Some of the land in the earthquake-damaged red zone in Waimakariri could again be used for housing, the district's mayor says.
Almost 100ha of land in Kaiapoi, Pines Beach and Kairaki was red-zoned after damage in the September 2010 and February 2011 earthquakes.
A draft plan for the long-term use of the land has been developed by the Waimakariri District Council.
Waimakariri mayor David Ayers said much of the land would be used for parks and recreation, but some could be used for mixed business or homes.
"As a building authority we need to be sure that the building is safe, so that's likely to make it fairly expensive.
"Having said that, rebuilding has occurred in the Kaiapoi town centre on both sides of the river so there is certainly interest on building on that type of land."
Mr Ayers said the report had gone to the Minister supporting Greater Christchurch Regeneration, Gerry Brownlee, who had put it out for a month of public consultation.
Kaiapoi's Silverstream Estates was fast-tracked using special earthquake legislation, but it was revealed yesterday up to 300 of the homes could be flood-prone.
