He said the residential red zone offer scheme had allowed property owners to move on from the most damaged areas promptly and the Government's assistance had progressed recovery much faster than if the usual private insurance process had been left to handle the situation.
"Some parts of residential Christchurch were so damaged by the quakes that if we hadn't acted decisively property owners would have been left in a state of quagmire, both physically and metaphorically," said Mr Brownlee.
Mr Brownlee said the completion of the zoning process would allow people to move with their lives.
"When we started this process we knew it would not be easy and we knew the end results would not please everyone."
Christchurch Mayor Bob Parker said the council and Christchurch Earthquake Recovery Authority have worked hard to establish the best option for what was an unusual situation in the Lucas Lane area.
"By the end of May next year this hazard will have been removed and the owners of the homes directly threatened by it will be safe," he said.
