The Civic Building, where 500 staff now work, will either be sold, refurbished or demolished and 2400 people will come from there and elsewhere to Albert St. All up, 6000 council staff work at Takapuna, Henderson, Manukau and elsewhere.
The Civic has asbestos on every floor and although some has been removed, it remains around lift wells and in the corners of all floors, McKay said.
"We want to start populating 135 Albert St by early 2014 and then it will be progressive over a five to 10-year period."
No relocations are planned from offices at Manukau or Henderson but when staff leave Takapuna in 2022 after that lease ends, average annual savings for the council would be closer to $5.1 million, McKay said.
The council, with $3.5 billion borrowed, is funding the tower purchase via debt instruments.
Last week, the council announced the deal to buy the tower from Bookfield Multiplex. Allan Matson of the Auckland Society for Amenity Protection has doubts about the shift.
"I would have thought the civic administration should look over the civic space rather than going into commercial premises."
Property investor Tim Duffett of Newmarket also wondered about the purchase and said it was easier to deal with civil officials in Las Vegas than in Auckland.
