Regenerate Christchurch is seeking feedback on its outline for developing the earthquake-damaged red zone land along the Avon River.
The government agency said its draft regeneration plan for the Ōtākaro/Avon River Corridor was the mandatory first step in the process.
Chief executive Ivan Iafeta said the new plan would cover the whole corridor instead of the smaller area that was first indicated, because feedback had shown that was what the community wanted.
People can comment on the draft outline until 21 February.
