In New Zealand, residents support $500 million dry dock but push to move it away from homes

A proposed $500 million dry dock in Northland is winning support while also facing criticism over where it would go, as Marsden Bay residents said they want the facility built at a different site.

For nearby homeowners, the issue is proximity. Under the plan, ship maintenance could take place 375 meters from homes.

Here's what to know

The Marsden Bay Residents Association wants the government to move the planned shipyard and drydock 2 kilometers east, placing it within Northport's existing wharf and maritime precinct.

According to 1News, the Ministry of Business, Innovation, and Employment is pursuing fast-track approval for a 250-meter floating dry dock designed to service Cook Strait ferries, naval vessels, and large commercial ships.

Regional Development Minister Shane Jones said $100 million from the government's regional infrastructure fund has been set aside for the project, which he described as significant both for the region and the country, especially with new inter-island ferries on the way. "The scale of this project means construction would provide a significant boost to Northland," he said, per 1News.

Association member Captain Paul Hines, who has over 40 years of maritime experience, said residents are not trying to block the dry dock itself. He said about 150 waterfront homes in the Marsden Bay-One Tree Point area would be among those most directly affected.

The group said its main concerns are noise; air quality; and hull blasting involving materials such as asbestos, lead, copper, and zinc, 1News reported.

More background

Project plans call for reclaiming harbor space roughly equal to 14 rugby fields and require over 753,000 cubic meters of dredging — enough material for about 150,000 10-tonne truckloads.

Hines has argued that the western site also makes less practical sense. He said the area is 7 meters deep, while there is naturally deeper 17-meter water farther east, the outlet noted.

He also said that in 2022 Northport redirected its planned growth toward the east after western-zone marine ecology problems were found. The Environment Court later approved that expansion.

Part of the proposal overlaps the Significant Ecological Area between One Tree Point and Marsden Bay, and the development would wipe out 10 hectares of marine habitat, including 3.9 hectares inside that protected area.

Project documents cited by 1News said hull blasting would be the site's noisiest activity, with sound at times "higher than desirable" for residents in Marsden Bay and Reotahi.

What's being done?

The proposal was submitted to the Environmental Protection Authority on Aug. 20, marked complete Sept. 17, and is now headed to an independent expert panel for review.

An MBIE spokesperson did not directly address residents' request to move the project east, but did outline the next phase of the process, saying, per 1News, "The next step is for an expert panel to be convened to consider the application, determine the appropriate parties to engage with, seek further information if required, and decide whether to approve or decline it."

Residents said they plan to stay involved. Hines said the association will watch closely as panel members are appointed and will seek an opportunity to address the panel.

He also said the group would have preferred a conventional resource consent pathway, arguing that the fast-track route limits community feedback.

Jones has said that a Marsden Point facility would cut transit costs and emissions by allowing major vessels to be serviced in New Zealand rather than making maintenance trips to hubs such as Sydney or Singapore.

"We want the dry dock. But we want it in the right place," Hines said.
