Red Zone
The Central City Red Zone, also known as the CBD Red Zone, was a public exclusion zone in the Christchurch Central City implemented after the 22 February 2011 Christchurch earthquake. After February 2013, it was officially renamed the CBD Rebuild Zone by government agencies, but remained known as the Red Zone. It gradually shrank in size and the last cordons were removed on 30 June 2013, 859 days after the earthquake.
