At the time, it was estimated to be worth more than $15 million to the Auckland economy, attracting 65,000 visitors
Originally it was held at Auckland's Ellerslie Racecourse, before it moved to the Botanic Gardens in Manurewa in 1998.
In 2008, a replacement flower show was held at Alexandra Park.
Ms Hiller said next year's show would be "huge for Auckland".
She said international names had already registered their support for the event - including Chelsea Flower Show Gold medal winning South African Leon Kluge and Singapore Garden Festival winner Jim Fogarty.
The show will have a focus on community and culture, and organic and edible gardens will be a feature.
Bastion Point played a significant role in land protests during the 1970s, and the land was returned to its original Maori owners Ngati Whatua in the 1980s.
Ngati Whatua Ōrākei spokesman Wayne Pihema said the iwi was excited to see the land used for the show.
"We are committed to the preservation and restoration of the flora and fauna on our whenua to a state where the mauri, or life force, of the land is thriving.
"It is fitting that Bastion Point should be a meeting place for designers of all nations who share our love of the visual and spiritual properties of plants," he said.
