Christchurch City Council says all land within the central city can be rebuilt on.
The devastating earthquake on 22 February caused extensive damage to the city centre, most of which remains cordoned off.
As part of its final version of a draft Central City Plan, the council has released a geotechnical report by engineering consultants Tonkin & Taylor.
The report says no areas within the central business district or adjacent commercial areas have been identified as having ground conditions that would preclude rebuilding.
It adds, however, that more robust foundations or ground improvements may be required.
Christchurch mayor Bob Parker says the report is timely, as it will give land and property owners much more certainty and confidence about planning.
Mr Parker told Checkpoint on Tuesday that, while there will be increased costs for more robust foundations, the report gives certainty.
"I think the message is yes, there is a future on this land; yes we can be assured that we can build and rebuild actually something that would cope with the events that we've endured for the last 12 months or more."
Canterbury Earthquake Recovery Authority chief executive Roger Suttonsays the report shows the cost of rebuilding in Christchurch on average will be the same as in the other main centres - and that is a very positive step forward for the city.
