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.[1] It is on a sandspit that adjoins Tāwharanui Peninsula and separates Whangateau Harbour from Ōmaha Bay. The nearest sizeable town is Warkworth which is situated 16.8 km south west of Ōmaha.[1]
Ōmaha was a Marutūāhu settlement until 1841, when it was bought by the Crown. Early European settlement took place at Sandspit.
The Māori name Maori: Ōmaha means 'bountiful food' or 'great resources'. Nearby Leigh was historically named Ōmaha by Māori, and Ōmaha Beach was called Mangatawhiri by Ngāti Manuhiri.[2]
Omaha saw growth during the 1970s when a bridge to Omaha was constructed by Broadlands Properties, who then subdivided the land and built housing.[3]
To prevent erosion a wooden barrier was constructed. Despite these efforts on the 19th of July, 1978 a strong storm destroyed the barrier and caused damage to several beach front properties. To solve the issue of erosion and flooding with high tides three groynes were constructed to divert currents from Omaha. Alongside these groynes the harbour would be dredged with sand taken to the beach.[3]
Following the work to protect the foreshore more building permits were permitted; however, most came with a caveat requiring them to be raised slightly above the ground.[3]
The sandspit of Ōmaha was formed during the last glacial period, approximately 5000 to 6000 years BP. The beach sediment composition is over 70% quartz sand, which gifted Ōmaha the natural "white" appearance. There are three artificial groynes had been placed at northern part of the sandspit, to accumulate sediment from longshore drift. Local council in last two decades had been placing various groups of plant to stabilize the dunes, including Spinifex, pingao, iceplant and marram grass.
Ōmaha Spit has also been identified by the Department of Conservation as a "significant breeding site for the endangered New Zealand dotterel.[4] As a result, The Omaha Shorebird Protection Trust was established in 2009 to monitor the dotterel population at Ōmaha.[5] Fundraising of $162,000 by the Trust saw construction of a predator-proof fence completed in August 2012 helping to protect the birds, their chicks and eggs from predation by cats, rats, stoats, wessels and hedgehogs.[6]
In the early 1980s the population less than 100. By the start of the 1990s it had increased to 300.[3]
