The Building Industry Federation says a slowdown in demand for building supplies means there will be no shortage of material to fix houses damaged by the earthquake in Canterbury.
Fletcher Contruction is to manage the repairs to 50,000 homes damaged by the magnitude 7.1 earthquake on 4 September.
The company expects to employ up to 400 people to manage the rebuilding projects and hire thousands of subcontractors.
The of the Building Industry Federation says the industry overall has been operating at about 60% of capacity for some time.
Chief executive Bruce Kohn says it will not be difficult to meet the rebuilding demands.
