Nettlebed Cave is a limestone cave located in the Mount Arthur region of the northwest South Island of New Zealand.
It is the deepest cave system in the southern hemisphere, dropping 889 metres below its upper entrance (Blizzard Pot) to its lower exit (Pearse Resurgence). Its 24 kilometres of cave passages make it one of New Zealand's longest caves.
Nettlebed Cave was first explored by cavers in 1969 through the dry overflow passage of a large spring pouring into the Pearse River. By 1973 1.3 kilometres of passages had been mapped. It was not until 1979 that a flowstone squeeze known as the Hinkle-horn-honking-holes was passed, making further explorations possible. Five successive Christmas expeditions (1979-80 through 1983-84) utilizing an underground camp at Salvation Hall led to the exploration and mapping of a further 20 kilometers.
In 1986 another cave (Blizzard Pot) was connected with Nettlebed Cave, providing an upper entrance to the system.
On 21 March 2007, a team of international cave divers set a new record by diving to a depth of 177m (more than 580 feet below ground level) in the Pearse Resurgence.1
