The council had long-term property needs so it made more sense to buy than lease new headquarters, he said. The focus of those involved in the deal was more on buying the ASB centre than the Civic Building because one had to be secured before the old one's fate was resolved.
Brookfield Funds Management owns the 33,443sq m ASB tower, held in the unlisted A$360 million ($459) Australian-owned Multiplex New Zealand Property Fund.
That block is on a prominent corner on the southwestern end of the central business district and has frontages to Albert, Wellesley and Federal Streets. The building has four levels of basement parking, a large entry foyer and 30 levels of column-free office floorspace.
Services are premium grade, including a full back-up emergency generator, Brookfield said.
About 3500 council staff are in the CBD but around 8000 are spread across the wider city area.
Private multimillionaire family-owned commercial property investor and developer Manson TCLM is understood to be helping some ASB tenants shift by buying shorter-term leases and offering those businesses new leases on other premises.
"They're buying tails-up on leases which is clearing the building out to make way for the council. It's how Manson's are tenanting their buildings," a consultant said.
