Christchurch City Council's Ōtākaro Avon River corridor regeneration committee has issued a request for information to gauge interest from housing providers on some edges of the red zone.

The process covers 12 hectares of edge housing areas within the 602-hectare corridor, representing 2% of the total land. The committee said edge housing could be suitable for limited residential development designed to front open spaces and improve integration between existing neighbourhoods and the regenerated corridor.

Committee chairman Nuk Korako said red zone land sales were not currently being considered, adding "whether that housing eventually involves sale, long-term lease or partnership, that's a separate decision, that hasn't been made".
