Latest news

At the bottom of the Southern Ocean, near Cape Adare in East Antarctica, lies an undersea ridge which until this month was only known by its co-ordinates: -71.2132 latitude, 172.1649 longitude.
New ways to address environmental sustainability challenges.
New measurements from the ocean under the centre of the Ross Ice Shelf have significantly improved our understanding of the complex processes that drive melting in Antarctica.
A little can mean a lot – especially when it comes to the relationship between sea level rise and coastal flooding.

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.

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.

Coasts Update brings you news of coastal research, events, and workshops at NIWA.
