NIWA is a key contributor to the National Science Challenge on Biological Heritage hosted by Landcare Research. The challenge is to “Reverse the decline of New Zealand’s biological heritage, through a national partnership to deliver a step change in research innovation, globally leading technologies and community and sector action” and covers both terrestrial and freshwater environments.
Our Land and Water is the science challenge that addresses conflicts and tradeoffs between the needs for agricultural productivity and environmental health and protection. NIWA plays a big role in Our Land and Water, particularly in biophysical science and tool development.

The naturally high organic content and slightly acidic nature of peat lakes gives them uniqueness and great ecological value but it also makes them challenging ecosystems to rehabilitate once degraded.
Fine sediment is New Zealand’s most widespread water contaminant, degrading ecosystems, infilling dams and reservoirs and impairing recreational, cultural and aesthetic values in our rivers, estuaries and coastal seas.
The ANZECC water quality guidelines are used extensively throughout New Zealand in managing water quality and potential effects of discharges.
