Nelson St will remain closed between Victoria St West and Fanshawe St and is not expected to re-open to traffic until at least the middle of this week.
School holidays also kicked in over the weekend, with the first official day starting today, meaning traffic levels will be down.
The man representing the corporate body for the repair works of the building, Ian Harris, told the Herald on Friday more loose panels had been found.
By lunchtime yesterday, workers were expected to have finished fitting plywood sheets to the corners of panels needing reinforcement, he said.
This will allow a team of abseilers to throw netting over the remaining half of the Victoria St facade. Netting has already been thrown over the other half of the facade.
The closure of Nelson St will allow work to continue applying plywood sheets on the Nelson St facade of the apartment tower.
Emergency services were forced to close the street block after a cladding panel was blown off the Victoria St apartment building about 10.45am on Thursday.
A witness said she heard a "very loud bang", then saw dust fly up from behind a construction fence when the panel fell just after 1pm.
Several pedestrians on the footpath below had visibly jumped at the impact before retreating to a covered tunnel.
The Auckland apartment building from which the panel fell is subject to $40 million of remedial work which began in March.
AT advises further lane closures are anticipated at off-peak times during the week to allow scaffolding to be put in place.
