Atmospheric analysis

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.

A high proportion of New Zealand’s native freshwater fish fauna need to migrate to and from the sea.

Station height is in metres above mean sea level. Years of data are the number of complete years of data for the 1981 – 2010 period.

Mountainous areas are subject to heavy snowfalls, high winds, and low temperatures. Semi-permanent snow and ice fields exist at about 1000-1100 metres during winter.

National climate maps

The process of coming to work with us has five steps: applying, a phone interview, a face to face interview, background checks, and an offer.

Maps of the average first and last dates of soil moisture deficit are shown here.

Tuna or freshwater eels are a very significant, widely-valued, heavily-exploited, culturally iconic mahinga kai resource.

Accurate reporting on the amount of fish and invertebrates that are caught and discarded by New Zealand’s commercial fishing industry is vital to effective management of these fisheries.

NIWA is doing a nationwide study to discover what makes the best riparian projects. Help us give you the knowledge to make the best riparian management decisions possible by taking our 5 minute survey.

The scientific records of palaeotsunamis to have affected New Zealand shores can now be accessed in a new one-stop information shop.
