Scope of the technical investigation

The focus of the technical investigation was to look at the structural performance of each building and to identify where possible, the cause or causes of building failures. It was not intended to address issues of culpability or liability. These matters were outside the scope of this investigation.

Expert panel

MBIE appointed leading New Zealand engineering consultants to investigate each of the buildings. It also established an Expert Panel to oversee their work, provide guidance on the methodology of the investigations and peer reviewed the findings.
