The Lyttelton Timeball Station was erected in 1876 and started signalling Greenwich Mean Time to ships in the harbour that year . It was one of the world 's five working timeball stations until it was destroyed by the June 2011 Christchurch earthquake . The castle-like building was located high on a ridge above the port with extensive views over the harbour . The tower , but not the rest of the building , has been faithfully reconstructed and was once again in working order at the end of 2018
