The Ellis Basin cave system was first explored by cavers in the 1960s. In April 2010, the cave system was found to be deeper than the nearby Nettlebed Cave, making it the deepest known cave in the Southern hemisphere.[1] It has been explored to a depth of 1,024 m (3,360 ft), and its 33.4 km (20.8 mi) of cave passages make it New Zealand's second longest.[2]
