The 2011 Christchurch earthquake took the lives of 185 people from 17 countries, and more than 1500 were injured.
More than half of the deaths occurred in the Canterbury Television (CTV) Building.
A state of local emergency was initially declared, which was followed by a national state of emergency.
It's a day the majority of New Zealanders will have a direct connection to, whether it be a first-hand account or via relatives or friends. It is also a day from which the city of Christchurch is still recovering.
Natural disasters have a harrowing habit of offering us a reminder of our vulnerability and what truly are the important things in life.
My thoughts yesterday were with those affected by the earthquake.
