The abundance and diversity of life in our rivers, lakes and estuaries is the ultimate indicator of the health and wellbeing of our aquatic ecosystems. NIWA is helping to ensure that New Zealand’s unique and iconic freshwater species are healthy, abundant and thriving.
New Zealanders are increasingly demanding better information on how much water is in our rivers and groundwater aquifers, how that has changed over time and how it might change in the future.
This programme will increase our understanding of the hydrological cycle: the quantity of freshwater in our rivers and groundwater systems, where that water came from and how long it took to get there.
Understanding and predicting the sources of contaminants, developing technologies to clean up the sources, and understanding the consequences of water quality degradation for aquatic ecosystems and human use of waterways.
The goal of the Freshwater Biosecurity programme is to support the New Zealand Biosecurity Strategy by reducing the risk of new freshwater invasive species incursions and establishment, minimising the adverse impacts of established populations of these species, and developing methods for reducing or eradicating those populations.
