NIWA scientists have set up air quality sensors every 100 metres across Arrowtown in what is believed to be the world’s densest air monitoring network.
A buoy with the ability to “phone home” has been deployed in Wellington Harbour today to monitor currents, waves and water quality in the harbour.
NIWA researchers have spent part of the last month keeping a close eye on the bottom of Lake Tekapo to find out what it looks like and what is going on below the lake bed.
NIWA’s Fieldays team is basking in the glory of winning the Best Indoor Agribusiness Site awarded by the National Agricultural Fieldays organisation for the 2015 event.

Our work

Climate Present and Past is a core-funded project under NIWA's National Climate Centre. It aims to explore historical climate data and track past changes in climate through a range of approaches.

ARGO - measuring salinity and temperature across the oceans
Since the early 2000s, NIWA has been part of the international Argo programme. Argo floats takes the pulse of the oceans, collecting and distributing temperature and salinity observations from a global network of more than 3700 underwater robots.
Exploring the deepsea

Despite many centuries of maritime exploration, only a fraction of our planet's seafloor has been observed. NIWA Deepsea Scientist Di Tracey tells us what it feels like to probe deep beneath the waves to see what's living on the ocean floor.

NIWA IrriMet
NIWA has developed new tools that can help farmers decide when to irrigate or fertilise.

The WP Series measures Electrical Conductivity, Total Dissolved Solids, Dissolved Oxygen, Turbidity, Temperature, pH, Redox and Specific Ions.

A portable multi-parameter instrument for measuring water quality; Electrical Conductivity, temperature, pH, Oxidation Reduction Potential, Dissolved Oxygen and Turbidity.

This multiparameter recording instrument enables 'quick calibrations', automated low-flow sampling, has field-replaceable sensors and a long-lasting internal power source.

When water becomes super-saturated with gases it can become lethal to fish. So monitoring the Total Dissolved Gas can be important for effective water quality management.

This uses optical fluorescence sensing technology to provide an extremely stable, precise and low maintenance dissolved oxygen sensor.

This sensor provides accurate and precise turbidity readings over a range of adverse environmental conditions.

This sensor is versatile, offers superior features, high reliability and tolerates rough treatment in harsh environments.

This sensor is versatile, offers superior features, high reliability and tolerates rough treatment in harsh environments.

The Greenspan Analytical Electrical Conductivity Sensors provide highly accurate conductivity measurements in a wide range of hydrological applications.

The Greenspan Analytical Dissolved Oxygen Sensors provide accurate long-term measurements under a wide range of environmental conditions.

The Greenspan Analytical Conductivity/Temperature/Dissolved Oxygen/pH sensor provides numerous technical features.

We can supply, configure or install suitable communications instruments to collect your environmental data from near or far.

We can supply a number of miscellaneous products and accessories that you may find useful for supporting various monitoring operations.

A comprehensive list of all of the instrumentation available for hire through NIWA.

We can supply a wide range of weather or climate monitoring instruments from single parameter sensors to fully equipped and installed climate stations.
Data loggers range from simple standalone recording devices that can be manually downloaded, to Internet-capable remote terminals that can push their data to a server that users can access via an Internet browser.

Water flow instruments range from small acoustic doppler current profiling devices or small prop type meters for measuring very low flows in small streams, up to NIWA's flood-gauging POEM.

There are different types of instrument available for measuring water level. Each has its strengths and weaknesses. It's important to select an instrument that's right for your application to ensure you'll get reliable data.

Water Quality instruments may measure one or more parameters including: electrical conductivity (EC), dissolved oxygen (DO), water temperature, turbidity, total dissolved solids (TDS), Redox, specific ions and pH.

Here is our complete range of products. Many are available for sale or hire from our Christchurch store.  Alternatively, if we don't have what you require in stock we can order it from our suppliers.

This analog output sensor provides accurate long-term measurements of water depth and temperature in bores, drains and rivers.

This ultrasonic Doppler instrument is a compact, easy to use system for measuring water flow in rivers, channels and pipes.
