RENTING

We all want to be able to live in secure, healthy and resilient housing, despite climate change. To do this, we need suitable housing that protects us from the heat, cold and storms. Energy efficient housing also keeps the bills down and health costs low.

Check Auckland Flood Viewer first!

This free tool helps you check if an Auckland rental property could flood in a big storm, how it might be affected and how to stay safe. You can also use Flood Viewer to check if your current rental is in a flood hazard zone.

Understanding the flood risk of the property you're renting and making a plan to protect your whanau and belongings is important.

This information is also now available as a "layer" in the maps on TradeMe property listings.

We know it can be a bit confusing, so here’s a simple breakdown of what each layer means.

1. Floodplains

This layer shows areas that could get flooded from things like overflowing rivers or streams during a big storm. The modelling for this is based on a storm that has a 1% chance of happening in any given year (a "1-in-100-year" event). It also takes into account how future development and climate change might affect these areas.

What it means for you: If a property is in a floodplain, it's at a higher risk of getting flooded during a major storm.

2. Flood Prone Areas

These are areas where water can collect and sit during heavy rain because of the natural shape of the land. Think of a dip in the ground that acts like a bowl, trapping water when the stormwater drains are overwhelmed.

What it means for you: If a property is in a flood prone area there’s a chance that water could pool, even if there isn't a stream nearby.

3. Overland Flow Paths

This layer shows the natural route water takes when it flows across the land during a major downpour. These are like temporary streams that form when the regular stormwater pipes can't handle all the rain.

What it means for you: If a property is on or near an overland flow path, it might be in the path of moving water during a storm, which could cause damage or block access.

Reminder:

This is a guide, not a guarantee. Flood risks can change over time.

Insulation

Check if the property is insulated in the ceiling and under the floor. This should be noted in the Healthy Homes compliance statement. Good insulation helps keep heat in during winter and blocks excess heat in summer, meaning you’ll use less power for heating and cooling, and save on your energy bills.

Double glazing

This makes a big difference for heat and noise, as well as moisture and mould. If the windows are double-glazed, you’ll definitely feel the benefits.

Aircon/Heat pump

If there’s no AC and the windows aren’t well shaded or able to open widely (or at all), be careful. Retrofitting AC in a rental is expensive and not always possible. If there is AC, check which rooms it actually cools/heats.

Signs of damp, water damage or mould

Check for ground sheets under the house as well as extractor fans. These can help reduce moisture build up.

Window placement and cross-breeze

Can you get airflow by opening opposing windows? A good cross-breeze can mean the difference between needing AC or not in warm weather, and is a good way to get rid of extra moisture in winter.

External shading or eaves

Do the windows have anything over them on the outside to block direct sun, or is there a shade sail? External shading can stop summer heat in its tracks and save you money.

Fixtures and appliances

Look for energy-efficient lights (like LEDs), heat pumps and appliances with good energy ratings. Older or cheap appliances can suck up power and overheat your space. Full-length, lined curtains are also great at keeping in heat in winter and reducing overheating in summer.

Trees and green space

Townhouses and apartments are often cooler when they have shady street trees and well-established plantings.

Keeping cool upstairs

The things that can keep you cool in summer matter even more if you’re looking at an apartment that’s high up or if you're planning to sleep in a second or third-floor bedroom. Heat rises, and upstairs rooms often get the worst of it, so good ventilation and protection from the sun become extra important.

Landlords are responsible for equipping your property so you can maintain it within reasonable temperature limits (not too hot in summer, not too cold in winter)
Homes must have adequate drainage so stormwater can easily move through
Landlords need to make sure your home has no unreasonable draughts and that there are extractor fans in the kitchen and bathroom. Your home also needs to have ceiling and underfloor insulation where practical.

After storms or floods

Landlords are responsible for repairing damage caused by flooding and storms, including drying out the property (this includes the cost of electricity)
If your rental property is damaged but you can still live in it, your rent should be reduced while the property is being fixed
If your rental property has been destroyed or seriously damaged, and you want to leave, you need to give your landlord two days’ notice. If the landlord wants their uninhabitable property vacated, they need to give you seven days’ notice.

But even with small changes, you can make your home more comfortable, energy-efficient and ready for any weather.

Stay warm and dry in winter

Use full length, lined curtains to stop heat escaping through windows.

Seal gaps with removable draft stoppers or weather strips (they’re cheap and leave no damage).

Open windows regularly to remove condensation.

Use moisture absorbers (like baking soda or charcoal) in damp areas.

Layer rugs over hard floors to keep warmth in.

Stay cool in summer

Use light curtains or blinds to block heat during the day and open them at night to let cooler air in.

Create cross-breezes by opening windows on opposite sides of your home, or opening a window on both the ground and upper floor. Pedestal fans are also a simple, low cost and effective way to cool.

Use fans smartly – a bowl of ice in front of a fan is like do-it-yourself air conditioning

Check if you can install a shade sail

Switch to LED bulbs – they use less energy and last ages.
Set your heat pump at 20-21 degrees.
Use a low-flow showerhead or consider shorter showers. It will save you money on energy and water.
Run washing machines in cold water and only when full.
Think about moving to a “time of use” electricity contract (some provide free energy on the weekend or cheaper energy at night).
