Dear Electricity Authority,

Please find below my Official Information Act request relating to approved smart meter models, technical test standards, and recorded incident statistics. This request is made in the public interest as part of an active Utilities Disputes complaint (Ref 173878) concerning appliance damage and smart meter performance.

Pursuant to the Official Information Act 1982, I request the following information relating to all smart electricity meters currently or formerly approved for installation in New Zealand:

1. The complete list of all smart meter models approved for use in NZ from 1 January 2015 to the present, including:
- Manufacturer name
- Model designation
- Firmware version(s) approved
- Date of approval and, if applicable, withdrawal

2. Copies of all technical specifications, compliance certificates, and test reports held by the Authority or MBIE for each approved model, showing:
- Surge immunity testing (fast transient/burst and surge per IEC 61000‑4‑4, 61000‑4‑5, or equivalent)
- Electromagnetic interference (EMI) emission levels, including conducted and radiated emissions
- Any high‑frequency transient event immunity testing
- Testing for compliance with NZS 2772.1:1999 and any supplementary EMF/EMI standards

3. All internal or external correspondence, reports, or minutes discussing whether the above tests are mandatory for approval, and whether immunity to “dirty electricity” or conducted transients is assessed.

4. Incident/fault statistics held from 1 January 2015 to the present, broken down by meter make/model, for:
- Reported appliance damage

If any part of this information is withheld, please state the exact grounds under the OIA, specify the subsection, and explain the public interest test applied under section 9(1).
