First draft of quake-proof law was an over-reaction, but the revised version is practical and affordable.
In the aftermath of a disaster it is easy to lose your head. That is what happened when a royal commission of inquiry into the Canterbury earthquakes, followed by a building code review, suggested all New Zealand's older buildings of unreinforced masonry should have to comply with the modern code as soon as possible.
The royal commission recommended that councils be given two years to identify substandard buildings and after that, the owners be given seven years to upgrade or demolish them.
The Ministry of Business, Innovation and Employment was a little more lenient. Its code review proposed five years for identification of non-compliant buildings and a further 10 years for their strengthening. The Government adopted periods of five and 15 years in a bill introduced to Parliament when Christchurch had barely stopped shaking.
Fortunately the Earthquake-prone Buildings Amendment Bill has been delayed long enough for better judgment to prevail. This week, Building and Housing Minister Nick Smith announced the bill would be revised to give variable periods for compliance depending on the building's location. The country is to be divided into three broad zones of high, medium and low risk, depending on their distance from the collision of tectonic plates that created our shaky isles.
