Summary
EECA’s web-based Efficient Appliance Calculator (eeca.govt.nz/for-homes/energy-saving-technology/efficient-appliance-calculator/) lets NZ households filter and compare energy-efficient regulated appliances by model number or product name. The clipped landing page captured 2026-05-30 is wrapper text only; the actual calculator is a dynamic JS form. The single substantive disclaimer recovered via WebFetch (2026-05-31): “The information in this calculator is only a guide to help you compare products. Product details and efficiency ratings are supplied by New Zealand manufacturers and importers who have chosen to register products.”
Key insights
- NZ’s residential appliance efficiency comparison is delivered via EECA’s web calculator — the public-facing UI on top of the trans-Tasman E3 (Equipment Energy Efficiency) programme + MEPS (Minimum Energy Performance Standards) + Energy Rating Label scheme that NZ co-administers with Australia. Useful as the canonical NZ consumer-facing reference point for appliance efficiency, cross-referencing with the 8-action efficiency table in OT_026 (which specifically names LED lighting + appliance shifting as two of the eight).

- Critical methodology caveat: opt-in manufacturer registration. The calculator’s data is supplied by NZ manufacturers and importers who have CHOSEN to register products. Coverage is therefore partial, not exhaustive — non-registered products + parallel imports + older installed stock are invisible to the calculator. NI implication for residential appliance modelling: the calculator gives a defensible REGULATED-PRODUCT-MARKET efficiency band but does NOT reflect actual installed-base efficiency (which lags due to long product life, second-hand market, and non-registered units). For Lower Moutere baseline assumptions about household appliances, treat calculator output as the upper-bound of efficiency available to NEW purchases, not the typical household’s current appliance efficiency.

- The substantive data lives in the underlying trans-Tasman Energy Rating database (NZ co-administered with Australia’s Department of Climate Change, Energy, the Environment and Water; database at energyrating.gov.au with NZ-specific extracts). The calculator is a thin UI on top of this dataset. RT_149 captures retrieval of the actual product-registration database if appliance-efficiency parameters become load-bearing for NI residential demand modelling. → NOW HELD: the register extract is ingested as RD_025 (8 regulated categories, ~23,504 models, 15 Jul 2026) — RT_149 partial: whitegoods + HVAC + electronics + pool pumps delivered; lighting and hot-water/water-heater categories still outstanding.

Research targets
Documents to retrieve
- RT_149 (medium) — Trans-Tasman Energy Rating product registration database (energyrating.gov.au). The actual substantive dataset behind the EECA calculator. Provides per-product kWh/yr ratings, star ratings, MEPS compliance status across NZ + AU regulated appliance categories (whitegoods, HVAC, lighting, electronics, hot water). Should retrieve when NI residential demand modelling needs defensible per-appliance efficiency parameters for Lower Moutere baseline or post-efficiency scenarios. Available via direct download or API.
