Christchurch City Council says it will appoint four companies to carry out repairs on water supplies, sewerage infrastructure and roads damaged in the Canterbury earthquake.
The region suffered extensive damage from a 7.1 magnitude quake on 4 September.
It is estimated the damage will cost $290 million to fix. City Care, Downer NZ, Fulton Hogan and McConnell Dowell-Fletcher Construction will manage the repairs.
The council says it aims to get contractors working as soon as possible in the worst-affected areas which include Hallswell, Brooklands, Southshore, Bexley, Avonside, Burwood and Dallington.
Repairs on roads and sewers outside those areas will be done at the same time.
The council says it will also allow the Earthquake Commission to carry out remediation on damaged council-owned esplanade and road reserve land.
