The New Zealand Defence Force and Customs Service have welcomed two new uncrewed surface vessels—Tahi and Rua—into service, marking a significant leap in coastal protection.

The USVs were unveiled during a naming ceremony at Devonport Naval Base yesterday.

Built by Australian company Ocius Technologies, the vessels are designed to enhance maritime surveillance and disrupt organised crime.

This is the first time New Zealand has introduced this type of cutting-edge technology to help patrol its vast ocean borders.

The USVs operate without crew on board and can remain at sea for extended periods, gathering real-time intelligence and improving rapid response capabilities.

Their arrival follows a successful seven-month trial in 2024, where one USV was involved in seizing seven kilograms of cocaine hidden on a ship heading to Auckland.

Air Marshal Tony Davies and Customs Comptroller Christine Stevenson formalised the acquisition in October with a Memorandum of Understanding between Defence and Customs.

Customs Deputy Chief Executive Jamie Bamford said the vessels are a practical and cost-effective way to respond to increasing threats from drug-smuggling syndicates across the Pacific.

“The USVs allow us to monitor in real time and act quickly. That’s a game-changer when it comes to securing our coastline,” he said.

Royal New Zealand Navy's Commodore Shane Arndell praised the inter-agency teamwork that made the acquisition possible.

“The addition of Tahi and Rua means we can maintain a persistent watch over New Zealand waters—and beyond,” he said.

Coasties may not see these vessels up close, but their silent presence offshore adds another layer of protection for the nation’s maritime borders.
