William Fraser
At 68 metres, William Fraser is the newest ocean-going vessel in our fleet. She was built from scratch at the Berjaya Dockyard in Miri, Malaysia, to Bureau Veritas standards, and is surveyed for international voyages. She is named after the founder of McCallum Bros and the late “Uncle Bill” McCallum.
Her main job is sand extraction, but she is available for charter and specialises in fuel transfer and roll on, roll off work. Her ramp and entry hopper are 8 metres wide, and her low emission engines meet U.S. EPA Tier 4 Final standards.
Recent work includes delivering solar and infrastructure materials to Tokelau, carrying 6,000 tonnes of armour rock from Tarakohe to Wellington, maintenance dredging at Marsden Point, and launching our Chatham Islands freight and livestock service in 2026.

New Chatham Islands vessel
A purpose-built livestock and general freight vessel being built for 44 South Shipping, the joint venture between McCallum Bros and Nova Marine Carriers. She will replace the MV Southern Tiare and provide a reliable shipping service for the Chatham and Pitt Islands for the next 20-plus years.
The vessel is a fully enclosed livestock carrier with three internal livestock decks. Her ventilation system, designed by Tecnavi, keeps a steady flow of clean air across every deck and has a dedicated secondary generator, so livestock keep clean air, fresh water and feed even if the main power systems are unavailable.
