A suppliers’ guide to the New Zealand Water Efficiency Labelling Scheme

Publication date:  May 2010
Publication reference number:  ME 1006

This booklet is currently being updated and contains obsolete information. It provided information for people who import, manufacture, or sell products covered by New Zealand’s Water Efficiency Labelling Scheme (WELS). The WELS products are:

  • clothes washing machines
  • dishwashers
  • lavatories
  • showers
  • taps
  • urinals.

Under the Consumer Information Standards (Water Efficiency) Regulations 2010 made under the Fair Trading Act 1986, New Zealand importers and manufacturers are responsible for ensuring products they import or manufacture are tested and meet the labelling requirements of this regulation. Retailers are responsible for ensuring WELS labels are displayed with these products at point of sale including online.

WELS labelling provides clear information to consumers on a product’s water efficiency and water consumption in a standardised form, to help them choose products that use less water to perform the desired function.
