Research

This project aims to increase our knowledge of aquatic ecosystems and their restoration, and apply this to degraded streams, rivers, lakes and estuaries.

Observations of a Pacific atoll mangrove forest by a NIWA-led research team suggests mangrove systems on oceanic atolls may lose the race to keep pace with sea-level rise.

Te Nehenehenui (previously Maniapoto Māori Trust board) and NIWA are working collaboratively to support Ngāti Maniapoto whānau to reconnect with and participate in the assessment of their freshwater according to their values.

Excessive nutrient input (eutrophication) threatens many New Zealand estuaries causing ecological problems, such as algal blooms and poor physical and chemical conditions for estuarine life.

NIWA is looking for people who have had a long association with the Hauraki Gulf or Marlborough Sounds to help them with a research project on juvenile fish habitats.

NIWA has developed an Urban Stormwater Contaminant (USC) model to enable urban planners to predict sedimentation and heavy metal accumulation in estuaries and identify problem areas in order to target mitigation measures.
