Half Moon Bay, is a suburb of East Auckland, New Zealand, lying immediately south of Bucklands Beach.

[4][5] Part of the shoreline of Half Moon Bay is a lava flow that was formed approximately 10,000 during the eruption of Maungarei.

Tāiki settled with his followers along the eastern shores of the Tāmaki River, alongside the descendants of Huiārangi of the early iwi Te Tini ō Maruiwi.

[13] From the 1790s, Te Rangitāwhia was the paramount chief of Ngāi Tai, whose principal residences were at Waiārohia and to the south at Ōhuiarangi / Pigeon Mountain.

[11] After the village was attacked by Kapetaua of the related iwi Te Patukirikiri, Ngāi Tai built a smaller pā on the mountain.

[10] During the Musket Wars in the 1820s, the Half Moon Bay area was evacuated, and the lands became tapu to Ngāi Tai due to the events of the conflict.

[14][15] Most members of Ngāi Tai fled to the Waikato for temporary refuge during this time, and when English missionary William Thomas Fairburn visited the area in 1833, it was mostly unoccupied.

[19][16] In 1847, Howick was established as a defensive outpost for Auckland, by fencibles (retired British Army soldiers) and their families.

[22] In 1949, the King George V Memorial Health Camp was opened, as a location for children to recuperate from illness.

[22] In 1967, Unit Subdividisons Ltd began subdividing the area, adopting the name Half Moon Bay.

[26] The Bucklands Beach Yacht Club moved to Half Moon Bay, and opened new clubrooms in 1988.
