Stevenson

What Stevenson does

Stevenson is a New Zealand quarrying and concrete materials operator headquartered at Drury (41 Bill Stevenson Drive), operating as a wholly-owned division of Fulton Hogan since the 2018 acquisition of Stevenson Construction Materials. The company runs 14 sites spanning the Auckland, Waikato, and Bay of Plenty regions, producing aggregates (roading, drainage, sand, concrete aggregate), ready-mix concrete, precast products and IANZ-accredited laboratory testing services. Its flagship Drury Quarry produces approximately 3 million tonnes of aggregate annually and supplies over 25% of Auckland's aggregate requirements, with in excess of 150 years of extractable resource still available at that site alone. Other operational assets include the Clevedon greenfield quarry (positioned for 50 years of Auckland supply), Waingaro (hardrock greywacke, ~10 years remaining plus extension proposed), Tauhei (~25 years), Tūākau (sand and pumice), Poplar Lane (~50 years), and Bell Road (sand plant). The company also holds a decades-long IANZ-accredited testing laboratory at Drury, providing independent quality assurance services to civil engineering customers.

Stevenson's business model is sales-led with regional account managers covering Waikato, Bay of Plenty and Auckland, dispatch teams accepting orders by phone for aggregates (09 984 8571) and concrete (0800 800 611), and a transport fleet operating from a Drury depot that delivers aggregate, sand and fill across the upper North Island. Revenue is generated primarily through one-time sales of aggregate and concrete to construction contractors, infrastructure projects and residential builders, supplemented by professional services fees from IANZ-accredited independent testing. Pricing is quote-based with no publicly disclosed standard rates. Customer segments include government infrastructure projects (Watercare, Auckland Transport, KiwiRail, Transpower), commercial construction firms, and residential builders/developers, with named past contract wins including 225,000 tonnes of quarry overburden to Watercare's Puketutu Island biosolids project, precast modular speed tables for Auckland Transport, basecourses for the Tauranga Eastern Link, and rail ballast for KiwiRail. Specialty product brands include Hydrovia® permeable concrete, ECOPERLITE™ low-carbon concrete (carbon footprint under 100 kg per tonne vs 500-800 kg for conventional cement), and the iStrada paperless ticketing and concrete delivery management system.

Operational differentiation comes from long-life reserves, branded specialty products, and continuous improvement programmes. A 2025 Atomised Mist dust suppression system installed at Drury reduces dust by 90% and water usage by 97%. The company's safety record earned it the 2024 Concrete NZ Health, Safety and Wellbeing Award (injuries reduced from 21 in 2022 to 3 in 2024) and the WorkSafe Chief Inspector Safety Leadership Award, and research with the University of Newcastle on science-backed safety bunds was published in the Journal of Rock Mechanics and Geotechnical Engineering. The customer base, particularly government infrastructure contracts, combined with projected 70% growth in Auckland's construction sector over the next decade, provides a stable expansion backdrop.

Regional players

• Roads & Civil Contracting: NZ civil contractor operating in the Bay of Plenty and upper North Island with own quarrying capabilities. Overlaps with Stevenson's regional customer base of roading and infrastructure customers.
• Perry Aggregates: Waikato-based aggregate producer formerly owning Waingaro Quarry (acquired by Fulton Hogan/Stevenson in 2016). Comparable in aggregates product offering but with a smaller regional footprint in the same upper North Island market.
• HEB Construction: NZ civil construction contractor with integrated quarrying operations producing aggregates and roading materials. Comparable business model combining civil contracting with quarry supply, operating primarily in different regions from Stevenson.
• Isaac Construction: South Island NZ civil contractor and quarry operator. Operates aggregates and concrete operations in the Canterbury/Christchurch region, comparable in product mix but not directly competing in Stevenson's North Island territory.

Broad incumbents

• Holcim New Zealand: Global cement, aggregate and concrete major operating in New Zealand. Acquired four Stevenson ready-mix sites plus perlite facility, demonstrating both competitive overlap and customer/supplier adjacency in the NZ market.
• Golden Bay Cement: New Zealand's only domestic cement manufacturer, part of Fletcher Building. Provides upstream cement supply relevant to Stevenson's ready-mix and competes more broadly in the NZ construction materials value chain.

Direct peers

• Firth Concrete: Major New Zealand ready-mix and concrete products supplier, part of Fletcher Building. Directly competes with Stevenson's concrete operations and supplies similar commercial, infrastructure, and residential segments across the North Island.
• Winstone Aggregates: New Zealand's largest aggregates producer, operating quarries across the upper North Island including Hunua. Directly competes with Stevenson in crushed stone, sand and gravel, and is a fellow participant in the 2023-2024 safety bund research program alongside Stevenson.
• Allied Concrete: New Zealand ready-mix concrete producer with plants across the North Island. Competes directly with Stevenson's concrete operations and similarly serves commercial, residential, and infrastructure customers.
• Kaipara Quarries Group: Major Auckland-based quarry operator. Joins Stevenson, Fulton Hogan, Winstone Aggregates and The University of Newcastle in the safety bund research project and competes in the Auckland aggregates market.
