Water Efficiency Labelling Scheme (WELS)

The Consumer Information Standards (Water Efficiency) Regulations 2017 mean certain products supplied or physically displayed for supply in New Zealand must display water efficiency rating labels.

The regulations require products imported into or manufactured in New Zealand to display the labels. These regulations do not apply to used goods, meaning equipment that has already been used by a person in New Zealand. When offering to supply products on the internet, reproductions of the labels must be displayed or alternatively, the information specified in regulation 13 provided.

From 1 October 2017, suppliers of water-using equipment covered by the Regulations can comply with either:

  • the Consumer Information Standards (Water Efficiency) Regulations 2010; or
  • the Consumer Information Standards (Water Efficiency) Regulations 2017.

From 30 September 2019, all suppliers must comply with the 2017 Regulations.

WELS applies to six product classes:

  • clothes washing machines
  • dishwashers
  • lavatory equipment
  • showers
  • tap equipment
  • urinals.

You can find more information about WELS is on the Ministry for the Environment website .
