Ask a room full of boaties, commercial operators and marina managers about marine biosecurity and you'll probably hear a range of opinions. For some it's common sense. Others question whether the investment is worthwhile

Last summer Waikato Regional Harbourmaster Chris Bredenbeck did some informal testing on his 40 foot launch, Te Wairua. What did he find?  

Don’t leave it until the last week because haulouts, hardstands and contractors are talking about a busy summer ahead. For boat owners that means a need to get in contact with their favourite facility and make bookings if they are going to get lifted, washed or antifouled ahead of the summer cruising season.

How an invasion of blue crabs has devastated a historical fishing industry in Italy.

It’s here! The official opening of a new 110-tonne Cimolai travel lift at Nelson Marina on 21 September is good news for marine biosecurity and boat owners wanting more maintenance options. The new lift doubles the marina's previous lifting capacity and can accommodate vessels with a beam of up to 8.5 metres, including larger boats and multihulls.

Keeping boat hulls clean is important for preventing the spread of marine pests, reducing drag and improving fuel efficiency. But new research has confirmed another environmental issue: the tiny fragments of antifouling paint released when vessels are cleaned in the water.

A new exhibition at Mercury Bay Museum in Whitianga explores the challenges facing the Hauraki Gulf and the work underway to restore its marine environment.

Get ahead of the rush! Boat owners planning to go cruising this summer are being encouraged to plan and book their summer hull maintenance now, before boatyards and marine trades enter their busiest period.

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.
