    New Zealand streamflow depletion model: A tool for sustainable water resource management

    Intense competition for water is putting pressure on the life-giving resource, elevating demand for expert research to improve water management systems.
  • Investigating ecological impacts LED streetlight conversions on freshwater insects 

    Most New Zealand cities and towns have switched over to modern Light-Emitting Diode (LED) street lighting, which provides improved illumination at lower operational cost.
  • Barriers to freshwater fish migration

    Nearly half of New Zealand's river network is partially or fully inaccessible to migratory fish, a new study shows.
