New Zealand: Holcim New Zealand has confirmed it will sell its cement carrier MV Buffalo, a source of local employment, to Switzerland-based NovaAlgoma Cement Carriers (NACC) at the end of 2025.
A Holcim spokesperson said “Holcim has decided to sell the MV Buffalo and source a replacement vessel. The 27-year-old MV Buffalo is too large, inefficient and costly to run, requiring in excess of US$4.5m in repairs and maintenance over the next four years in order to remain seaworthy. The decision follows a comprehensive review of Holcim’s shipping requirements and operational costs. The review identified the need for a more modern, smaller and cost-effective vessel to maintain supply of cement to the South Island and lower North Island.”
The company began consultation to retire the MV Buffalo in February 2025, and has since confirmed future shipping will be managed by NACC. However, NACC must obtain a government exemption to operate the Panamanian-flagged NACC Vega in domestic waters.
The Maritime Union of New Zealand (MUNZ) has opposed the move and urged the government to reject NACC’s flag waiver application. Holcim has reportedly issued formal termination notices to the MV Buffalo’s 32 New Zealand-based crew, effective 28 December 2025. Union negotiations remain unresolved since October 2025 and have been referred to the Employment Relations Authority.
