Background

New Zealand Steel is the only fully integrated steel producer in New Zealand and was established in 1965.[1] It uses locally sourced iron sand and manufactures about 670,000 tonnes of steel slab and billet a year.[2] In May 2023, the company announced its plans to construct an electric arc furnace at a cost of NZ$300 million which will be co-funded by the New Zealand Government. The EAF is expected to become operational by 2026 and is expected to reduce NZ Steel’s Scope 1 and 2 greenhouse gas emissions by at least 45%.[3][4] The EAF will replace two of the four existing DRI kilns, one of the two melters and the oxygen steelmaking furnace (KOBM).[5]
