Napier Port and a partner port, Otago, have teamed up to buy a $36 million new dredging ship.
Dutch company Damen Shipyards will build the ship at a shipyard in Vietnam and it is expected to be ready in late 2026.
It will be based in Dunedin but called upon when needed at Napier.
The ship that is being bought is known as a Damen TSHD-1000 and is 59m long.
Napier Port declined to say how much it would contribute in terms of its share of the $36m investment or how often it expected to use the ship each year.
