A grand exhibition space which would house part of Te Papa's collection is being proposed for the Auckland waterfront.
The idea would see a distinct architectural structure, of approximately 24,000sq m on four floors, built in Wynyard Quarter.
It would act as a space for roaming exhibitions, rather than being a fixed museum or art gallery.
The proposal would expand the national Te Papa Tongarewa museum in Wellington and is to be put to the Auckland Waterfront Authority this month, by a group including art guru Hamish Keith and Te Papa chief executive Michael Houlihan.
Planning group chairman Mr Keith said the proposal was to give Te Papa national capacity by expanding into other parts of the country - in this case Auckland.
