Small orange flecks spotted floating around in a respiration chamber at a NIWA laboratory have led to a discovery about the spawning habits of a deep-sea stony coral in New Zealand waters.
A six-metre long orange underwater robot is flying through the Kaikōura Canyon for the next month collecting information on how the canyon has changed since the 2016 earthquake.
People along the Kapiti and Wanganui coast may spot NIWA’s research vessel Kaharoa operating close to shore in the next few weeks as scientists carry out a survey of snapper, tarakihi, red gurnard and John Dory.
NIWA scientists have completed the first national assessment of people and buildings at risk in New Zealand’s tsunami evacuation zones.

Our work

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.
Seagrass beds form an important undersea habitat for small fish, seahorses and shellfish in New Zealand.

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 ISO9001:2008 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.
