Partnering to build $36m dredge

The 26-month build of Port Otago and Napier Port’s new $36m dredge is on schedule for a late 2026 delivery to New Zealand.

In December, Port Otago and Napier Port announced a joint venture to invest in a state-of-the-art trailing suction hopper dredge from Dutch shipbuilder Damen Shipyards.

The partnership builds on a collaborative relationship between the two ports and sees the formation of a new dredging company, via a Limited Partnership Agreement.

Given New Zealand’s relatively small size, the investment is a financially astute approach to ensuring the country’s port infrastructure is well placed to meet the future demands of global shipping. From a safety and resilience perspective, it protects the two ports’ shipping channels and harbour access for future generations.

Port Otago will manage and operate the dredge, leveraging its 150 years of expertise in dredging operations. 

Chief Executive Kevin Winders emphasises the broader benefits. “This collaboration between two like-minded ports strengthens New Zealand’s maritime infrastructure.

Shared ownership of the TSHD-1000 enhances operations at both ports and reduces duplication of investment within the sector.”

He says the acquisition aligns with both ports’ commitments to sustainability and environmental stewardship. “The new Damen TSHD-1000 is fitted with industry-leading dredging and monitoring systems.

“Replacing our 40-year-old New Era suction hopper dredge with such advanced technology will improve operational efficiency, reduce our carbon footprint, and operate with a lighter touch on nature.”
