Walking the whole length of streams is slow and difficult, but by far the best way to learn about their environmental condition.
As part of work to restore galaxiids to urban streams, NIWA scientists have been monitoring the movement of giant and banded kōkopu.
Year after year the Havelock Mussel Festival is a huge success, drawing crowds of up to 6000 people.
In 2009 there were a record number of 70 stalls which offered food, wine and beer, crafts and industry displays. This was in conjunction with top kiwi entertainment, lots of fun activities - it really is the festival that brings the whole community together.
In 2010 NIWA will again be taking a Gold Sponsorship of the event, sponsoring the The NIWA Kidzone.
NIWA has constructed and commissioned two new research units to provide future support and R&D capability to the New Zealand aquaculture sector as it diversifies and develops. They are: a commercial scale nutrition trials unit at Bream Bay Aquaculture Park near Whangarei, and a disease investigation and challenge unit at our Greta Point campus in Wellington.
Spring is upon us and NIWA’s stock of 86 spawning hāpuku broodstock have emerged from the winter to begin spawning. This is the sixth year we’re spawning from wild-caught broodstock to develop hāpuka as a new high-value aquaculture species.
New Zealand’s green credentials are a key selling point for aquaculture products in an increasingly discerning world market. With the aquaculture industry poised to expand, we need robust tools to manage potential environmental impacts, including those of new finfish species. NIWA’s sustainable aquaculture programme addresses this need.

The risk posed by alien fish to our freshwater species and habitats can now be evaluated using a model developed by NIWA scientists. The Freshwater Fish Risk Assessment Model (FRAM) assesses the risk of new alien fish species becoming established in New Zealand, and, importantly, their capacity to damage the environment, giving an overall ‘ecological risk’.
FRAM is powerful and simple to use.
