Buy water efficient products (WELS)

WELS labelHow much water an appliance or bathroom fitting uses can vary greatly from one make or model to the next – for example, a water-efficient clothes washer can use less than half the amount of water per cycle as a same-sized inefficient model. Now, New Zealand has a labelling scheme to help you sort out the water-efficient models from the rest.

The New Zealand Water Efficiency Labelling Scheme (WELS) provides consumers with information about how efficiently products such as washing machines, showers and taps use water – via labels on new products in shops and showrooms.

How the WELS labels work

The WELS label displays two key pieces of information:

1. a star rating indicating relative water efficiency

2. a water use or water flow figure

Each product label displays a star rating out of six – the more stars, the more water efficient (showers currently have a maximum star rating of three, as there is not yet a laboratory test to ensure very low-flow shower products deliver acceptable performance. You can find a Consumer test of shower performance here).

What does WELS cover?

The WELS label applies to six product classes:

  • Clothes washing machines
  • Dishwashers
  • Toilets
  • Showers
  • Taps
  • Urinals
