More than 500 people, including grieving family members who lost loved ones in New Zealand's worst natural disaster, have gathered at a civic memorial service in Latimer Square today.
The New Zealand flag fluttered at half-mast as Mayor Parker spoke about the "dreadful, frightening, terrible" magnitude-6.3 quake which struck two years ago at 12.51pm.
A rebuilt Christchurch must honour the 185 people who died in the February 22 earthquake, Mr Parker said.
The crowd was smaller today than last year, he said, but he told those there that people around the city, New Zealand and the world were looking on today and remembering what Christchurch had gone through.
Prime Minister John Key said February 22 would always be a poignant day for the people of Canterbury.
Addressing grieving families, he said: "I know it's a difficult day for you. Your grief is still raw and only time can numb the pain of your loss. The city and country still feels for you."
He paid tribute to the "strength and resolve of Cantabrians" who have lost homes and businesses and suffered disruption and anxiety.
"In the face of it you've shown great heart and resilience. You have prevailed."
The anniversary was a chance to look forward also and reflect on how far its come.
He said Christchurch would become one of the best and liveable cities in the world.
