Factsheet: (NEMS) National Environmental Monitoring Standards

The National Environmental Monitoring Standards steering group (NEMS) has prepared a series of environmental monitoring standards with support from the Regional Chief Executive Officers (RCEO) and the Ministry for the Environment (MFE). The development of these standards was led by regional and unitary councils from across New Zealand, in partnership with the  electricity generation industry  and the National Institute for Water and Atmospheric Research Ltd (NIWA). 


These documents prescribe technical standards, methods and other requirements associated with the continuous monitoring of a number of environmental parameters. The agencies that developed these standards are responsible for the majority of hydrological and continuous environmental related measurements within New Zealand. It is recommended that these standards are adopted throughout New Zealand and that all data collected is also  processed and quality coded appropriately. The degree of rigour in which the standard is applied, will depend on the quality of data sought.

These documents have been subject to continuous stakeholder review. Appropriate changes have been made and are now amended as Final versions except where stated otherwise. The final versions have been ratified by RMG representatives and crown copyright is invoked.

A review will be conducted within one year of release. They will be reviewed thereafter, once every two years. Following any changes being made as a result of review, version numbers will be updated on the cover of the document. The document control register gives the date and a summary of the changes made.
