The February 2011 magnitude 6.2 Christchurch earthquake was triggered by the magnitude 7.1 Darfield earthquake five months earlier. Unlimited Paenga Tawhiti could not return to its central city buildings due to demolitions and it has no long term site. Each individual can react differently to traumatic events, and more research needs to be done to learn how to predict vulnerability and access the effects to find solutions that work best. A (M) 6.3 earthquake (the Christchurch Earthquake) occurred on 22 February 2011. , Gerry Brownlee, a Cabinet Minister, had his regular portfolios distributed amongst other cabinet ministers so that he could focus solely on earthquake recovery..

New Zealand's GNS Science has stated that the earthquake was part of the aftershock sequence that has been occurring since the September magnitude-7.1 quake, however a seismologist from Geoscience Australia considers it a separate event given its location on a separate fault system. , The earthquake was a "strike-slip event with oblique motion" which caused mostly horizontal movement with some vertical movement, with reverse thrust causing upwards vertical movement.  On 1 March, it was announced that the New South Wales Government would be donating A$1 million (NZ$1.3 million) to the victims of the Christchurch earthquake.

New Zealand's Earthquake Commission (EQC), a government organisation, levies policyholders to cover a major part of the earthquake risk.  Road surfaces were forced up by liquefaction, and water and sand were spewing out of cracks. , The Forsyth Barr Building survived the earthquake but many occupants were trapped after the collapse of the stairwells, forcing some to abseil out after the quake.  Power had been restored to 82% of households within five days, and to 95% within two weeks.  Depressive symptoms before a disaster can predict higher chances of developing PTSD following a trauma. Location of the 12:51pm quake epicentre within Christchurch. The humble domestic concrete slab is a very important component in getting things right first time. Initial reports by GNS Science suggested that ground motion "considerably exceeded even 2500-year design motions", beyond maximum considered events (MCE).
