Biosecurity

Latest news

Visitors to NIWA’s stand at this year’s Fieldays are invited to go diving into the Rotorua lakes—without having to get wet.
Scientists have launched a worldwide crowdsourcing competition aimed at finding novel ideas to tackle invasive marine pests, with a cash prize of $US10,000 on offer.
Every year NIWA carries out numerous marine surveillance missions, surveys at ports and harbours around the country. Their divers are looking for the pests that have hitched a ride to New Zealand waters and are capable of destroying our unique ecosystems and shellfish industry.

When you are at the beach or harbours this summer, don't be surprised if you see sea squirts - marine animals we commonly see attached to rocks and wharf piles that have two siphons on the top of their bodies, one to draw in water and the other to expel it. When disturbed, sea squirts contract their siphons, expelling streams of water—hence their name.

Our work

This project seeks to understand and better implement a Māori perspective within the current marine biosecurity system in New Zealand.
A significant threat to the biosecurity of New Zealand's freshwater habitats comes from plants that have been intentionally introduced.
Of the more than 70 aquatic plant species naturalised in New Zealand, more than 75% have become problem weeds or have been assessed as having the potential to become future problem weeds. Most of our lakes, rivers and streams are affected by at least one of these species.

Understanding how material released into the ocean spreads is very important in the case of oil spills, sediment transport and the release of invasive species.

Diving deep to check up on our lakes

NIWA scientists jump overboard to check out the health the Rotorua Te Arawa lakes. The work is part of NIWA's national LakeSPI programme—an ecological health check for lakes throughout New Zealand.

Robotic vehicle on the lookout for biosecurity pests
Foreign marine pests can threaten our marine life and it’s important to find them early before they can set up home here.
This is a user guide on non-native fish, reptile, invertebrate, algal and plant species that are recorded in New Zealand freshwaters.

Boaties, beware this summer of a weird hitch-hiker waving at you in the water, as a peculiar marine amphipod crustacean, Caprella mutica, may be freeloading on your boat hull.

Scientists at NIWA and Auckland University have discovered that the fouling of vessels by marine creatures is greatly increased by the underwater sounds generated by the vessels themselves.

International Congress for Conservation Biology

5 December 2011 to 9 December 2011

NIWA is sponsoring the 25th International Congress for Conservation Biology.

NIWA staff are running three workshop 'Think Tanks' before the conference, these worksops are:

Implications of environmental change to Antarctic ecosystems 2, 3, 4 December, for more information contact [email protected] 

Deep-sea coral research to enhance conservation 2, 3 December, for more information contact [email protected]

Exotic aquatic plants, introduced to New Zealand for the aquarium and ornamental pond trade, are silently invading our waterways, but new research by NIWA scientists is helping to lower this risk by finding native alternatives for the trade.
A new web portal offers a previously unseen record of the marine pests that threaten New Zealand's marine environment.

New research on the effectiveness of the herbicide endothall shows favourable results in the battle to rid lakes and rivers of New Zealand’s most invasive aquatic weeds, including hydrilla, hornwort and lagarosiphon (an oxygen weed).

Fact sheet and media information.

Welcome to the second edition of Asia-Pacific Update, our newsletter focusing on NIWA's international work in the Pacific, Southeast Asia and Australia. In this edition we focus on some of our recent aquatic biodiversity and biosecurity work in the region.

This unique project is the first systematic attempt to quantify and map environmental values of New Zealand's coastal marine ecosystem.
Different groups of organisms need trained specialists (taxonomists) to distinguish a new species from one that is already named and scientifically described
