Canterbury Green Zone building guides

The Ministry of Building, Innovation and Employment has released two Quick Guides for builders working in the Green Zones (TC1, TC2, TC3). Very useful for residents too.

They are:

  • The Guide for Canterbury Builders Below–Floor Work
  • The Guide for Canterbury Builders Above–Floor Work

Each Guide briefly outlines the regulatory requirements and highlights special issues. They can be downloaded from here.

Both are short and easy to read. If you are having work done you really should read them. If you are having a Fletchers EQR repair done these guides may help you know what to expect and to check what is actually being done.

The contents of the Below-Floor Work Guide are:

SETTING THE SCENE

  • Building in the Canterbury Green Zone
  • NZ Regulations
