What Atlas Concrete does

Atlas Concrete is a privately held, family-owned construction materials supplier headquartered in Takapuna, Auckland, New Zealand, founded in 1940 by Melville 'Bunny' Collie and now led by his son Graham Collie. The company is vertically integrated across the construction materials supply chain, operating readymix concrete plants, three quarries (including Hukatere at Brynderwyn), sand dredging and barging from the Kaipara Harbour, precast concrete manufacturing at Silverdale, three concrete recycling facilities, and twelve branches across Auckland and Northland. Its product portfolio spans standard, decorative, coloured, permeable, and low-carbon (GreenStone LCC) ready-mix concrete; precast tilt-slab walls and structural elements; GAP, PAP, drainage aggregates, sand, sealing chip, and rip rap from company-owned quarries; and complementary building materials including base course, builder's mix, reinforcing steel, concrete blocks, bagged goods, and Cemix/Sika admixtures.

The business operates a fleet of over 120 concrete delivery trucks and approximately 70 specialist vehicles and handling equipment, including sand barges such as the Kaipara Karrier VIII, with all plant and machinery 100% company-owned. Revenue is generated predominantly through per-cubic-meter unit pricing for readymix concrete and unit/bulk pricing for quarry aggregates and bagged building materials, with quotes valid for 30 days and pricing subject to material cost fluctuations. Go-to-market is sales-led with account managers at each branch, direct phone/email ordering, an emerging click-and-collect digital channel, and field sales supporting large commercial and infrastructure projects (such as the 2013 Refining NZ Marsden Point mass pour of 2,749m³ in 16 hours, the largest single mass pour in New Zealand history).

Atlas employs over 280 people and serves a horizontally segmented customer base of foremen/project managers on commercial builds, trade builders and landscapers, and DIY homeowners. Strategic differentiators include its vertical integration, the only electric-powered plant mixers among NZ readymix producers, the most comprehensive permeable paving range in New Zealand, and certifications including NZRMCA Excellence Awards (all five Auckland plants, 2015) and SiteWise Gold (2024). The company is actively investing in a digital Delivery Management System (2025), permeable paving products (2025), and depot upgrades (Takapuna Drygoods Yard, 2026).

Scale indicators6 records

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Fulton Hogan: Fulton Hogan is a large Australasian civil contractor and materials supplier with significant aggregates, concrete and infrastructure capability in NZ. It competes with Atlas for roading, sealing chip, and large-scale infrastructure concrete supply contracts, and has broader geographic reach.
• Holcim New Zealand: Holcim NZ is a major cement, concrete and aggregates producer operating globally and in NZ. As Atlas's upstream cement supplier (via Golden Bay) and owner of ECOCycle and low-carbon product platforms, Holcim is both a critical supplier partner and a direct competitor in sustainable concrete and aggregates.
• Firth (Fletcher Concrete & Aggregates): Firth is New Zealand's largest ready-mixed concrete producer and aggregates supplier, operated by Fletcher Building. It directly competes with Atlas across the Auckland ready-mix and aggregates markets, with national scale, deeper capital and integrated cement supply via Golden Bay—making it Atlas's most significant incumbent competitor.

Regional players

• Isaac Construction: Isaac Construction is a vertically integrated NZ civil contractor with concrete, quarrying and aggregates capability primarily in the South Island and lower North Island. It is comparable to Atlas in business model (integrated quarry, concrete, civil works) but operates in a different geography.
• Stevenson Concrete (Stevenson Group): Stevenson operates ready-mix concrete and quarrying operations concentrated in the upper North Island, including Auckland. It is comparable to Atlas as a vertically integrated concrete/aggregate operator with multiple plants and a regional footprint, although with a smaller Auckland share than Atlas.

Emerging players

• Brook Seredin Concrete Placing: Brook Seredin is a specialty concrete placement and concrete services provider operating in the Auckland region, providing services complementary to Atlas's wash-off, sweeper and suction offerings and competing for adjacent contract revenue.

Direct peers

• Winstone Aggregates: Winstone Aggregates, a Fletcher Building subsidiary, is the largest aggregates and quarry operator in the upper North Island and Atlas's joint partner in Kaipara Harbour sand extraction. It competes head-on with Atlas Quarries for aggregate supply contracts across Auckland and operates a national distribution network.
• Allied Concrete: Allied Concrete is a major NZ ready-mixed concrete producer operating multiple plants in the Auckland region. It competes directly with Atlas on ready-mix volume, plant audit quality standards, and supply contracts for commercial and infrastructure projects.
• Halls Concrete: Halls Concrete is a privately owned NZ ready-mixed concrete supplier with operations across the upper North Island including Auckland, serving similar residential, commercial and rural customer segments as Atlas.

Others

• Golden Bay Cement: Golden Bay Cement (part of Holcim/Fletcher Building) is NZ's only cement manufacturer and Atlas's primary cement supplier for the GreenStone LCC line. While not a direct concrete competitor, it is a critical upstream supplier and a benchmark for low-carbon cement technology in NZ.
