Since the end of June, a barge has been stationed just off Wellington’s Miramar Peninsula drilling into the seabed to find an alternative water source for the city.

A sophisticated buoy has been deployed in Wellington Harbour to “phone home” information about currents, waves and water quality in the harbour.

NIWA, supported by DairyNZ, are asking anyone who has planted along stream banks to take a short survey.

NIWA is undertaking a five-year nationwide study to find out how different approaches to riparian planting influence water quality improvements and to provide better guidance to the people and groups undertaking stream restoration.

A buoy with the ability to “phone home” has been deployed in Wellington Harbour today to monitor currents, waves and water quality in the harbour.

Local hapū and NIWA are working together to find out more about juvenile freshwater eels or tuna in streams connecting to the Wairua River in the Wairoa catchment in Northland.

There’s another way of measuring the health of rivers – the health of invertebrate populations that need them, says John Quinn, NIWA Chief Scientist, Freshwater
and Estuaries.

Erica Williams' story starts with the website of Moerewa School, where pupil Tyra-Lee explains her connection to a very special place in her small Far North town.

The government has released the ‘Clean Water’ package of proposed reforms, aimed at making more of our rivers swimmable. But how is ‘swimmable’ to be measured, and do these measures stack up?

NIWA's Freshwater and Estuaries Chief Scientist Dr John Quinn believes the dairy industry has been responsive in the tools it has adopted to reduce its impact on waterways.

NIWA is leading a new six-year research project that seeks to increase our understanding of piharau/kanakana/lamprey, using Mātauranga Māori, social science and biophysical science approaches.
