Casal2 is an advanced software package developed by NIWA for modelling the population dynamics of marine species.

Storm-tide red alerts are the highest high tide (also known as king tides) dates that Emergency Managers and Coastal Hazard Managers should write in their diaries and keep an eye on adverse weather (low barometric pressure, onshore winds), river levels and sea conditions (waves and swell). This page shows the 2023 dates of the highest high-tide "red alert" dates, and the lowest high-tide dates.

To get the most benefit from a fish stock in the long term, we need to maximise our yield without damaging the fish population we rely on.

NIWA is active in a broad range of eDNA topics and can provide expert advice on applications and expected outcomes. We welcome inquiries into our services and can assist with experimental design.

NIWA has world-class expertise in marine macroalgae and extensive research on various aspects of seaweed ecology, growth and taxonomy.
