EDENz provides visitors with access to data from a range of stations monitored by NIWA. This site was created to display data from River Flow and Rainfall sites funded through the Foundation of Research, Science & Technology (FRST) Public Good Science and Technology (PGS&T) Nationally Significant Database program. More recently it has been extended to include data relating to various Sea Level, Air Quality and Climate stations. While some Climate related data is shown on this site, NIWA's core Climate database is accessible from the Climate Database.
There are two types of data shown on this site. The first is near real-time data which has been transferred using a national telemetry network and is unaudited. This data is provisional and cannot be downloaded. The second type of data is archive data which has been reviewed and/or had quality assurance procedures applied. It is now possible to download the archive datasets from sites which are part of the Nationally Significant Database program. Other archive datasets are also available for download where the site owner has provided permission.

The goal of this programme is to provide comprehensive and accessible data as a basis for improved knowledge on New Zealand's climate and freshwater resources.
The programme collects, stores, and disseminates data from national monitoring networks, and comprises two core nationally significant databases:
The data include air temperature, barometric pressure, wind direction, rainfall, lake and river water levels, river flows and sediment loads, and river water quality variables.
A key aspect of the archiving programme is application of stringent quality control procedures ensuring national consistency and providing assurance that data can be confidently used for scientific and planning purposes.
The databases are accessed by other PGS&T research programmes and by a wide spectrum of users, and contributes to the sustainable management of air and freshwater resources and ecosystems, flood control, and education.
The databases are augmented by over $1m of funding from the hydro-electricity industry and by data provided by regional councils.
