Warmer, Healthier Southland Homes From the Local Experts

At Awarua Synergy, we’re passionate about making homes across Southland warmer, drier, and more energy efficient. For over 20 years, we’ve been trusted by families from Invercargill to Winton, Gore, Te Anau, Riverton, Bluff, and Mataura to deliver practical solutions that improve comfort and reduce power bills.

We specialise in insulation, heating, ventilation, double glazing, LED lighting, and hot water systems, providing expert advice and installation tailored to the needs of Southland homes. Whether you need insulation, a heat pump, a new hot water cylinder or even double glazed windows, our team is here to help.

More Than Just Products

We’re not only about installations — we’re about making a real difference. Our free home assessments are the first step in helping families find the right mix of solutions. We also partner with programmes like Warmer Kiwi Homes and the Southland Warm Homes Trust to help eligible families access subsidies for insulation and heating. By doing so, we make warm, dry, energy-efficient living a reality for more Kiwis.

Our Commitment to Southland

Every project we take on reflects our commitment to sustainability, community, and innovation. We only recommend products we trust, working with leading brands like Mitsubishi & Daikin for heat pumps, Terra Lana and Pink Batts for Insulation, Nulook for double glazing, and other quality New Zealand suppliers of ventilation, LED lighting, and heat pump hot water systems.

At Awarua Synergy, we don’t just improve homes — we help build a brighter, greener future for generations to come. Together, we can transform your home into a space that’s healthier, cosier, and more energy efficient.

More about Awarua Synergy

The Deep South is a challenging place to live — cold weather, damp conditions, and long winters put real pressure on homes, farms, and businesses. What works for Auckland won’t always work here. That’s where Awarua Synergy comes in.

Our origins go back to the Bluff Healthy Homes project, which insulated more than half the homes in New Zealand’s southernmost town. The project didn’t just install insulation — it also provided one-on-one education to help families understand energy efficiency, eco-friendly heating, and sustainable living. Its success led us to expand across Southland, carrying forward the same vision of healthier homes and lower power bills for every household.

Today, we’re proud to be leading suppliers and installers of cost-effective, energy-efficient solutions across Southland. From Invercargill to Te Anau, Gore to Bluff, we bring warmth, healthy air, LED lighting, and modern heating technology to the people of the Deep South — helping them take power over their power bills.

What our customers have to say...

I just want to pass on to you my appreciation for arranging the installation of my new heat pump. What a difference. Fantastic! But very very importantly, I want you to pass on to management my absolute thrill at the service provided by the three young men who installed the product. Each of them showed me great respect and kindness. I was amazed at their efficiency and competency. Each young man had a ready smile (the two installers and your electrician) and a willingness to assist in any way. I was a former managing director of a medium sized company and our motto was: ‘ do what you say you will do’. Awarua Synergy has done just that - thanks to you and your three young men.
