Creating Warmer, Healthier Southland Homes Since 2004
At Awarua Synergy, we’re passionate about making homes across Southland warmer, drier, and more energy efficient. Since 2004, 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 practical energy efficient solutions including insulation upgrades, blown-in wall insulation, heat pump supply and installation, ventilation systems, double glazing, LED lighting, and hot water systems, providing expert advice tailored to the needs of Southland homes.
Our experienced local team understands the challenges of Southland’s climate and works with homeowners, landlords, community organisations and businesses to deliver solutions that improve comfort, reduce power bills and support healthier living. From older villas and rental properties to schools, community buildings and commercial spaces, we take a practical, honest approach tailored to each property and customer.
At Awarua Synergy, we believe creating a warm, energy-efficient home is about more than just products. It’s about helping people make informed decisions that improve everyday comfort and long-term wellbeing.
That’s why we take a whole-of-home approach. We look at insulation, heating, ventilation, moisture, lighting, and energy use together to find practical solutions that genuinely work for Southland homes.
We help eligible homeowners access funding support such as Warmer Kiwi Homes subsidies and other programmes designed to reduce the cost of home energy upgrades. In fact, we are proud to offer access to the largest range of grants and subsidies across the region, helping you make those vital home improvements when it matters.
Our team provides straightforward advice and guidance throughout the process, helping make energy improvements more accessible and achievable.
At Awarua Synergy we are able to offer access to Warmer Kiwi Homes Grants, Southland Homes Trust Grants, Healthy Homes Initiative and Meridian Energy Well-Being Programme.
Proudly Southland
As a locally owned and operated company, we’re proud to support communities across Invercargill, Gore, Winton, Te Anau, Riverton, Bluff, and wider Southland.
Whether we’re upgrading insulation, improving indoor air quality, or helping families reduce energy hardship, our goal remains the same; to create warmer, healthier homes and stronger communities, one project at a time. 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.
