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

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. 

NIWA is looking for people who have had a long association with the Hauraki Gulf or Marlborough Sounds to help them with a research project on juvenile fish habitats.

NIWA is developing guidelines and advice to help coastal communities adapt to climate change.

Most of the plastic in the ocean originates on land, being carried to the estuaries and coasts by rivers. Managing this plastic on land before it reaches the river could be the key to stemming the tide of marine-bound plastics. The aim of this project is to understand the sources and fate of plastic pollution carried by urban rivers using the Kaiwharawhara Stream as a case study.

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.

Antarctic Coastal Marine Life in a Changing Climate

NIWA marine ecologist Dr Vonda Cummings discusses the likely effects of climate change on marine invertebrates living on the seafloor of the Ross Sea coast.

Next Stop Antarctica

Our Far South is an expedition that aims to raise New Zealanders' awareness of the area south of Stewart Island. Gareth Morgan, Te Radar, scientists and 50 everyday Kiwis are onboard to learn and then share their experience. This is the first video produced by them, showing some of the highlights of the trip so far.

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.

We calibrate environmental sensors, at our Christchurch laboratory, using reference instruments that are themselves calibrated to traceable standards by an independent organization.

We service and support individual instruments, systems and nationwide networks.

We install monitoring and control systems of all sizes, throughout New Zealand, in the Pacific Islands and even the Antarctic.

We supply a complete range of environmental monitoring equipment, from small components to large systems. We also supply accessories and miscellaneous items.

We manufacture items such as cables and circuit boards through to subassemblies for both standard and specialized systems.

We develop custom environmental monitoring and irrigation flow-control solutions.

We design instruments and systems of instruments. We have full mechanical and electronic CAD capability.

Instrument Systems offers a number of services, including: design, development, manufacture, supply, installation, service and support, calibration, evaluation, hire, training and service contracts.

A cost-effective water level recorder. Comprises a water surface float-driven shaft encoder and internal data logger with rainfall input. Connects directly to compatible communications devices.

When deployed underwater, this self-contained instrument records and analyses water waves. It can trigger other instruments and send alarms via a communications link.

NIWA has a range of online tools and information relating to tides, including a tide forecaster, yearly tide envelopes and storm tide "red alert" days.

New posters reveal dynamic seafloor

Three new posters reveal the seafloor of the Cook Strait and Wellington Harbour in high resolution detail for the first time. These posters are the product of recent sophisticated seafloor mapping combined with expert marine geological knowledge acquired over decades. They are the culmination of an exceptional collaborative effort among NIWA researchers.

Welcome to Coasts Update, the new quarterly e-newsletter of NIWA's National Centre for Coasts. In this issue, we report on tsunami research, predicting contaminant accumulation in estuaries, seagrass restoration, and a new set of posters depicting the seafloor of Cook Strait and Wellington Harbour.

Seagrass beds form an important undersea habitat for small fish, seahorses and shellfish in New Zealand.
This unique project is the first systematic attempt to quantify and map environmental values of New Zealand's coastal marine ecosystem.
NIWA has developed an Urban Stormwater Contaminant (USC) model to enable urban planners to predict sedimentation and heavy metal accumulation in estuaries and identify problem areas in order to target mitigation measures.
