Air conditioners and heat pumps

Air conditioners and heat pumps must comply with minimum energy performance standards (MEPS) if they’re to be sold in New Zealand.

MEPS currently apply to single phase and three phase units and multi-split units. Single-phase non-ducted air conditioners and heat pumps must also display the energy rating label.

The MEPS and labelling requirements are currently under review and a number of changes are proposed, including:

  • Updating the energy rating label and calculation method to show how products perform in different climate conditions, using a Zoned Energy Rating Label. 
  • Aligning New Zealand MEPS levels for cooling with Australian levels.
  • Expanding the scope of MEPS to include single-duct portable units and a wider range of commercial units.

Two rounds of consultation on this proposal occurred in 2016 and final decisions on this proposal are being made within the coming months.

More information on this proposal and the consultation that has occurred is available on the Energy Rating website.
