Matakana Island Click for Map of Matakana Island is located in Tauranga Harbour in the Bay of Plenty, North Island, New Zealand. The Island is New Zealands only âraised sand barrier islandâ and is also classed as a nationally significant geological site.
Beach Sediments can range from silt, sand, gravel to boulders. Most sand has its origins from rocks on the land. The sand at Muriwai is mainly black iron sand (also known as Titomagnetite). This sand originates from the volcanoes of the Central North Island and Mount Taranaki on the West Coast. Rivers from these mountainous regions have eroded volcanic material and carried sediment to the sea. From there longshore drift has transported the black sand up the coast and deposited on beaches.
