Macleans College students explore the economics of steel
Posted on August 25, 2025
From the roar of machinery to the scale of industrial innovation, a recent field trip to New Zealand Steel’s Glenbrook Mill brought economics to life for Macleans College A Level students.
Field trips allow students to apply classroom theory to real-world situations, and this visit provided a vivid example of that connection.
The students explored how the company shapes the local economy. New Zealand Steel supports 4,000 jobs and contributes $600 million annually to New Zealand’s economy. They also observed the company’s efforts to minimise environmental impact, including measures to reduce visual, air and noise pollution.
The visit offered a real-world example of government intervention through subsidies. New Zealand Steel has partnered with the government and Contact Energy to reduce the mill’s carbon footprint. A key project is the construction of a $300 million electric arc furnace, which will replace two of the four rotary kilns as the company transitions to lower carbon production.
This initiative also serves as a valuable case study for comparison with the British steel industry, which earlier this year required urgent government intervention to keep its remaining furnaces in operation.
