Tāwharanui Peninsula is a finger of land projecting into the Hauraki Gulf from the east coast of the much larger North Auckland Peninsula of New Zealand. It separates Omaha Bay to the north from Kawau Bay and Kawau Island to the south. The nearest sizable town is Warkworth. Tāwharanui Regional Park covers 588 hectares of the peninsula's land and Tāwharanui Marine Reserve covers the northern coastal sea. Both are administered by Auckland Council which also owns the regional park. Geologically the peninsula consists of Waitemata Sandstone on top of folded and uplifted greywacke.
History
lived in the area for over 800 years. The Māori name Tāwhara-nui refers to "the abundant bracts of the kiekie vine". Until the 1870s, the park was occupied by a small hapū of the Te Kawerau people called Ngati Raupo. The people lived mainly around the catchment of the Mangatawhiri Stream. A significant pā, Oponui, was near the entrance to the park and above the stream outlet was Pa-hi. Tāwharanui provided a large variety of marine and forest resources. This was celebrated in the saying, "He wha tāwhara ki uta; he kiko tamure ki tai" – "The flowering bracts of the kiekie on the land, the flesh of the snapper in the sea". Waikokowai provided a valued source of kokowai or red ochre, which was used for decorative and ceremonial purposes. Tāwharanui was sold by the Māori owners in 1873–1877 and developed as a farm by the Martin, Jones and Young families. Kauri timber was milled and manuka cut for firewood for many years. Shingle was extracted for a hundred years, creating the Jones Bay Lagoon. Nine vessels were wrecked on the Tāwharanui coastline between 1871 and 1978. Anchor Bay is named after the anchor of the Phoenix, wrecked in 1879. The Auckland Regional Authority, forerunner of the Auckland Council, purchased the parkland from the Georgetti family in 1973.

Regional park
The park combines a "mainland island" sanctuary for the conservation of native plants and animals with farmland and public recreation areas. The park is mostly grazed pasture with manuka scattered throughout and patches of coastal forest. The most significant area of coastal forest is in the central eastern part of the park where kauri and rimu dominate the ridges, with puriri, taraire, tawa and, less often, rewarewa and nikau in the valleys. Elsewhere there are totara, kahikatea, pohutukawa, cabbage trees, karaka and New Zealand flax. The mainland island was created by the construction of a 2.5 km pest-proof fence across the peninsula in 2004. This was followed by an aerial drop of poison later in 2004 which eliminated black rats, brown rats, feral cats, possums, weasels, stoats and ferrets. Introduced pests remaining in the sanctuary are mice, rabbits and hedgehogs. The Tawharanui Open Sanctuary Society Inc. assists Auckland Council with the sanctuary by fundraising and volunteer work. Sixteen species of native land birds and 15 species of native coastal birds have been recorded in the park. Wetland birds include the Australasian bittern, spotless crake and fernbird. Coastal birds include the New Zealand dotterel, blue reef heron and variable oystercatcher.
