The right-hand lane of Molesworth Street will be reopened for traffic and pedestrians will be able to use the footpath on the side of the street furthest from the demolition site at 61 Molesworth Street.
The cordon has been in place since it was established that the multi-storey office building at 61 Molesworth Street was in danger of collapse after the 14 November earthquake.
There will be no parking on Molesworth Street between Aitken Street and Hawkestone Street.
Full access to and occupation of 100, 102 and 118 Molesworth Street and the internal section of rear of the Wellington Cathedral will be allowed.
A smaller cordon around 61 Molesworth St and some of the surrounding properties will remain in place as the demolition continues. Shipping containers have been placed on the left hand side of Molesworth Street to provide additional segregation between the road and the demolition site and to allow for the easy movement of large trucks that are removing debris.
Further reductions of the cordons will take place as work progresses. Access to the Red Cross building and Collina Terrace properties adjacent to 61 Molesworth Street will likely be allowed in coming cordon reductions, the first due before the end of the year after the tower comes down.
