Among the crowd were Jaime Ridge and her boyfriend, Josh Bloxham, as well as Mayor Len Brown, Michelin-star chef Josh Emett and his wife, Helen Cranage.
Most of the mingling took place on the store's ground level, which features black and white marble chequered flooring typical of many Prada stores around the world.
A selection of the label's pieces, which included the $3795 Saffiano Cuir Double Bag and a pair of $610 red flats, were displayed on glass shelves.
Part of the first floor has also been designated as a private viewing area for regular Prada customers who can sip champagne on the couch while viewing pieces brought to them by staff. They also have their own changing room and can relax on a couch overlooking Queen St.
The floor is accessible by a crystal elevator or black marble staircase.
Francis Hooper, co-owner and designer of World, said it was great to finally have a Prada store in Auckland. He said the store, which is near other high-end brands Gucci and Louis Vuitton at the bottom of Queen St, would be a big hit.
"It's going to go off, Auckland's a big city," Mr Hooper said.
"It's not about practical needs, it's about desire."
