NIWA scientists have completed the first national assessment of people and buildings at risk in New Zealand’s tsunami evacuation zones.

Our work

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.

Coastal adaptation to climate change

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

Plastic pollution processes in rivers

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.

Restoration of seagrass beds in Whangarei Harbour

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.

Clear as mud? Predicting water clarity and light penetration in estuaries

Fine sediment loads delivered to estuaries by rivers are higher today than prior to catchment deforestation due to increased soil erosion. The effects on water clarity, which then impact sensitive estuarine ecosystems, are significant.
