Statistically, every Australian and New Zealander each consumes approximately eight tonnes of aggregate and sand each year. Every road, bridge, airport, home and major infrastructure project begins with aggregate and sand. These essential construction materials form the foundation of modern communities, transport networks and economic development.
Hardie Pacific is advancing premium diorite quarry developments within New Zealand’s North Westland. Recognised for its exceptional durability, New Zealand’s diorite is a high-performance construction aggregate used in major infrastructure, concrete manufacturing, sea wall protection and civil engineering.
With a Mohs hardness of 6.5–7.0 and a density of approximately 2.84, the resource offers outstanding strength, abrasion resistance and long-term performance, making it ideally suited to cement making, roads, bridges, ports, airports and other critical infrastructure.
Strategically located close to Westports rail and port facilities, Hardie Pacific’s quarry developments are positioned to supply New Zealand’s growing infrastructure sector while establishing a long-term source of premium construction materials.

New Zealand’s diorite deposits are among the hardest and most desirable aggregate resources, highly valued for premium aggregate and cement manufacturing.
Diorite was also used to create the stone caskets of ancient Egyptian mummies, a testament to its exceptional strength and durability.
