The New Zealand government has granted Golden Bay Cement up to $60 million to keep its Portland plant near Whangārei operating until at least 2040. The plant supplies nearly 60% of the country's cement and was at risk of closure due to rising costs, particularly from carbon emissions pricing under the Emissions Trading Scheme. The government said losing domestic production would leave New Zealand exposed to global supply disruptions for cement, which has no practical substitutes for building homes, hospitals, roads, and infrastructure. Under the deal, Golden Bay Cement must commit at least $150 million of its own investment, maintain jobs, and submit to additional reporting and auditing. The government can claw back funds if obligations are not met. The company's CEO said without support, rising carbon costs that overseas competitors do not face at the same level would have forced a shift to imports by 2030. The funding was included in Budget 2026 as a tagged contingency. This case highlights the tension between carbon pricing integrity and industrial competitiveness. The government explicitly chose a direct grant over regulatory relief to avoid undermining the ETS. It also shows how carbon costs are reshaping heavy industry decisions, even in countries with relatively modest emissions pricing. The plant directly employs over 150 people and supports 450 additional jobs in the region.
