Golden Bay Cement

What Golden Bay Cement does

Golden Bay Cement is New Zealand's longest-standing cement manufacturer, operating as a division of Fletcher Concrete and Infrastructure Limited under publicly listed parent Fletcher Building Limited (NZX). The company runs a single 967,000-tonne annual capacity Portland cement plant at Portland, near Whangarei, and supplies cement, supplementary cementitious materials (EcoPlus Fly Ash, Silica Fume), and ready-mix concretes to the New Zealand construction industry. Its portfolio comprises five primary products: EcoSure Type GP (NZ's lowest-carbon GP cement at 703kg CO2e/tonne, 27% below the ISC 2020 baseline), EcoZero (carbon-neutral variant offset through Toitū Envirocare credits), EcoFast Type HE (high early strength), EcoPlus Fly Ash, and Silica Fume.

Manufacturing technology is based on dry-process Portland cement with a preheater tower modified for biomass and waste-tyre substitution, using FLSmidth's hotdisc combustion module to process end-of-life tyres at approximately 1,400°C. Alternative fuels have displaced approximately 50% of thermal coal, and the company has secured ISO 9001 certification, an Environmental Product Declaration for Global Warming Potential, and a 2023 Declare Label. Golden Bay is committed to a 30% carbon reduction by 2030 and has received a NZ$13.6 million Waste Minimisation Fund grant for the tyre project.

Revenue is generated through direct bulk sales to enterprise concrete and precast customers (Stevenson Concrete, Stresscrete, Supacrete, Bowers Brothers, Counties ReadyMix), merchant-channel bagged cement sales (PlaceMakers, Mico), and a free O2D Customer Portal for order management. Distribution is supported by 15 service and distribution centres, 42 road tankers, two marine vessels (MV Aotearoa Chief and MV Marsden Bay), and 850 ISO tanks, providing nationwide NZ coverage with next-day delivery on bulk orders placed by 3pm. Strategic partnerships include Genesis Energy (Huntly Power Station ash), Toitū Envirocare (carbon offsets), TR Group (hydrogen-powered trucks), and FLSmidth (combustion technology).
