Understanding and supporting the migration of fish through New Zealand's freshwater habitats -
Roto Turf: Aquatic plant ‘life rafts’ in degraded lakes
Research ProjectA team of NIWA freshwater ecologists are researching the use of biodegradable plant mats to help reintroduce native aquatic plants to degraded freshwater lakes in Aotearoa-New Zealand. -
River flow forecasting
Research ProjectNIWA is developing a national river flow forecasting tool for New Zealand that aims to support and strengthen our planning for and response to extreme rainfall events. -
Restoration of aquatic ecosystems
Research ProjectThis project aims to increase our knowledge of aquatic ecosystems and their restoration, and apply this to degraded streams, rivers, lakes and estuaries. -
The Bio-Acoustic Fish Fence
Research ProjectInvestigating the effectiveness of an acoustic bubble-screen in minimising the movement of pest fish -
Ngaa taonga tuku iho o ngaa roto o Tahaaroa
Research ProjectDeveloping the monitoring and evaluation approaches that respond to the hauanga kai aspirations of Ngaati Mahuta -

Future Coasts Aotearoa
Transforming coastal lowland systems threatened by sea-level rise into prosperous communities -
High Frequency Water Quality Monitoring Guidance
Research ProjectA NIWA-led project to support anyone wishing to deploy a water quality sensor in rivers, lakes and estuaries. -
Investigating ecological impacts on freshwater insects from LED streetlight conversions
Research ProjectMany New Zealand cities and towns have switched over to modern LED street lighting. The move will save on operational costs, but little is known what impact artificial streetlights have on flying freshwater insects which are integral to our waterway ecosystems. NIWA investigated the likely impact as part of a four-year MBIE-funded Smart Idea project. -
Effective mitigation systems to manage contaminant losses
Research ProjectNutrients, sediment, and microbial contaminants are mobilized from urban and agricultural landscapes and enter streams, rivers, lakes and estuaries. These contaminants can degrade water quality, ecological health, and cultural values. -
Cultural Keystone Species
Research ProjectA four-year research programme focused on the co-management and restoration of our freshwater taonga species.
