The Christchurch City Council has granted a critical resource consent which means substantive reinstatement works on the Christ Church Cathedral site can begin.
While physical work on stabilising the Cathedral began in May this year, the consent allows for the repair and restoration of heritage fabric along with the replacement of the west porch, tower and vestries on the main building.
It will also enable the superstructure of the main cathedral building to be seismically strengthened.
Christ Church Cathedral Reinstatement Ltd project director Keith Paterson said the granting of the consent is a major milestone.
