Winter tips for a changing climate

Winter has a way of reminding us what matters most: warm homes, dry spaces and smart ways to stay comfortable. If you’re feeling some climate blues, don’t despair. Whether you're trying to keep your home warm, reduce your power bill or make the most of winter, there are solutions to the season, from low-cost easy fixes to projects that might take a little more planning.

Here are ways to get warm, stay dry, and get ahead of the climate curve this winter.

Mānawatia a Matariki

The reason for the season

Instead of hiding from winter, how about getting to know it? Matariki marks the end of harvest time, when whānau come together to share food and stories, remember loved ones and look to the stars for evidence of the weather and climate to come.

So, gather up the family, rug up in your warmest woollies and celebrate our new year at one of the many Matariki ki te Manawa events across Tāmaki. From reflective light installations to immersive art to live music, there are heaps of opportunities to connect and have more kōrero with nature so that nature can guide us.

Let your home breathe

Keep the warmth in and the damp out

Small changes can make a big difference, only take a few minutes and cost less than you might think.

  • Pick up some weather strips from your local hardware store and seal your window frames to keep warm air in and cold out. If you’re renting, they’re easy to remove without causing damage.
  • Throw open your windows for a few minutes every morning. Drying out wet windows is a major move against mould.
  • Pop a ‘door snake’ under every door, even the inside ones, to stop chilly air sneaking in. You can even make your own by stuffing the legs of old jeans with rags.

Power moves

Stay warm, spend less

A few simple changes can help keep your home warm and save on your bills.

  • Swap old light bulbs for LEDs. Shave around 10% off your power bill.
  • Set your heat pump (if you have one) between 18 and 21°C and leave it on for longer (rather than short bursts).
  • Keep your shower shorter. Reducing to 4 minutes could save $60 each month.
  • Dry your clothes on the line, or inside near an open window to knock up to $300 off your yearly power bill.

We’re making power moves too. Auckland Council is switching off gas boilers and powering up solar rooftops, saving heaps for Auckland and doing our bit to reduce emissions.

Rain it in

Free water for your garden

Before water came at the turn of a tap, people collected rainwater to drink, cook and grow kai. Today, a rainwater tank can help you store water from your roof to use in the garden, toilets or washing machine.

It can help lower your water bill, provide a backup water supply during dry spells, and reduce pressure on stormwater drains during heavy rain. With El Niño expected to bring drier than normal conditions this year, storing rainwater now can help you prepare for the months ahead.

Turn your brain to the drain

Keep the water moving

When it rains, it pours, and when drains are blocked, water starts looking for somewhere else to go. That can mean flooded roads, footpaths and driveways, and more water flowing towards homes.

Keeping our water moving is a team effort. Auckland Council has crews out before and after big rains, clearing high-risk drains to help reduce flood risk. Watercare’s Central Interceptor is helping reduce overflows and protect our waterways.

You can do your part too. Clear the grate outside your home, rake leaves off the footpath and, if you can, say kia ora to your neighbour who might need a hand.

Don’t sit on the fence, fix it!

Help water find its way

During Auckland's January 2023 floods, water became trapped behind solid fences, causing many to collapse and sending surges of water through neighborhoods. If you have a solid fence, consider making changes that help water flow underneath or through, rather than building up behind it. 

Start by checking Flood Viewer to see if your property is in or near a flood zone. If it is, and you have a solid fence, this tip could make a difference.  

For timber fences, create a gap underneath by removing the bottom horizontal palings or cutting the vertical palings so they’re not touching the ground. For concrete, steel or rock fences, add openings by drilling holes at the bottom or replacing sections with a more open design.

Beat the SADs

Lift your mood with a rain garden

Feeling a bit SAD (short for seasonal affective disorder), or just over the winter blues? A rain garden might help boost your mood. Turn a boggy corner of your garden into a mini oasis for birds, native plants, bees and you. Swap grass or concrete pavers for soil, gravel and water-loving plants like harakeke, carex and toetoe. Add flowering natives and glow-up the grey gloom.

Across Tāmaki Makaurau, Auckland Council is investing in rain gardens, wetlands and other green spaces to help communities manage stormwater naturally. From the tree lined streets of Te Hā Noa on Victoria Street to new wetland at AF Thomas Park to a flood resilience project in Rānui. Better drainage, more wildlife, and more reason to get outside on a winter day? That's something to feel better about.

Be a rain detective

A rainy day kid activity

The next time it rains, wrangle the kids into their gumboots and take everyone on an adventure. Follow the water as it flows from your roof, down the driveway and along the street. Where does it disappear? Can you find the drain, stream or creek it joins?

Draw your own map, figuring out a way to follow the stream as far as the sea. Explore your local overland flow path using Flood Viewer (sometimes these are actually roads!).

Find out how water used to flow in your neighbourhood (top tip: google image search “early flood + your suburb”). Water has a long memory and following its path is a great way to understand how it might behave in the future.

From flood risk to resilience

Help nature protect your neighbourhood

Ka ora te wai, ka ora te whenua, ka ora ngā tāngata
If the water is healthy, the land is healthy, the people are healthy

If flooding in your area worries you, you’re not alone. By connecting with nature and taking action in your community, you can support your wellbeing and make a meaningful difference.

Across Tāmaki Makaurau, marae and community groups are restoring streams, planting native species and clearing waterways to help slow floodwater and improve the health of local rivers.

The Ōtara Waterways Flood Resilience Project is one example where volunteers, mana whenua and Council are working together to reduce flood risk and restore the mauri of the creek. Across the rohe, through Te Ara Urutau, Auckland Council is supporting more locally led projects that are helping communities adapt together.

Embrace a watery future

Get to know your local waterway

The human body is 60% water. Our planet is about 70%. As the climate warms, the atmosphere holds more moisture, bringing heavier downpours. Water has always shaped Tāmaki Makaurau, and it will shape our future too.

Auckland’s Water Strategy, developed with mana whenua, is helping our city rethink the way we manage, use and value water. It brings together mātauranga Māori and science to support healthier rivers, streams, harbours and wetlands for generations to come.

This winter, spend some time by your local stream, harbour or beach. The more we understand our waterways, the better we can care for them.
