stadium.
"This is right up there ... it's good for the stadium and absolutely fantastic for the city,'' he said.
The size of the show meant there would be standing room only on the stadium's playing surface, lifting the venue's capacity to 40,000 fans, he said.
The event was expected to begin in the afternoon and continue late into the evening.
Tickets would go on sale on March 4, although prices and other details were yet to be confirmed.
However, with expectations fans would travel from around New Zealand and even from Australia, Mr Burden said he was hoping for a sellout.
Aerosmith formed in 1970 and would appeal to a wide age range, including Dunedin students, fans from elsewhere in New Zealand and even some ''die-hard'' supporters from Australia, he said.
''I think you will find there will be an awful lot of people that travel from all around New Zealand to come to this,'' Mr Burden said.
McManus Entertainment New Zealand general manager Jackie Sanders hoped the mix of support acts would also ''tip the balance and take this to a gig where it's going to be a 40,000 crowd''.
The announcement caps a stellar start to the year for the company running the stadium, which has so far secured headline events including Nitro Circus, Ride the Rhythm, Winery Tour, the Warriors, All Whites and Phoenix, and Grammy award-winning artist Paul Simon.
Ms Sanders said Aerosmith had time for only one show in New Zealand before continuing its Global Warming tour in Australia, and Vector Arena in Auckland was considered too small for the ''pretty huge'' show.
Promoters had assessed outdoor stadiums across the country before settling on Dunedin's roofed venue, because of the weather guarantees it offered, she said.
Equipment would be flown into North Island centres or Christchurch and then trucked or shipped by sea to Dunedin, she said.
''We are pretty confident we have made the right decision in coming to Dunedin and it's going to work for everybody,'' she said.
Mr Burden would not discuss details of the ''confidential'' deal between the parties, or say if DVML was guaranteed to make a profit.
Tourism Dunedin chief executive Hamish Saxton said news of Aerosmith's show would also be welcomed.
''I am certain the visitor economy will be delighted by another event of this magnitude hitting town ... there will be many businesses looking forward to this event.''
