Research

NIWA expends considerable effort on determining the age of commercial fish species. But why age a fish? And how do we do it?

Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?

A range of physical and chemical variables are measured in the NRWQN.

Projections of how climate change is likely to affect New Zealand.

Maps of average annual rainfall, temperature and other climate variables have been produced for all of New Zealand, based on the period 1981–2010.

The current method for calculating wind speed-up is inadequate, and can grossly under-predict correct design wind speeds in NZ's complex terrain.

There are many lines of evidence showing that NZ has warmed during the past century.

NIWA's research on freshwater monitoring and reporting is one of three research areas within the 'Values, Monitoring and Outcomes' (VMO) programme led by Landcare Research.

NIWA is leading a new six-year research project that seeks to increase our understanding of piharau/kanakana/lamprey, using Mātauranga Māori, social science and biophysical science approaches.

CFCs have damaged the ozone layer and led to higher UV levels and increased health risks. Our role is to understand the causes and effects of ozone depletion, to inform the public of the risk.

NIWA provides national capabilities in Water Quality Monitoring

Rig shark is an important inshore commercial fish species in New Zealand, and we need to understand more about their habitats, movements, nursery grounds and vulnerability to human impacts to ensure they are managed sustainably and their productivity is enhanced.
