"It won't be on-site but it will be fairly close," Mr MacDonald said.
Demand for office leasing had been flat in the CBD for a number of years "but given what they are planning on doing to the building and given its location it is going to be towards the top of tenants' shopping list should they come to the market".
It has 270sq m to 540sq m options available, lift access and could be re-developed to suit new tenants.
The building's new owner had not yet settled "but obviously they are cracking on with things".
It was once the home of ANZ Bank until it merged with National Bank in 2012 and currently houses Pascoes The Jewellers and a nail salon.
Mr MacDonald said tenants' requirements had generally changed for the wider office market.
