Excessive nutrient input (eutrophication) threatens many New Zealand estuaries causing ecological problems, such as algal blooms and poor physical and chemical conditions for estuarine life.

Does climate change affect the position of the Subtropical Front around New Zealand? This has important consequences for New Zealand's climate and biological productivity.

NIWA is undertaking a five-year nationwide study to find out how different approaches to riparian planting influence water quality improvements and to provide better guidance to the people and groups undertaking stream restoration.

Māui dolphins, a subspecies of Hector’s dolphins, are listed as nationally critical in New Zealand with a population estimate between 57 and 75 dolphins over one year old.

Biological traits analysis is a valuable tool for measuring ecosystem function.

NIWA has recently created synthetic, multi-year, 10-minute wind datasets at 15 wind farm sites across New Zealand. These will be used by the Electricity Commission to model the impact of wind farms on the national grid.
