"It will finally allow people like the Quake Outcasts who have been stuck in limbo to move on with their lives."
Labour has also vowed that it will not use compulsory acquisition powers against red-zone property owners.

"It is fair in the sense that all residents are treated equally, and that given any new government will inherit the red zone mess left behind by the National government, a policy that addresses the discrimination issue is a huge step forward."
The Supreme Court is due to hold a hearing to determine whether the residential "red zone" was lawfully established on July 29-30.
