Holcim New Zealand has officially opened its new concrete plant in Dunedin, strengthening supply capability across Otago and positioning the company to support a growing pipeline of residential, commercial, and infrastructure projects.
The new facility marks a key step in the company’s expansion in the South Island, with national engineering and capital projects manager Sanil Sabu saying the investment reflects both market demand and long-term strategic planning.
“This plant is a really important part of how we grow our presence in the South Island,” Sanil says.
“We have a strong footprint in the North Island with more than 20 plants, and we are now focused on building on our capability further south.”
The Dunedin plant is capable of producing up to 70 cubic metres of concrete per hour, supporting a wide range of projects across the region.
“We are looking to develop our people and create opportunities locally,” Sanil says.
The facility was delivered with support from a number of specialist project partners, including engineering consultancy BG&E, who provided integrated civil and structural engineering services. BG&E was responsible for the design of foundations for silos and key processing equipment, as well as civil site works that support efficient plant layout and operational flow.
BG&E also coordinated engineering inputs during the consenting process and maintained a hands-on role throughout construction, providing site monitoring and inspections through to final sign-off.
While the long-anticipated Dunedin Hospital development is expected to be a significant contributor to demand, Sanil says the wider economic environment is creating some caution. “But we are ready to supply when the work comes through.”
Sustainability is a major focus for the new plant. Holcim’s ECOPact low-carbon concrete is available from the Dunedin site, offering a product that reduces carbon emissions by at least 30 percent compared to ordinary Portland cement concrete.
ECOPact reduces embodied carbon using an innovative mix of supplementarycementitious materials and admixture technology and comes with a product-specific EPD registered with EPD Australasia, providing transparent information about the environmental impact of the concrete. Sanil says interest in low-carbon solutions is growing, particularly among council and government projects.
“There is definitely more demand for sustainable options,” he says. “ECOPact performs as well as standard concrete, and in some cases even better, so it is a strong option for projects looking to reduce their carbon footprint.”
The Dunedin plant currently employs a small team including a manager, batcher, and support staff, with opportunities to grow as demand increases. Training and development are a focus, with plans to build capability across batching operations and quality testing roles. “We are looking to develop our people and create opportunities locally,” Sanil says.
“As the workload increases, there will be scope to expand the team and bring in additional roles, including concrete testing.”
Delivered with support from Fulton Hogan and Holcim teams across the South Island, the plant represents a significant investment in regional infrastructure. Sanil says it reinforces the company’s long-term commitment to Otago and its confidence in future growth.
“This is about being ready for what is coming,” he says.
“We have the supply, the capability, and the products to support the region as it continues to develop.”
