JMM Insulation Team carrying an bale of insulation


Welcome to JMM Insulation, your trusted partner in insulation solutions for commercial projects, new house builds, and residential properties across the Waikato, Bay of Plenty, Coromandel, and Auckland areas.

Founded by Tom Matatahi in 2018, JMM Insulation has become a trusted stalwart in the insulation industry. Having worked in the industry since 2009, Tom decided to venture out on his own as a one-man band with a $5,000 credit card and an old van. With the invaluable support of his wife Steph, who brings her expertise in managing the books, and his commitment to hard work and customer service, JMM Insulation has grown steadily to become a reputable name in the insulation trade. 

Our journey began with a vision to make businesses and homes warmer, drier, and cozier using quality product and a quality install. Today, with a dedicated team and a fleet of resources, JMM Insulation is proud to serve a diverse clientele, including builders, construction companies, homeowners, landlords and property managers.

We’re certified IAONZ insulation installers and all work undertaken is to the Energy Efficiency Conservation Authority (EECA) standard. We follow stringent health and safety processes with site-specific hazard risk registers and SSSP for each site.
