Latest news

NIWA researchers are heading out from Tasman early next week to survey an area thought to be home to important juvenile fish nurseries.
After a decade-long effort, NIWA’s latest Biodiversity Memoir has just rolled off the presses. Written by marine biologist Kareen Schnabel, the 350-page treatise presents everything we currently know about the different kinds of squat lobster living in New Zealand’s waters.
Five specialist NIWA divers were left ‘gasping’ during their recent plunge under the ice near Scott Base.
For more than 20 years NIWA scientists have been nurturing three plants that are the only examples of their kind in existence.

Our work

The ability to properly manage our freshwater resources requires a solid understanding of the flora and fauna which live in and interact with them.
NIWA hosted an IPBES workshop entitled “Visions for nature and nature’s contributions to people for the 21st century” held from 4-8 September 2017 in Auckland.
NIWA is conducting a five–year study to map changes in the distribution of plankton species in surface waters between New Zealand and the Ross Sea.
Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes.

The NIWA Biodiversity Memoirs are comprehensive, definitive, illustrated reference works that capture the rigorous, peer-reviewed scientific study of New Zealand’s distinctive marine fauna and flora.

An international team led by scientists from the United States and New Zealand have observed, for the first time, the bizarre deep-sea communities living around methane seeps off New Zealand’s east coast.

New Zealand’s marine and freshwater environments are extremely important for our economic and social welfare, but they are under constant pressure from human uses and introductions of new invasive species.
