Latest news

A little can mean a lot – especially when it comes to the relationship between sea level rise and coastal flooding.
Two reports released today by NIWA and the Deep South National Science Challenge reveal new information about how many New Zealanders, how many buildings and how much infrastructure could be affected by extreme river and coastal flooding from storms and sea-level rise.

NIWA puts a lot of things in the ocean—instruments tied to moorings, floats that dive up and down measuring what’s going on in the water, and video cameras that monitor fish.

Huge mudslides from November’s earthquakes have wiped out all organisms living in the seabed of the Kaikōura Canyon.

Our work

Coastal aquaculture provides one of New Zealand’s biggest opportunities to generate new wealth from the primary production sector.
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.

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.

A low-cost weather station for gathering accurate weather data. Wind speed and direction, air temperature, relative humidity, barometric pressure and rainfall data can be accessed from a server, via the internet.

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.

Many of New Zealand's rivers fail to meet national guidelines for nutrient levels. NIWA has developed the Catchment Land Use & Environmental Sustainability (CLUES) estuary tool to predict the effects of land use on estuarine nutrient concentrations.

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

NIWA is working on a ministry-funded project to produce a model, validated by 40 years of historic data, to project future wave and storm surges off the coast for two climate change scenarios.

Here we provide a detailed summary of key outcomes from the Sustainable Aquaculture programme to 30 June 2009.

In this issue we bring you news of recently completed research on: Tauranga Harbour sediments, the Separation Point fishing exclusion zone, the Bay of Islands Coastal Survey, and mapping coastal environmental values.

NIWA’s Beach Profile Analysis Toolbox (BPAT) has been developed to provide an easy to use, integrated package for the input, quality checking, analysis and archiving of beach datasets.

The High Performance Computing Facility (HPCF) is supercharging New Zealand science—powering scientists working at the forefront of New Zealand’s greatest science challenges.

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.
