Please note, more detailed information for each case is withheld under section section 9(2)(ba)(i)
of the Act, to protect information that is subject to an obligation of confidence and making it
available would likely prejudice the supply of similar information, or information from the same
source.
Market audits or reviews involving metering accuracy or certification
This part of your request is refused under section 18(d) of the Act, as the information is publicly
available here: Audits and certifications | Electricity Authority.
Any reported systemic issues concerning AMI deployment (aggregate level only)
This part of your request is refused under section 18(g) of the Act, as the information is not held by
the Authority. We sought transfer with WorkSafe on this part of your request, but they advised they
would not hold any information in scope either.
