From KAREN wiki

The main goal of the PlanetLab NZ project is to enable network research groups from New Zealand universities to access PlanetLab. PlanetLab is the global experimental networking facility, designed for conducting cutting-edge research on current and future network technologies, such as Next Generation Networks (NGNs), Next Generation Internet (NGI), Future Internet, etc. Access to PlanetLab totally depends on KAREN.
