Small orange flecks spotted floating around in a respiration chamber at a NIWA laboratory have led to a discovery about the spawning habits of a deep-sea stony coral in New Zealand waters.
A six-metre long orange underwater robot is flying through the Kaikōura Canyon for the next month collecting information on how the canyon has changed since the 2016 earthquake.
People along the Kapiti and Wanganui coast may spot NIWA’s research vessel Kaharoa operating close to shore in the next few weeks as scientists carry out a survey of snapper, tarakihi, red gurnard and John Dory.
NIWA scientists have completed the first national assessment of people and buildings at risk in New Zealand’s tsunami evacuation zones.

Our work

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.

Most of the plastic in the ocean originates on land, being carried to the estuaries and coasts by rivers. Managing this plastic on land before it reaches the river could be the key to stemming the tide of marine-bound plastics. The aim of this project is to understand the sources and fate of plastic pollution carried by urban rivers using the Kaiwharawhara Stream as a case study.
Seagrass beds form an important undersea habitat for small fish, seahorses and shellfish in New Zealand.

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.

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.
