Summer marine pest surveillance has delivered welcome results from Waitematā Harbour, Tauranga Harbour and Ōpua Marina/Waikare Inlet.

Cawthron’s Marine Biosecurity Group has teamed up with Victoria University of Wellington’s Artificial Intelligence Laboratory to develop the world’s first smart trap for invasive crab species.

Marine biosecurity isn't just the job of scientists and biosecurity officers. Sometimes the people who make the biggest difference are simply those who know what to look for.

Auckland boat owners can now use an underwater robot to help keep their hulls clean without moving their vessel from its berth.

A new video explains how the Level of Fouling Scale helps biosecurity teams assess fouling on boats and reduce the risk of marine pests spreading around New Zealand.

In a similar way to the NZ Royal Commission’s enquiry into the country’s pandemic response, experts have investigated the decade-long marine biosecurity response to the Bonamia ostreae (Haplosporidia) so that we can learn from it in future responses. 

New Zealand is already well prepared for increased biosecurity risk from shipping stranded in the Gulf,  thanks to our world-leading biosecurity system.

In July, the Top of the South Marine Biosecurity Partnership welcomed a new coordination team to support the delivery of the Partnership's work across Te Tau Ihu and Greater Wellington.

The $29 million facility represents a significant investment in the region’s marine infrastructure, facilitating improved haul-out, maintenance, and vessel servicing capabilities to support the growing needs of New Zealand’s blue economy.

The Australian government has released a new manual for response to invasive ascidians. 

Exotic caulerpa is serious, but these marine invasions overseas are possibly worse. 

A poor quality in-water clean is seen as the likely reason that Mediterranean fanworm was carried to the Marlborough Sounds this summer.

We talked to Jake McGrath of Brin Wilson Boatbuilders in Gulf Harbour Marina for his expert take on winter maintenance. 

A Virtual Reality Experience will be delivered at Auckland’s two upcoming boat shows which hopes to open your eyes to the magic of our coastlines and the imminent danger posed by pests like exotic caulerpa and Mediterranean fanworm.

A new fouling-release hull coating system is offering boat owners another tool to help reduce the spread of marine pests. 

We love it when we get told about marine pest sightings and so we were stoked to get a heads up from a member of the public who’d spotted something weird on the beaches around Whitianga after the storms in January.

New research is showing how autonomous underwater technology and artificial intelligence could dramatically improve how we detect marine biofouling, and stop invasive species before they spread.

A review by the Cawthron Institute provides updated guidance on use of the Level of Fouling (LOF) scale

The 2025 Annual Forum in Waikato convened marine biosecurity professionals, scientists, council representatives, industry stakeholders, and the public to discuss current challenges, innovations, and collaborative efforts in protecting marine environments from marine pests.
