Choose water efficient appliances

The easiest way to ensure you are installing water efficient appliances and fixtures is to use the water efficiency labelling scheme (WELS). Look for the blue stars – the more stars, the more water-efficient the product. The WELS rating can help you to select your:

  • taps
  • washing machine
  • dishwasher
  • toilet
  • shower.

Find out more about the Ministry for the Environment’s Water Efficiency Labelling Scheme.



When choosing a shower head select one with a high WELS rating. Contact us to see if you are eligible for a free water efficient shower head*.


If you are installing a bath, look at the shape and size of the bath and choose one that holds a lower volume of water.


Ditch the waste disposal unit and use a worm farm or compost instead.


Choose a tub that has a water efficient tap.


If you are installing pipes in the ceiling, consider wrapping them with insulation (known as lagging) to prevent heat loss in the summer and overheating in the summer. This will avoid you needing to run your tap for ages before you get hot water or cold water in summer.

*Residents of Hamilton, Waipā & Waitomo District may be eligible for a free replacement water efficient shower head.

Outside your new home


When planning your outdoor landscape, use materials that allow rain to soak into your soil and garden.


When paving, use porous material or ground cover in the gaps instead of mortar.


Be selective on what, when and where you plant in your garden, including a drought tolerant lawn.

Install a rainwater collection system to harvest water from your roof. For more information check out our rainwater harvesting tips.


Consider installing a drip line irrigation or soaker hose - these are two of the best ways to water shrubs, plants and vegetables, as they water the root zone directly.

Choose a smart irrigation timer that only switches on when plants need it e.g. if rain is forecast, the irrigation system will not turn on. Most devices are operated via a simple smart phone app. Check out Jared's experience of using a smart irrigation device.


When building a swimming pool invest in a water efficient pool filter and a good fitting pool cover which will help to reduce evaporation. Around the pool area, strategically place trees and shrubs to give your pool protection from wind and provide shade which will also help reduce evaporation and keep swimmers protected from the sun.
