The RV Tangaroa is assisting in New Zealand’s largest ever deployment of seafloor earthquake recording instruments in a bid to learn more about the earthquake behaviour of the tectonic plates beneath the east coast of the North Island.

The 2016 Kaikōura Earthquake has shown that more than 100 million dumptrucks of mud and sand flow through the Kaikōura Canyon every 140 years, scientists say.

The Tangaroa assisted in New Zealand’s largest ever deployment of seafloor earthquake recording instruments in a bid to learn more about the earthquake behaviour of the tectonic plates beneath the east coast of the North Island.

An ambitious scientific expedition involving 30 scientists from around the world leaves Perth next week bound for the East Coast of the North Island.

A tsunami reporting station situated in the Pacific Ocean that is currently off line is to be upgraded in a joint operation involving New Zealand and United States government agencies.

NIWA vessel RV Tangaroa visted Kaikōura in September 2017 to investigate the impacts of the earthquake in the coastal zone, which includes effects on rocky reef habitats and communities, pāua fishery and Hector’s dolphins.

The term “joined-up government” was coined in the late 1990s to describe the coordination modern governments need to deal with large problems.

Autumn and winter rain caused damaging floods and slips across New Zealand, yet again. Susan Pepperell investigates the nation's evolving skill in avoiding and coping with water.

It is well known that earthquakes can trigger tsunami but they can also be caused by landslides – with devastating effects.

Since the end of June, a barge has been stationed just off Wellington’s Miramar Peninsula drilling into the seabed to find an alternative water source for the city.

For the past year, NIWA’s meteorologists have been on call to provide real-time, comprehensive information about weather patterns that may accelerate a fire.

NIWA scientists have found signs of recovery in the Kaikōura Canyon seabed, 10 months after powerful submarine landslides triggered by the November earthquake wiped out organisms living in and on the seabed.
