The return of the upgraded RV Tangaroa represents a huge advancement for New Zealand science and exploration

NIWA today welcomed home RV Tangaroa, New Zealand’s only deepwater research vessel, after a $20 million dollar upgrade to enhance its ocean science and survey capabilities.

Summer Series 11: The little blue penguin – our very own ‘Happy Feet’

29 April 2010

They are tiny, burrow under the boards of your seaside bach, and make a heck of a lot of noise in the dead of night. They think night-time is the right time for … calling loudly in a raspy voice!

Summer Series 10: Super snapper! Delicious!

29 April 2010

Snapper are New Zealand’s most prized fish; they are the fish fishermen love-to-love. They live in a wide range of habitats in New Zealand’s warmer coastal waters, around the North Island and the top of the South, and prefer depths of 5–60 metres. They grow to a decent size: up to 105 cm in length.

Our work

Historical changes in juvenile fish habitats

NIWA is looking for people who have had a long association with the Hauraki Gulf or Marlborough Sounds to help them with a research project on juvenile fish habitats.

Plankton biodiversity in the Southern Ocean

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.

Effects of ocean acidification on plankton in New Zealand waters

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.

Kaikoura Canyon survey

New Zealand's Kaikoura Canyon is a 'biodiversity hotspot', containing far more life than seen before at such depths.

The microbial loop refers to the small microscopic organisms in the ocean – viruses, bacteria, the small phytoplankton and microzooplankton – and the relationships between them.

Antarctic Marine Food Webs

NIWA biological oceanographer Dr Matt Pinkerton discusses the complexities of Antarctic marine food webs, the uniqueness of many of Antarctica's marine animals and the extreme adaptations they display.

Kermadec trench biology voyage November - December 2017

This voyage is the first of a series of expeditions exploring selected trenches of the Pacific Ocean, starting with the Kermadec trench. It will investigate carbon and nutrient cycling by microbial communities in trenches exposed to different rates of organic carbon supply.

Summer Series 9: Surf beach burrowers

29 April 2010

Think you’ve got your favourite surf beach to yourself? Think again! There’s life hidden beneath those waves.

“It may look barren, but the high-energy surf zone of exposed beaches is a very productive place, second only to coastal upwellings,” says Keith Michael, a fisheries scientist at the National Institute of Water and Atmospheric Research (NIWA). “It’s rich in phytoplankton [microscopic plants], such as diatoms, that provide a constant ‘soup’ for animals tough enough to survive the waves.”
