Atmospheric analysis

This national GIS ‘layer’ enables reconnaissance-scale estimation of suspended-sediment yields from New Zealand’s rivers and streams. It has been developed by NIWA in collaboration with Landcare Research.

Virtual climate station estimates are produced every day, based on the spatial interpolation of actual data observations made at climate stations located around the country.

Estuaries are at the bottom of the freshwater drainage network and, effectively, are a part of it.

NIWA has transformed 1.5 million square kilometres of data into the most accurate and detailed map yet of the land underneath the sea around New Zealand.

There are two species of kōura or freshwater crayfish in Aotearoa.

Waterways can easily become contaminated by pathogens when effluent is discharged nearby.

The Statement of Core Purpose spells out why the Government owns Crown Research Institutes and what it expects from them.

As much of this climate zone is sheltered by high country to the west, south and in some areas to the east, it is the sunniest region of New Zealand.

NIWA collects wave data, develops and verifies wave forecasting systems, and is developing and producing wave projections.

NIWA operates about 30 other Maritime New Zealand-certified vessels based at Bream Bay, Auckland, Hamilton, Rotorua, Turangi, Wellington, Nelson, Greymouth, Tekapo, Christchurch, and Dunedin.
