New findings from the record-breaking Tongan volcanic eruption are “surprising and unexpected”, say scientists from New Zealand’s National Institute for Water and Atmospheric Research (NIWA).
NIWA is contributing to an international effort to help developing countries reduce the impact of biofouling on aquatic-based industries and environments.
NIWA and The Nippon Foundation are undertaking a mission to discover the undersea impacts of the recent Tongan volcanic eruption.
A robot sea craft is the latest tool NIWA scientists are using to help them count fish.

Our work

Aotearoa New Zealand’s coastal lowlands are our flat low-lying land (or plains) adjacent to coasts and estuaries. Our coastal lowlands are valued for many reasons, including unique ecological wetlands, cultural sites of significance, valued recreational areas, highly-productive agriculture and are popular places to live.

We need information on the food web structures of our marine ecosystems in order to manage the effects on the ecosystem of fishing, aquaculture and mining, as well as understanding the potential impacts of climate variability and change on our oceans. 

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.

NIWA is developing guidelines and advice to help coastal communities adapt to climate change.

Plankton are the base of the oceans food web and are vital to our survival. But as our world changes will they be able to continue to play this essential role? Join us as we follow a group of NIWA scientists investigating various aspects of this question in the ocean around Antarctica.

Next Stop Antarctica

Our Far South is an expedition that aims to raise New Zealanders' awareness of the area south of Stewart Island. Gareth Morgan, Te Radar, scientists and 50 everyday Kiwis are onboard to learn and then share their experience. This is the first video produced by them, showing some of the highlights of the trip so far.

New Zealand continues to punch above its weight in global environmental issues, with three Kiwis seeking a positive change to our oceans in Washington this month.

This Habitat Mapping module will show you how to collect useful information to describe and monitor habitats in estuaries.

While Tangaroa might be considered its flagship, NIWA’s extensive range of maritime work could not be completed without the support vessels Kaharoa and Ikatere.
A team of scientists aboard NIWA’s deepwater research vessel Tangaroa returned to Wellington with new knowledge about methane ‘leaking’ into the atmosphere.

This week, New Zealand's leading coastal scientists, engineers and planners are attending the New Zealand Coastal Society 20th Annual Conference in Auckland. NIWA has many speakers presenting work at the conference.

NIWA research vessel Kaharoa will depart Wellington on Friday 12 October to deploy 120 Argo robotic instruments across the Pacific Ocean.

Scientists have discovered that our big birds take long winter holidays overseas. The native Campbell Albatross take off to South Australia, and the Grey-headed Albatross goes further afield to an area 7,000 km from Campbell Island, in the Indian Ocean to the west of Australia.

Understanding how material released into the ocean spreads is very important in the case of oil spills, sediment transport and the release of invasive species. 

NZ Coast is a collection of information about the New Zealand coastal environment and related hazards.
