Regulation Impact Statement for Consultation: Energy Efficiency Policy Options for Heat Pump Water Heaters HPWHs (September 2025, 110 pages).

1.    Business as Usual option involves no change to the current situation i.e. no specification of minimum energy performance standards or the implementation of any requirement for voluntary or mandatory provision of information on the operation and performance of HPWHs.

2.    Develop minimum energy performance standards (MEPS) to be set at the equivalent of the current minimum requirements for Small-scale Technology Certificates in Australia (equivalent to 60% energy savings in Zone 3) and a voluntary information provision.

3.    MEPS (as per option 2) and mandatory information provision requiring heat pump water heaters (HPWH) suppliers to provide information on the performance of their products displayed either via a mandatory product label and the use of mandatory requirements to include performance information in all product marketing provided by the supplier for the unit.

In addition to the policy options, the Regulation Impact Statement for Consultation (CRIS) examines technical considerations such as test methods, standards, and the information that could be required to be displayed that impact the options.

New Zealand's preferred option at this stage is Option 3, which combines minimum energy performance standards with mandatory information provision to ensure consumer confidence and support emissions reduction goals.
