New Zealand Steel and Pacific Islands business comprises the Waikato North Head mine, the Glenbrook steelworks, the Pacific Steel rolling mill and the Pacific Islands businesses.
New Zealand Steel, the only fully integrated steel producer in New Zealand, uses locally-sourced iron sand and coal to manufacture about 650,000 tonnes of steel slab and billet a year at the Glenbrook steelworks south of Auckland. It produces a range of flat and long steel products for domestic and export use, and supplies all major markets including construction, manufacturing, infrastructure, packaging and agriculture.
The integrated steelmaking process starts with the Waikato North Head iron sands mine, which supplies approximately 1.2 mtpa of iron sands concentrate to the Glenbrook Steelworks, sufficient to meet its annual production requirements. The mine is operated under a long-term exclusive license with the New Zealand government.
The Glenbrook steelworks comprises ironmaking, steelmaking, a slab and billet caster, a hot and cold rolling mill, galvanising line, a paint line and a hollow sections mill. Slabs are rolled into hot and cold rolled products, which are then sold or further processed into products like hollow sections, galvanised steel, ZINCALUME® and COLORSTEEL® roofing products. Steel billets are produced at Glenbrook and sent via rail to Pacific Steel rolling mill for domestic reinforcing and wire products.
