Onerahi can mean "long beach", from ('beach') and ('long' or 'wide'). According to a Māori legend, the place was also called
Onerahirahi. Twin sisters
Reitū and Reipae were being carried on the back of a (
falcon) to Ueoneone, a
Te Rarawa chief they were in love with. Reitū, who was seated to the front, suggested to the falcon that it might be getting tired carrying the both of them. Reipae overheard the remark, took offence and asked the falcon to land, which it did at Onerahi. After dismounting, Reipae was unable to remount the falcon and remained there, naming the place
Onerahirahi, meaning the beach () of quick overhearing (). The land for the town was purchased by
Henry Walton and
William Smellie Graham from
Te Tirarau in the mid-1860s. It had been called Kaiwaka Point, but they renamed it Grahamtown. In 1912 it was renamed
Onerahi to prevent a conflict with
Grahamstown in the
Coromandel. From 1911 to 1933, Onerahi was served by a
branch line railway from the
North Auckland Line known as the
Onerahi Branch. It was built to provide access to a wharf in Onerahi. When coastal shipping declined severely in the 1930s, the railway was closed. Part of its
formation has been retained as a walking track. Whangarei Aerodrome, now
Whangarei Airport, opened at Onerahi in May 1939 and was soon taken over as an
RNZAF training base. It later returned to civilian use, with commercial flights commencing in 1947, and has served Whangārei since. ==Demographics==
