New Zealand Steel Limited is the owner of the Glenbrook Steel Mill, a steel mill located 40 kilometres south of Auckland, in Glenbrook, New Zealand. The mill was constructed in 1968 and began producing steel products in 1969. Currently, the mill produces 650,000 tonnes of steel a year, which is either used domestically or exported.[1][2] Over 90% of New Zealand's steel requirements are produced at Glenbrook, while the remaining volume is produced by Pacific Steel, a steel recycling facility in Ōtāhuhu, Auckland. The mill is served by the Mission Bush Branch railway line, which was formerly a branch line to Waiuku. Coal and lime trains arrive daily. Steel products are also transported daily. The mill employs 1,150 full-time staff and 200 semi-permanent contractors.
New Zealand Steel is notable due to its unique[1][2] utilization of ironsand as its ore. Because ironsand is a low grade ore with many contaminants, the mill's primary plants' operations and equipment are unusual.[2]
