LINZ has established a network of sea level monitoring sites at 18 locations around New Zealand and Antarctica.
The first site was established in March 2007 and the network was completed in July 2010.
With the exception of the Antarctic site, the primary purpose of the network is to upgrade and improve New Zealand's response to tsunami hazards. However, the data generated can also be used for other purposes.
To view plots of the sea level data and for more information on the use of sea level data in a tsunami detection system, visit the GeoNet website.
