Manukapua Island, also known as Sand Island or Big Sand Island, is an island located in the Kaipara Harbour in the Auckland Region, New Zealand, near TÃÂpora on the Okahukura Peninsula.
Manukapua Island is located in the central Kaipara Harbour, at the point where the Kaipara Entrance meets the Otamatea Channel and the Tauhoa Channel. The area is dominated by sand dunes and wetlands. The island is accessible by foot.
Much of the island is located within the Manukapua Government Purpose (Wildlife Management) Reserve, previously known as the Tapora Government Purpose (Wildlife Management) Reserve, and the island is a part of the Manukapua Island and Okahukura Sequence biodiversity focus area, It is an important nesting area for the New Zealand dotterel and New Zealand fairy tern, and is a roosting area for migratory birds.
NgÃÂti WhÃÂtua traditions tell of the MÃÂhuhu-ki-te-rangi migratory waka arriving at the Kaipara Harbour. Some of the crew members, including Rongomai, Mawete and Po, settled at TÃÂporapora, with the descendants of Toi, who already lived in the area. Different sections of the island (then a peninsula) were named TÃÂporapora, a name which references a place in the homeland of the MÃÂhuhu-ki-te-rangi waka, and Manukapua, a name which means "Cloud of Birds". TÃÂporapora was a fertile sandy land that gradually eroded west of the Okahukura Peninsula, of which Manukapua Island is a remnant. The island is seen as the birthplace of NgÃÂti WhÃÂtua, and has spiritual importance to the hapà « Te Uri-o-Hau.
Since the 14th century, the island has significantly reduced in size due to weather events such as tsunami, with oral traditions describing the island as extending far into the Kaipara Harbour mouth.
In 2013, a fire destroyed all vegetation on the island. In 2019, the Department of Conservation funded a widescale restoration project on the island, where of gorse and pampas that had grown since the fire was cleared, and replaced by 13,000 native trees.
