Our expert engineering panel provides technical and expert advice to help resolve insurance claims through the GCCRS.

The Panel is administered by Engineering New Zealand and is independent of the Courts, insurers and homeowners. 

The GCCRS makes a request to Engineering New Zealand for the panel’s services, and Engineering New Zealand directly and independently engages a panel member to carry out that service. There is no cost to homeowners to access the Panel’s services through the GCCRS.

Services provided by the Panel

Initial appraisals

GCCRS can ask a Panel Member to carry out an initial appraisal. This could be under a joint instruction from the homeowner and the insurer. 

Its purpose is to determine steps that could be taken to resolve the claim. 

It typically involves a conversation with the homeowner about their observations of earthquake damage or inadequate repairs, a visual assessment of the home, and a brief report about issues that could require another process under the GCCRS.

Peer review

GCCRS can ask a Panel Member to carry out a peer review of an engineering assessment of earthquake damage and reinstatement recommendations for a home. 

The peer review can include advice about whether sufficient investigations have been carried out, the evidence supports the findings, the correct standards have been applied, and the conclusions in the report are robust.

Expert advice

A Panel Member can be asked by the GCCRS to provide independent expert engineering advice during a determination of an insurance claim. This would involve acting in accordance with the High Court Code of Conduct for Expert Witnesses.

Engineers on the Panel

The Panel was appointed by the Engineering New Zealand Board on the recommendation of a cross-stakeholder evaluation team. 

The evaluation team included senior engineers, a homeowner advocate, a barrister who works exclusively for homeowners, and a lawyer who works for both insurers and homeowners. 

Engineers were recommended to the Panel based on a number of factors, including their technical expertise, experience and cross-stakeholder acceptability.
