Land Air and Water Aotearoa - LAWA
A New Zealand first, LAWA displays water quality state and trend information for more than 1100 freshwater monitoring sites, giving you access to all of the country’s water quality monitoring in one place and in an easy- to- understand format.
What indicators does LAWA display
Regional councils measure a range of indicators when assessing water quality. The most common are bacteria, nitrogen, phosphorous, water clarity and acidity.
LAWA collects this information from around New Zealand and allows users to see where a river or catchment sits in comparison to others for each parameter and indicates whether things are improving, degrading or remaining stable.

Water quality science is complex as many factors affect river health. LAWA brings these together to indicate the health of waterways and to help us better understand what’s going on in our rivers at a local, regional, and national level.
Working together to maintain and restore waterway health
There is no single solution for achieving better water quality. Success is the responsibility of everyone using freshwater. Long-term partnerships between stakeholders and others interested are the best way to drive sustainable changes.
LAWA is a collaborative effort between regional councils, the Cawthron Institute, Massey University and the Ministry for the Environment. These organisations share a desire to see New Zealand rivers maintained or improved.
LAWA has been financially supported by the Tindall Foundation, which wants to see New Zealanders better connected to what’s going on in their rivers.
To give people confidence about the accuracy of the data LAWA displays, New Zealand’s largest independent science organisation, the Cawthron Institute, has partnered with the councils and MfE to validate the way the data is collected, processed, and analysed.
