Viaduct Basin is now known as Viaduct Harbour. It is a former commercial harbour on the Auckland waterfront, now turned into a development of mostly upscale apartments, office space and restaurants.
It is located on the site of a formerly run-down area of the Freemans Bay / Auckland CBD waterfront in Auckland City, New Zealand. As a centre of activity of the 2000 America's Cup hosted by the Royal New Zealand Yacht Squadron, the area enjoyed considerable popularity with locals and foreign visitors.
