The 20-year-old vessel arrived from Lyttelton and was alongside the Fryatt St berth for four days, and last Friday evening departed for Timaru. The ship is due back next month.
The New Zealand-flagged ship is 130m long, with a beam of 18.4m and draught of 6m, with a (laden) deadweight of 9092 tonnes, and was purchased from Holcim Vietnam.
The agent for the ship is the private company Milburn New Zealand, which is 100% owned by Holcim (New Zealand) Ltd, which is ultimately 100% owned by Amsterdam construction giant LafargeHolcim.
Milburn manufactures, markets and distributes cement, concrete, aggregate and lime around the country plus delivers to China.
Holcim's Buffalo first arrived at Port Nelson on January 2017 to replace the 29-year-old Milburn Carrier II to become the company's sole domestic ship cement bulk carrier, the Nelson Mail reported at the time.
Holcim's Westport cement plant is closed, so Buffalo distributes cement from Timaru to terminals around the country including Dunedin, Lyttelton, Nelson, Wellington and New Plymouth.
