The Kaitorete Spit in New Zealand is 30km long. Its formation dates back a long time. New Zealand formed 26 million years ago when two tectonic plates collided, forcing the crust up into mountains and volcanoes. Two million years ago New Zealand experienced an ice age and the land was covered by glaciers. When the ice melted 12,000 years ago it left behind thick deposits of glacial drift, which now form most of New Zealand鈥檚 coastline. The coast is continually shaped by longshore drift into beaches and spits.
