John Clayton, a principal scientist in the fields of aquatic biodiversity and biosecurity based at NIWA's Hamilton office, has won a 2011 Kudos award for his leading role in the development of LakeSPI  (Lake Submerged Plant Indicators).

NIWA's work seeks to improve our understanding of the key dynamic and physical processes which are responsible for heavy rainfall , and to improve the heavy rainfall forecast.

A problem with recruitment is usually indicated by the absence, or very low density, of fish where they would normally be present.

Fish species thrive in a variety of different habitats.
