A number of central city streets are closed today while scaffolding materials are helicoptered to the top of the Auckland Council headquarters in Albert St.
Several streets round the building were closed at 5am and due to be reopened at 5pm.
Up to 70 helicopter lifts are taking place from 9am.
Closures include Wellesley Street from Albert to Hobson Streets, one lane closure outside the Council building on Albert Street and restricted access to parts of Federal Street.
A council spokeswoman said neighbours, including church leaders at nearby St Matthews in the City, were consulted about the work.
