CEO
Accumen is a trusted name in New Zealand’s construction and building materials landscape, with a market presence spanning over 30 years. We have earned a reputation for reliability, innovation, and a “can-do” approach that consistently delivers value across residential, commercial, and specialist construction sectors.
We are commented to local manufacturing, exclusive distribution, and technical specification, offering products and services that are both industry-proven and forward-thinking. Our adaptability and responsiveness — from product development to compliance support — set us apart as more than just a supplier: we’re a solutions partner.
Trusted by Industry Leaders
Our enduring partnerships with leading national construction and materials companies reflect our long-standing reliability and the consistent performance of our solutions. These collaborations underpin a wide range of successful projects, from architecturally significant homes to civic infrastructure and commercial developments
As the exclusive distributor for a number of globally recognised insulation brands, Accumen serves as a key conduit for bringing high-performance materials to the New Zealand market. Our offering includes innovative solutions like Hot Edge, a thermal enveloping system widely adopted in slab construction, developed through our successful partnership with Firth Industries.
Serving the Full Construction Spectrum
We support a diverse client base — from homeowners to builders, architects, engineers, and specifiers. Our team offers practical advice, specification support, and product recommendations tailored to the specific needs of each project, whether it’s a one-off detail or a full-scale development.
Innovation, Development, and Local Focus
At Accumen, we invest heavily in product development, technical testing, and customised solutions. We convert and adapt global systems for the New Zealand context, often prototyping and refining ideas in collaboration with our industry partners. Our growing local manufacturing capabilities enhance our flexibility and responsiveness, allowing us to deliver tailored, high-performance solutions at speed and scale.
Our Team
The strength of Accumen lies in our team — a dedicated group of professionals who bring deep industry knowledge, creativity, and an unwavering commitment to quality. From customer service and logistics to design and technical support, we work together to ensure outstanding results and long-term value.

As the construction landscape evolves, so does Accumen. Our commitment to innovation, technical integrity, and trusted partnerships positions us to lead in delivering smarter, more efficient building solutions.
