"What we'll see with Sylvia Park is that it will be a destination for people from the Bay of Plenty and from the Waikato - people will travel some serious distances to get there," he said.
"It's going to herald a new way of shopping and some of these other centres will be forced to up their game significantly."
Chris Gudgeon, chief executive of Kiwi Property which owns Sylvia Park, said both Zara and H&M would launch at a similar time late next year and he was thrilled to have secured the first Zara store in the country.
Kiwi Property plans to invest $11.5 million to accommodate Zara and is in the planning process of a 20,000sq m $140 million expansion for the mall, expected to begin in 2017.
