The service will begin at 12.30pm on February 22 at the north bank of the Canterbury Earthquake National Memorial site on the corner of Montreal St and Cambridge Tce.
It is expected to take about 45 minutes, and will be followed by the opportunity for people to lay floral tributes at the Memorial Wall across the river.
The service will also be filmed using multiple cameras and streamed live.
Christchurch Mayor Lianne Dalziel will offer some words of welcome at the start of the service and then the names of the 185 people who lost their lives in the earthquake will be read in the order they appear on the Memorial Wall.
At 12.51pm - the exact time the earthquake struck - a minute of silence will be observed.
At the end of the minute’s silence, a poem will be read by members of the Quake Families Trust.
Leopard Coachlines Canterbury Brass will then perform Elgar’s Nimrod ahead of a closing karakia and blessing.
At the end of the service people will be invited to cross to the south side of the earthquake memorial and pay their respects at the Memorial Wall.
People are welcome to bring flowers and drop them in the Avon River as they cross the bridge to create a ‘river of flowers’.
Those planning to attend the service should arrive at the memorial site by 12.20pm.
The City Promenade will provide pedestrians and cyclists with access to the service and temporary cycle stands will be placed on Cambridge Tce.
Limited seating will be provided for invited guests and those unable to stand for the duration of the service.
