The former BNZ Tower in Wellington, more recently known as the State Insurance Tower, will become the Aon Centre on Sunday.
Its construction for the Bank of NZ began in 1973, but a demarcation dispute over who should weld its structural steel not only stopped work on this tower but tilted highrise developers heavily in favour of structural concrete.
A second construction contract was needed to complete it, in 1984. The BNZ moved its head office to Auckland in 1998 and State Insurance took on naming rights.
Insurance brokerage Aon has been a tenant since 2013.
Precinct Properties NZ Ltd owns & manages the building, which fronts Lambton & Customhouse Quays as well as Willis St. It has 22 office floors, 3 parking levels, underground & ground level retail arcades and a foodcourt.
