Tāwharanui Regional Park

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 Ōmaha 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.Tāwharanui Marine Park was established offshore of the peninsula in 1981 as New Zealand's first Marine Protected Area. The marine park was replaced by Tāwharanui Marine Reserve in September 2011.North Island brown kiwi was reintroduced into the area.

The Smelting House ruins on Kawau Island, New Zealand, belong to the copper mine established in 1844. As there were problems with combustion of the copper ore during the sea voyage to Wales or Australia, tenders were called in 1848 for the erection of a copper mine smelter. The Auckland architect Walter Robertson designed a simple building completely built of Waitematā sandstone. Opened in July 1849, it was New Zealand's first smelting house. The smelter was no longer functioning in September 1855, and shortly after that, the mine closed altogether.After the Battle of Rangiriri, which was part of the Invasion of the Waikato, the building briefly housed the 183 Māori prisoners taken in that battle. Guarded by just six wardens, they escaped in September 1864 and eventually returned to the Waikato.The smelter site was purchased as a reserve in 1977. The ruins were registered by the New Zealand Historic Places Trust (now called Heritage New Zealand) on 24 November 1983 with registration number 10. The ruins have a category I listing. As of 2015, about 50% of the walls remain standing on three sides of the building. The site can be visited by boat only.

Kawau Island is in the Hauraki Gulf, close to the north-eastern coast of the North Island of New Zealand. At its closest point it lies 1.4 km (0.87 mi) off the coast of the Northland Peninsula, just south of Tāwharanui Peninsula, and about 8 km (5.0 mi) by sea journey from Sandspit Wharf, and shelters Kawau Bay to the north-east of Warkworth. It is 40 km (25 mi) north of Auckland. Mansion House in the Kawau Island Historic Reserve is an important historic tourist attraction. Almost every property on the Island relies on direct access to the sea. There are only two short roads serving settlements at Schoolhouse Bay and South Cove, and most residents have private wharves for access to their front door steps. The island is named after the Māori word for the shag (cormorant) bird.A regular ferry service operates to the island from Sandspit Wharf on the mainland, as do water taxi services.

Tāwharanui Marine Reserve is a marine reserve covering an area of 394 hectares (970 acres) in the Hauraki Gulf, offshore from the Tāwharanui Peninsula in the Auckland Region of New Zealand's North Island. It was established in 2011 and is administered by the Department of Conservation.

Mansion House on Kawau Island, New Zealand, is a house that was owned by Sir George Grey from 1862 to 1888. Built in 1845 as the house for the manager of a copper mine on the island, it was extended significantly by Grey during his ownership. Mansion House is a heritage listed building. It is open to the public as part of the Kawau Island Historic Reserve administered by the Department of Conservation.

Ōmaha is a small beach town on Ōmaha Bay in the Auckland Region, in the north of New Zealand. It is located 74.7 km north of central Auckland.

Takangaroa Island (formerly known as Goat Island) is one of the two Mayne Islands located near Kawau Island, in New Zealand's Hauraki Gulf. It is approximately 6 hectares (15 acres) in size.Its name is Māori, and means "The Long Casting of the Net". Nearby Rabbit Island is known as Takangariki, "The Short Casting of the Net", and two rocky reefs between them are considered to be the buoys of the net.The island was known as Goat Island until 1971, when the name was legally changed to the Māori name in order to prevent confusion with the popular marine reserve.During the late 19th century, it was owned by George Grey, the former Governor-General of New Zealand. The island is now privately owned, and is a wildlife sanctuary, meaning that no dogs, cats or guns are allowed.

Ti Point is an area off Omaha Beach in the small New Zealand village of Leigh, located in the Rodney District. Ti Point is situated very close to Leigh and Goat Island, and is just over one hour drive north of Auckland. It is used for fishing, boating, hiking, rock climbing and yachting, and is under governance of the Rodney District Council, just north of Whangateau.

The Pumphouse ruins on Kawau Island, New Zealand, belong to the copper mine established in 1844. The mine had ongoing problems, including legal, mismanagement, and flooding. To address the latter issue, a pumphouse was built in 1854. The ruins were registered by the New Zealand Historic Places Trust (now called Heritage New Zealand) on 23 June 1983 with registration number 9. The ruins have a category I listing.

Baddeleys Beach and Campbells Beach are a contiguous settlement on adjacent beaches on the southern side of Tāwharanui Peninsula in the Auckland Region of New Zealand. The beaches are on Millon Bay, which is a part of Kawau Bay.The land around Millon Bay was originally covered by kauri and other native trees, which were the focus for logging by early European settlers. Once the land was cleared it was used for dairy farming by the Baddeley and Campbell families. In the mid-1960s, with farming proving financially marginal, blocks were sold off for the building of baches. These subsequently were upgraded to or replaced by permanent dwellings.Baddeleys Beach Reserve and Campbells Beach Reserve give public access to the beaches at each end of the settlement and provide basic amenities.

The Whangateau Harbour is a natural harbour in New Zealand. It is a sandspit estuary, located on the north-eastern coast of the Auckland Region north-east of Matakana, and empties into the Hauraki Gulf. Due to the harbour's high quality water and dense shellfish beds (primarily pipi), the harbour is a popular spot for shellfish gathering.

Mathesons Bay (Māori: Te Kohuroa; officially Te Kohuroa / Mathesons Bay) is a small beach in the Rodney district of the Auckland Region of New Zealand. It is 21 kilometres north-east of Warkworth, near the small community of Leigh. It comprises mainly holiday homes, with a small number of permanent residents.
