Sunergise to buy Infratec in New Zealand solar deal
Tue, 27th Oct 2026 (Today)
Sunergise has agreed to acquire Infratec from WEL Networks, creating one of New Zealand's largest solar businesses.
The deal combines Sunergise's commercial solar portfolio with Infratec's utility-scale solar and battery energy storage work. The combined business will serve commercial, industrial and utility-scale customers in New Zealand and the Pacific, spanning project development, engineering, financing, operations and maintenance.
WEL Networks is selling Infratec as it shifts its focus to network and infrastructure operations. Existing contracts, client relationships and service commitments at both businesses will continue unchanged.
Sunergise has completed more than 200 commercial solar installations and says it has installed more than 50 megawatts of solar capacity across New Zealand and the Pacific. Its projects include a 5.3 MW rooftop system at Fisher & Paykel Healthcare and a 2.3 MW installation at Mānawa Bay.
Wellington-based Infratec specialises in the development, design, engineering, procurement and construction of solar photovoltaic and battery storage systems. It has built 194 MW of solar PV and deployed 49 MWh of battery storage.
Scale and reach
Infratec has delivered projects for infrastructure clients including Transpower and Alpine Energy. Recent work includes the Te Herenga o Te Rā solar farm in the Bay of Plenty and the New Plymouth Airport Solar project.
The acquisition also expands Sunergise's presence in Pacific markets. The group already operates in the region through Fiji-based Clay Energy, acquired from Todd's Pacific solar operations earlier in 2026.
Sunergise and Infratec have worked together before in the Pacific. From 2020, they delivered five renewable energy plants across Nauru, the Federated States of Micronesia, the Marshall Islands and Palau.
Those projects included what the companies described as New Zealand's first renewable energy project in Micronesia. The programme received the National Energy Globe Award for Nauru and was also recognised by the Sustainable Energy Association of New Zealand with its Best Grid-Connected System award.
Paul Makumbe, Chief Executive Officer of Sunergise, said the deal would strengthen the company's ability to meet growing demand across the market.
"New Zealand's and Pacific's renewable energy transition requires investment at every scale: commercial rooftops and large-scale generation," Makumbe said.
"Together we can meet that demand. Our offerings are fully complementary, and we now have the skills, experience and capacity to deliver the full spectrum of services to help expedite that much-needed transition."
Makumbe also highlighted Infratec's record in larger projects and battery storage.
"Infratec has a technical record that speaks for itself: 194 megawatts built, 49 megawatt-hours of battery storage deployed, and a client list that includes some of New Zealand's largest infrastructure operators," he said.
"Combined with Sunergise's commercial solar depth and Pacific reach, this is a genuinely compelling offer for clients who need more than a single-service provider."
