How to save money on your power bill this coming winter in Auckland

With electricity prices in New Zealand projected to rise due to infrastructure upgrades and increased operational costs, it’s a good time to take action. Whether in Auckland or elsewhere in New Zealand, being smart about how you use energy this winter can make a noticeable difference. This guide breaks down practical ways to cut costs — from easy habits to home upgrades that pay off over time.

Understanding the 2025 Power Price Increases

From April 1, 2025, electricity prices in New Zealand are set to rise due to increased infrastructure investments and regulatory changes. Households can expect their power bills to increase by about $10 to $25 per month, depending on their region and usage patterns. In some areas, such as Dunedin, the increase could be as high as 13.6%.

Passive Strategies to Reduce Power Consumption

These things don’t require much money or effort, but make a difference.

1. Insulate Your Home

• Proper insulation can significantly reduce heat loss, keep your home warmer, and reduce heating needs. If you haven’t already, consider insulating your ceiling, walls, and floors.​
  
• Open windows for at least 30 minutes a day. A dryer home is easier to heat. If you already have extraction fans installed, use them when cooking, showering, or using a dryer.

2. Seal Drafts

• Check for drafts around windows and doors. Using weather stripping or draft stoppers can prevent cold air from entering and warm air from escaping.​

3. Utilize Natural Sunlight

• During the day, open curtains and blinds to let sunlight naturally warm your home. Close them at night to retain the heat.​

4. Use Rugs and Carpets

• Floor coverings can add an extra layer of insulation, keeping your feet warm and reducing the need to turn up the heater.

5. Block Off Unused Rooms

• Shut the doors to rooms you aren’t using. It helps your heater work more efficiently.

6. Layer Up

• Wear warm clothing inside. It sounds simple, but it can delay needing to turn on the heater.

Smarter and Active Strategies to Reduce Power Consumption 

These are tips to use electricity more efficiently and reduce waste.
​
1. Heat Smarter

• Set your heat pump or heater to 18-20°C. That’s a comfortable temp without wasting energy.
• Use a timer so it turns on before you get home, and off while you sleep.
• Avoid using multiple heaters in different rooms. Heat only where needed.

2. Hot Water (electric)

• Showers use a lot of hot water. Try to keep showers under 10 minutes.
•  Set your hot water cylinder to 60°C max. That’s hot enough for hygiene and safe use.

3. Kitchen Use 

• Only boil as much water as you need in the kettle, or put boiled water in a vacuum jug.
• Use lids when cooking to reduce cooking time for non-gas cooktops.

4. Laundry Tips

• Wash clothes in cold water. Most detergents work just as well.
• Hang clothes to dry in a well-ventilated place when possible instead of using the dryer.

5. Turn Off Unused Devices

• Switch off appliances at the wall when not in use. TVs, game consoles, microwaves and chargers still use power when on standby.

​Easy Home Upgrades That Save Money
​
If you can afford to make small upgrades, these can lead to big savings over time.

1. LED Lighting

• Switch to LED bulbs. They use up to 85% less electricity and last years longer than normal bulbs.

2. Insulation

• Insulating your ceiling and underfloor can cut heat loss by up to 50%. Some households may qualify for free or subsidised insulation.

3. Extraction

• Install a rangehood above your cooktop to extract damp air created from cooking
• Install bathroom extraction fans to ventilate bathrooms while showering. Installing a run-on timer will automatically turn the fan off after, say, 10 minutes.
• Duct your dryer to the outside. The dryer will run more efficiently, and your home won’t fill with damp air
• Install a home ventilation system that can bring warm, dry air from your roof space down into your home, replacing stale air within the home

4. Heat Pumps

• Heat pumps are one of the most efficient ways to heat a home. They use less power and give more heat compared to plug-in heaters.

5. Smart Timers & Thermostats

• These let you control when your heating turns on and off, so you’re not wasting power when you’re out or asleep.
