Climate change means more intense storm systems are on their way. Science can’t stop it raining, but it can help communities prepare for the worst and plan for the future.

Stacy Mohan looks at how the shockwaves from a remote Tongan island rippled through NIWA’s research community.

Mia Blyth catches up with a marine biologist hunting for ocean ghosts.

New findings from the record-breaking Tongan volcanic eruption are “surprising and unexpected."

A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought. This will be the final update of the Hotspot Watch for this season. Weekly Hotspot Watch updates will resume in the spring.

New Zealand has just over 50 native freshwater fish species. Of these, 85 % are endemic and 75 % are deemed to be at risk of decline or are threatened.
