15 water saving tips for homeowners in New Zealand

Water is a precious resource that should be conserved by everyone. Homeowners in New Zealand can play a significant role in reducing water consumption by implementing various water-saving measures.

Conserving water is going to be essential for the long-term sustainability of the planet. Whilst many of us think about the benefits around the home, conserving water stretches far beyond our own backyards. Water is a precious resource that is used in agriculture, industry, and recreational activities to name but a few.

With the demand for water increasing throughout the world, it is important that we all do our bit to conserve water and ensure there is enough water for future generations.

Here are some practical water-saving tips for homeowners in New Zealand:

1.     Install low-flow showerheads and taps

One of the simplest and most effective ways to save water is to install low-flow showerheads and taps. These fixtures restrict the amount of water that flows through them, reducing water consumption without compromising on the quality of your shower or the effectiveness of your tap. A low-flow showerhead can reduce water usage by up to 50%, which means lower water bills for homeowners.

2.     Fix leaks

A leaky tap or a running toilet can waste a lot of water over time. In fact, a dripping tap can waste up to 20 litres of water a day! Homeowners should fix leaks as soon as they notice them. This not only saves water but also prevents water damage to your property.

3.     Use a rainwater harvesting system

New Zealand has plenty of rainfall throughout the year, so it makes sense to capture and store rainwater for later use. Installing a rainwater harvesting system can provide homeowners with a reliable and sustainable source of water for their gardens and other outdoor uses. Rainwater can also be used for flushing toilets and washing clothes, which can significantly reduce water consumption.

4.     Reduce lawn irrigation

Watering the lawn is one of the most water-intensive activities in any household. Homeowners can save water by reducing lawn irrigation, especially during the summer months when water is in high demand. Watering the lawn early in the morning or late in the evening can also reduce evaporation and ensure that the water reaches the roots of the grass.

5.     Be mindful of water usage in the kitchen and laundry

The kitchen and laundry are two areas of the home where water consumption can be high. Homeowners can reduce water usage in these areas by being mindful of their water usage habits. For example, running the dishwasher and washing machine only when they are full can save water. Using a bowl of water to wash vegetables instead of running the tap can also reduce water consumption. Additionally, using a front-loading washing machine can save water compared to a top-loading machine.

6.     Install a dual-flush toilet

Toilets are responsible for a significant portion of water usage in the home. Installing a dual-flush toilet can significantly reduce water consumption. Dual-flush toilets have two buttons – one for a full flush and one for a half flush. This means that homeowners can choose to use less water for liquid waste, which can save up to 67% water compared to a traditional toilet.

7.     Use a broom instead of a hose to clean outdoor areas

Using a hose to clean outdoor areas such as patios, driveways, and sidewalks can waste a lot of water. Homeowners can save water by using a broom instead of a hose to clean these areas. Sweeping the area first can also reduce the amount of water needed to clean the surface.

8.     Install a water meter

Installing a water meter can help homeowners keep track of their water consumption and identify any areas where they can save water. A water meter can also help homeowners detect leaks and reduce their water bills.

9.     Use mulch in the garden

Mulching is an effective way to reduce water consumption in the garden. Mulch helps to retain moisture in the soil, which means less water is needed for irrigation. Homeowners can use a variety of materials for mulch, such as wood chips, leaves, grass clippings, or even newspaper.

10. Use a bucket to catch cold water

When waiting for the water to heat up in the shower or sink, homeowners can use a bucket to catch the cold water. This water can then be used for other purposes such as watering plants, flushing the toilet, or even washing the car. This simple habit can save a lot of water over time. If you are running the water to wash dishes, catch the water in the kettle or water filter before it runs hot.

11. Don't overwater plants

Overwatering plants is a common mistake that many homeowners make. This not only wastes water but can also harm the plants. Homeowners should only water plants when they need it and avoid watering them during the hottest part of the day when water evaporates quickly.

12. Use native plants in the garden

Using native plants in the garden can help to reduce water consumption. Native plants are adapted to the local climate and require less water than exotic plants. They also provide important habitats for native wildlife and help to preserve the local ecosystem.

13. Use a compost bin

Using a compost bin can help to reduce water consumption in the garden. Composting recycles organic matter and helps to improve soil health, which means less water is needed for irrigation. Composting also reduces the amount of waste that ends up in landfill, which is good for the environment.

14. Take shorter showers

Taking shorter showers is a simple but effective way to save water. A five-minute shower uses around 50 litres of water, while a 10-minute shower can use up to 100 litres. Homeowners can reduce water consumption by taking shorter showers and turning off the water while lathering up.

15. Use a high-efficiency washing machine

High-efficiency washing machines use less water than traditional machines and are better for the environment. They also use less energy, which means lower electricity bills for homeowners. When buying a new washing machine, homeowners should look for one with a high energy and water efficiency rating.


In conclusion, there are many practical water-saving tips for homeowners in New Zealand. Installing low-flow showerheads and faucets, fixing leaks, using a rainwater harvesting system, reducing lawn irrigation, and being mindful of water usage in the kitchen and laundry are just some of the ways that homeowners can reduce water consumption and save money on their water bills. By implementing these measures, homeowners can contribute to the conservation of this precious resource and help to ensure that there is enough water for everyone.
