As temperatures drop and damp weather sets in, Kiwi homes are put to the test. Cold spots, condensation, and rising power bills are all too common in New Zealand’s winter months—especially in older or poorly insulated homes. The good news? With the right approach to insulation and heating, you can stay warm, dry, and energy efficient all winter long.

This guide breaks down the essential steps to winter-proof your home, improve comfort, and reduce unnecessary costs.

Start With the Basics: Insulation

Insulation is your first line of defence against winter cold. It slows heat transfer, helping your home retain warmth and reduce the need for constant heating.

Here’s what to check:

  • Ceiling insulation: Heat rises, and up to 40 percent of your home’s warmth can be lost through the roof. If your ceiling insulation is old, thin, or patchy, it’s time for an upgrade.
  • Underfloor insulation: Especially important in timber homes with ventilated subfloors. Proper insulation prevents cold air from rising through floorboards and keeps moisture at bay.
  • Wall insulation: Often overlooked, but key for maintaining stable indoor temperatures. Retrofitting insulation in accessible wall cavities can make a noticeable difference.
  • Ground moisture barrier: If your home has an enclosed subfloor, installing a polythene sheet over the soil can stop moisture from rising, reducing dampness and supporting better indoor air quality.

Even if your home already has insulation, it may not meet current standards or be performing efficiently. An assessment can identify gaps and opportunities to improve.

Add Effective Heating

A well-insulated home needs far less heating—but you still need a system that’s reliable and efficient during the coldest months. The Healthy Homes Standards require a fixed heating device in the main living area capable of heating the space to at least 18°C. But beyond compliance, your comfort depends on choosing the right solution for your space.

Recommended options include:

  • Heat pumps: The most efficient choice for most New Zealand homes. They provide fast, clean heat with low running costs, and many include dehumidifying features to help manage condensation.
  • Panel heaters: A compact and affordable solution for small spaces or bedrooms. Some models are wall-mounted and thermostat-controlled for consistent heating.
  • Flued gas heaters and wood burners: Less common, but suitable in specific cases where electricity supply or aesthetics call for alternatives.

Avoid portable unflued gas heaters, which can increase indoor humidity and pose safety risks.

Manage Moisture and Ventilation

Winter often brings increased condensation on windows and walls. If left unaddressed, this can lead to mould, mildew, and structural damage.

To reduce excess moisture:

  • Ensure your kitchen and bathroom have working extractor fans that vent to the outside
  • Use a ground moisture barrier in homes with enclosed subfloors
  • Open windows during the day to allow cross-ventilation when weather permits
  • Consider using a dehumidifier in particularly damp areas

Good ventilation supports your heating and insulation by keeping the indoor environment drier and healthier.

Know Your Compliance Obligations

If you’re a landlord, Healthy Homes Standards require that insulation, heating, ventilation, moisture control, and draught-stopping are all up to code. Non-compliance can result in penalties—and it may also impact tenant wellbeing and retention.
