Christchurch City Council says its deliberations about public submissions on the draft central city plan are taking longer than expected because there are so many.
About 3500 submissions have been presented to the council in writing and at public hearings.
Mayor Bob Parker says the council had hoped to be finished by the end of last week but it is now likely deliberations will continue until Wednesday.
Mr Parker says one of the most contentious issues is the proposed seven storey height restriction on new central city buildings.
He says once the council has completed its deliberations the central city plan will be rewritten with the aim of handing the final plan to the Government by Christmas.
