About
The Farewell Spit Lighthouse is located at the end of New Zealand's longest sand spit in Golden Bay / Mohua, near the northern tip of the South Island. It guides vessels entering Cook Strait from the west and south. The LED rotating beacon flashes white or red, once every 15 seconds. It has a range of 19 nautical miles (35 km; 22 mi). Red is shown to warn approaching vessels of extensive shoaling. Standing 27 metres (89 ft) tall, the tower needs to be taller than the support structures of most lighthouses built on cliffs or headlands, because the sand foundations it is built upon are almost at sea level. The tower is constructed of an open steel lattice to withstand abrasive sand and salt-laden winds.
