What InterGroup does
InterGroup is a New Zealand-headquartered integrated infrastructure and industrial services provider, founded in 1978 and family-owned, that delivers more than 70 specialised services across six categories: infrastructure services, industrial cleaning and maintenance, protective coatings and surface preparation, environmental services, waste disposal, and facility maintenance. From 16 branches across New Zealand, the company deploys 576 employees and a 481-vehicle specialised fleet — including New Zealand's largest hydro-excavation fleet and 11 full-EV heavy vehicles — in support of city and district councils, oil and gas operators, energy producers, ports, food and beverage processors, and construction contractors. Operational leadership is held by CEO Byron Hill, son of founder Alan Hill, who transitioned into the role in 2024 after more than two decades inside the business.
Service delivery is built around a technology stack that enables remote or no-man-entry execution of hazardous work. Core systems include the Gerotto Lombrico robotic tank cleaner (ATEX-rated for Zone 0 explosive atmospheres), the Flyability Elios 3 confined space drone with 4K camera and 3D LiDAR, the StoneAge Sentinel AutoBox 3L automated tube and pipe cleaner (rated up to 3,000 bar), the Aqua Cutter 710V robotic hydro demolition robot (15,000–55,000 psi), and a suite of robotic blast machines (HydroCat, Verti Drive, SpiderJet). Data from the Elios 3 is processed via Faro for survey-grade 3D modelling, while the multi-sensor laser profiler (sonar, laser, CCTV) feeds the IKAS pipeline assessment platform for compliance with the New Zealand Gravity Pipe Inspection Manual. The Auckland-based Resource Recovery Facility processes approximately 60,000 tonnes of wet waste per annum, achieves 64% landfill diversion, and recycles up to 90% of process water. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, maintains 100% Tōtika and SiteWise Gold safety ratings, and holds a Basel Convention permit authorising PFAS export.
InterGroup makes money through a mix of long-term government service contracts and project-based industrial engagements. Recurring revenue is anchored by multi-council relationships such as Hutt City Council's street and city cleaning (continuous since 1999), Auckland Council Healthy Waters (180,000 catchpits inspected annually), Tauranga City Council CBD cleansing, and Wellington City Council's CBD cleansing contract commenced in July 2025. Project-based work spans shutdowns, tank and heat-exchanger cleaning, pipeline pigging, catalyst handling, protective coatings, and hazardous waste collection and disposal — including geothermal sludge removal at the Ohaaki and Ngawha power stations, catalyst handling for Ballance Agri-Nutrients, and large-scale fire remediation and protective coatings at the New Zealand International Convention Centre (NZICC). Pricing is quoted on a project-by-project basis; the company markets through its website, LinkedIn, case studies, industry events, and earned media, including the 2024 Water New Zealand Innovation Award for the Resource Recovery Facility.
