Westpac has confirmed that a staff member at its head office has tested positive for Covid-19, and employees are being asked to monitor their health.
The bank spokesman said the non-customer facing employee contracted it from a close contact.
"As soon as they became aware a member of their household had contact with a Covid-19 case, the employee self-isolated. The self-isolation started last Friday evening and official advice is that the staff member would not have become infectious until Tuesday of this week."
However, the spokesman said, as a precaution, the bank was deep cleaning the workspace and floor where the staff member worked.
