A controversial new $50 million dome-shaped silo for storing cement has been inflated on Auckland's waterfront.
The state-of-the-art 28m-high silo holds 30,000 tonnes of cement and is located at a Ports of Auckland site on the corner of Plumer and Quay Sts opposite Vector Arena
The dome's outer skin is made of a membrane similar to that used to build the Cloud on Queens Wharf.
Consent to build the silo was granted on a non-notified basis, meaning the public did not have a say, angering groups concerned about the port's growing footprint on the waterfront.
Holcim New Zealand country manager Glenda Harvey said the storage dome signalled a major milestone for the company.
Holcim was investing $100 million in building two 30,000 tonne new storage facilities in Auckland and Timaru as part of its business strategy of global sourcing for supply into the New Zealand market.
