The fate of Auckland Council's distinctive 19-level Civic Building beside Aotea Square will not be decided until after the deal for the new premises is completed.
Last month, the council said it would soon announce where it would shift hundreds of staff from the civic headquarters which has a range of problems including weathertightness and facade issues.
Negotiations to buy the ASB Bank Centre on Albert St for around $100 million are understood to be nearing completion.
One party close to the deal said that did not mean the Civic Building was unfit for purpose, just that new premises would better suit the new Super City model.
Just because the older structure failed to meet the current Building Code did not mean it was dangerous, he said. No 1950s tower would meet that, he said, because the code was continually being upgraded.
