According to Marija Gecan, general manager sales - Auckland Conventions Venues & Events, the refurbishment will create a contemporary, modern venue to welcome and inspire local and international visitors.
The exterior will be modernised, with features including stainless steel interlocking plates over new stone panels, and glass balustrades.
Environmentally friendly upgrades include a green roof space with natural vegetation that will provide additional external areas for delegate breaks and hostings.
Gecan says there will be a floor-to-ceiling glass entryway, striking atrium artwork, fresh lighting, and modern floor and wall treatments will create a vibrant ambience, with digital wayfinding provided on all levels.
New foyers will provide enhanced exhibition space, and a refresh of all the conventions spaces will complement the recently refurbished 2000-seat auditorium.
The refurbishment will also include new bar areas for delegates to meet and network.
