Auckland Transport is in the middle of two different sets of roadworks on Park Road, both of which are taking place after hours. Both require concrete cutting into all hours of the night.
The first is the realignment of the Grafton Station bus stop. It is well advanced.
The second is the installation of CCTV compliance cameras along Park Road. AT did provide households with a vague notice about 10 days ago, but the detailed notice of works has only just arrived for many residents, after work had commenced. Please read the document linked above for all the gory details.
These are the locations where camera poles and associated cabling are being installed, and will entail late night disturbance to residents.
