The Te Kuiti plant, situated near Waitomo on the North Island of New Zealand, operates a unique vertical kiln that produces high-quality quicklime. Graymont employs highly trained and specialized staff to run this state-of-the-art facility.

The Makareao lime plant is located in the calcium-rich area of North Otago, on the South Island of New Zealand. It is supplied with limestone from its own on-site quarry, which is well known for its exceptional quality, yielding pure limestone of 96-98% calcium carbonate.

The Makareao manufacturing facility produces high-quality quicklime, hydrated lime and pulverised limestone products, primarily supplying customers across the South Island.

Graymont owns and mines New Zealand’s largest single lime quarry at Oparure, just North of Te Kuiti on the North Island. This 67-hectare quarry is located on top of the rich Waitomo strata and produces exceptionally high-grade limestone to supply the Company's Otorohanga and Te Kuiti Plants.

The Oparure plant, which predominantly supplies custmers across the North Island, also manufactures a range of high-quality pulverised Limestone products such as Aglime, Calcimate(R) and industrial fine lime in bulk, sacks and paper bags,as well as aggregates in bulk.

Graymont's Otorohanga lime plant, situated 20 km north of the Company's Oparure quarry, operates two rotary lime kilns to manufacture high-quality quicklime and hydrated lime products from the raw limestone sourced from the quarry. These products supply domestic customers in New Zealand as well as customers in the Asia-Pacific region.

Laboratory staff and other specialists constantly monitor operations at Otorohanga, testing and reporting at least daily to ensure quality and consistency of the plant's output. In addition, experienced production, engineering and maintenance teams work tirelessly to maintain, manage and improve operations.

In addition to its lime operations, the Joliette plant is also a major producer of construction aggregates and pulverized limestone. Graymont has always focused strongly on providing employees with a high quality working environment. This in turn is reflected in the high-quality service offered by plant personnel.
