  Groundwater science protecting New Zealand’s drinking water

  Forty per cent of New Zealanders rely on groundwater for drinking water. This comes with challenges, as groundwater is slow-moving, feeds many environments such as estuaries and can take decades to clean once it’s contaminated.

  Landscape-scale control of possums

  Introduced in the mid 1800s by settlers looking to start a trade in possum fur, the Australian common brushtail possum faced no natural predators and quickly got out of control: by the mid-1980s it was estimated there were 60-70 million of them in New Zealand

  Taking the sting out of wood wasps

  Since the early 1960s, science has played a key role in protecting New Zealand’s forests from pests and pathogens, ensuring they remain healthy and productive. This work has led to the development of early warning systems to improve surveillance and disease forecasting and has helped forest owners build evidence based control strategies.
