Te Korowai-o-Te-Tonga Peninsula, also known as South Head and by its former name of the South Kaipara Peninsula, is a long peninsula in the North Island of New Zealand, extending north along the western edge of the Kaipara Harbour for some 35 kilometres (22 mi) from near Helensville to the harbour's mouth. The peninsula was officially renamed in 2013 as part of a Treaty of Waitangi settlement. The name, which is Māori for "The cloak of the south", reflects the peninsula's geographical role in guarding the southern half of the Kaipara Harbour from the Tasman Sea and prevailing westerly winds. The mouth of the Kaipara Harbour separates the peninsula from the larger Pouto Peninsula to the north.
