The Government is preparing to deal with the contentious earthquake-prone building issue, deciding the fate of up to 25,000 old buildings.
On Wednesday, the Cabinet economic growth and infrastructure committee is due to consider Building Act changes requiring all non-residential and multi-unit, multi-storey residential buildings to be seismically assessed within five years and upgraded within 10 years.
The issue is then due to go before the Cabinet next Monday, depending on Wednesday's outcome.
More than 1000 people attended meetings on the issue, which drew 535 submissions, earlier this year.
Building and Construction Minister Maurice Williamson said the Government wanted to introduce a consistent national approach to dealing with earthquake-prone buildings following the Canterbury earthquakes.
