New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.
With cascading waterfalls and native bush tumbling down mountainous terrain, Fiordland is one of the most eye-catching parts of the country. But peer beneath the waves and you'll see that Fiordland's marine invertebrate and seaweed communities are every bit as remarkable and awe-inspiring.
A project is under way to determine whether Aotearoa New Zealand’s long defunct rock oyster industry can be revived.
A pilot study carried out by NIWA and the University of Auckland has found microplastics in samples collected from the seafloor in the Marlborough Sounds.

Our work

Clouds over the ocean, and how they trap or emit radiation from the sun, are partly influenced by the biology, biogeochemistry and physics of the surface ocean below.

We need information on the food web structures of our marine ecosystems in order to manage the effects on the ecosystem of fishing, aquaculture and mining, as well as understanding the potential impacts of climate variability and change on our oceans. 

Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.
NIWA is conducting a five–year study to map changes in the distribution of plankton species in surface waters between New Zealand and the Ross Sea.

Dive into the alien world of plankton in the Ross Sea

Plankton are the base of the oceans food web and are vital to our survival. But as our world changes will they be able to continue to play this essential role? Join us as we follow a group of NIWA scientists investigating various aspects of this question in the ocean around Antarctica.

If you want to get accurate scientific readings from the icy depths of the Ross Sea, who do you turn to?
Ocean Acidification
This video has been produced to highlight ocean acidification as a potential issue affecting the NZ shellfish aquaculture industry
Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?

NIWA Oceanographer Dr Craig Stevens has returned, with stunning images and data, from a successful month-long research trip in Antarctica, where he led a team of international and New Zealand scientists.

New Zealand's Kaikoura Canyon is a 'biodiversity hotspot', containing far more life than seen before at such depths.

This measures rain by the drop as well as by the tradional 'tip'. We can configure it either with an SDI12 serial data interface or an integral logger with cellular communications.

NIWA’s research vessel Kaharoa set sail from Wellington today, destined for Lyttelton and equipped with seismic survey gear to survey an area of southern Pegasus Bay.

Preliminary results from the first comprehensive survey of the Cook Strait Canyon seabed have begun to reveal tantalising scientific secrets about New Zealand's largest underwater canyon.

Targeted geological sampling and imaging by NIWA scientists next week will help understand active seabed processes in one of New Zealand's largest seafloor features.

On New Year's Day, NIWA's research vessel Tangaroa departs for its first voyage, since its recent $20 million dollar upgrade, making its twentieth consecutive trip to the Chatham Rise to study the abundance of important fish species.

We are investigating the potential effects of the Antarctic toothfish fishery on the species’ predators by trying to understand how significant a prey toothfish are for seals and whales in the Ross Sea.

We are investigating the effects of the Ross Sea toothfish fishery on prey by looking at what the species eat and trying to understand the biology and ecology of these fish.

Extreme Weather 2011

9 February 2011 to 11 February 2011

The conference will be held in Wellington, NZ and include six special sessions each with a keynote address:
Extreme weather in the Australasian region – from floods to droughts
Impact and meteorology of the main climate drivers (ENSO, SAM, Monsoon)
Using high resolution models to understand local meteorology
Oceanography of the Australasian region
Climate change in the Australasian region
Impacts of natural catastrophes in the Australasian region
However papers on any topic related to the Atmospheric Sciences (including composition) and Oceanography of the Australasian region will be co

Our Quality Management System is our commitment to quality, productivity, consistency and customer satisfaction.

NIWA holds ISO9001:2015 certification.

The Instrument Systems group is located at NIWA in Christchurch, New Zealand. Our 16 staff have a diverse range of technical, engineering and science skills, and we have extended capability from being part of a wider team.

We provide training in the use and maintenance of our instruments, software and data collection systems.

We offer service contracts to minimize downtime if an instrument fails. We keep a full range of spares in our Christchurch store and can courier a spare to the contract holder on receiving a request.

We evaluate new products to ensure that they're 'fit for purpose' before we approve them for widespread use.
