The Lyttelton Timeball Station is a heritage-registered time ball station and prominent local landmark in Lyttelton, New Zealand. The original station was significantly damaged by a series of earthquakes and aftershocks in 2010 and 2011, and finally collapsed on 13 June 2011 after a magnitude 6.4 aftershock. The tower was subsequently reconstructed, reopening in November 2018.

The June 2011 Christchurch earthquake was a shallow magnitude 6.0 Mw earthquake that occurred on 13 June 2011 at 14:20 NZST. It was centred at a depth of 7 km (4.3 mi), about 5 km (3 mi) south-east of Christchurch, which had previously been devastated by a magnitude 6.2 MW earthquake in February 2011. The June quake was preceded by a magnitude 5.9 ML tremor that struck the region at a slightly deeper 8.9 km (5.5 mi). The United States Geological Survey reported a magnitude of 6.0 Mw and a depth of 9 km (5.6 mi).
