Our work

Aotearoa New Zealand’s coastal lowlands are our flat low-lying land (or plains) adjacent to coasts and estuaries. Our coastal lowlands are valued for many reasons, including unique ecological wetlands, cultural sites of significance, valued recreational areas, highly-productive agriculture and are popular places to live.

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.

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.

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.

For many of us, summer isn’t summer without getting some sand between our toes. But did you ever wonder what that sand is made of, and how it got there?

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.

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.
