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.
NIWA researchers are heading out from Tasman early next week to survey an area thought to be home to important juvenile fish nurseries.

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.

The Neon Applications software is a suite of software and documentation which allows clients to set up their own Neon system on existing server hardware, or new server hardware located at the client’s premises.

The NRT is a small self-contained unit which connects to sensors, records readings from them and transmits the data to a central server via satellite communications.

Welcome to the latest edition of Coasts Update. Here we bring you news of some of NIWA's latest research on aspects of coastal ecology, and the possible impacts of climate change on one of our coastal communities.

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.

A self-contained telemetered inshore buoy capable of being equipped with a wide range of marine sensors.

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.
