TL;DR
Sunergise has activated New Zealand’s largest rooftop solar installation, a 5.3 MW system at Fisher & Paykel Healthcare in Auckland. The project demonstrates growing commercial solar adoption and sustainability efforts.
Sunergise has completed and officially commissioned the largest rooftop solar system in New Zealand, a 5.3 MW grid-connected array installed at Fisher & Paykel Healthcare’s Auckland campus. The project, spanning approximately 70,000 square meters across two buildings, marks a significant milestone in the country’s renewable energy sector and highlights the increasing adoption of commercial solar.
The solar installation features 8,273 solar modules and took nine months to complete. It is part of Sunergise’s SunPlus Power Purchase Agreement (PPA), allowing Fisher & Paykel Healthcare to pay only for the electricity generated without upfront capital costs. The system is projected to produce over 6,600 MWh annually, offsetting more than 486 tonnes of CO2 emissions each year.
According to Sunergise CEO Paul Makumbe, the project sets a new standard for large-scale solar in New Zealand and offers a replicable model for other major energy consumers. Fisher & Paykel Healthcare’s vice president of supply chain, facilities, and sustainability, Jonti Rhodes, emphasized that shifting to solar power is both a smart business move and a step toward sustainability, encouraging other companies to follow suit.
Implications for New Zealand’s Renewable Energy Market
This project demonstrates the feasibility and benefits of large-scale rooftop solar for commercial entities in New Zealand, potentially accelerating sector growth. It underscores a broader industry trend toward renewable energy adoption, driven by cost savings and environmental commitments. The success of this installation may influence other businesses to pursue similar projects, contributing to New Zealand’s climate goals.

Growing Adoption of Solar in New Zealand’s Commercial Sector
New Zealand’s solar capacity is rapidly expanding, with industry projections indicating a tripling from 860 MW in 2026 to over 2,100 MW by 2031. The commercial and industrial rooftop segment is a key driver of this growth, as businesses seek to reduce electricity costs and meet sustainability targets. Prior to this project, the largest rooftop system was a 2.3 MW array at Auckland Airport, installed by Sunergise.
The Auckland project represents a significant leap forward, both in scale and impact, reflecting the sector’s momentum and the increasing viability of solar as a mainstream energy source for large-scale commercial use.
“This is a landmark project for New Zealand. A 5.3 MW system on the rooftop of one of the country’s most recognised companies shows what’s possible when businesses commit to clean energy at scale.”
— Sunergise CEO Paul Makumbe
