Rangiahua nearly became New Zealand's most northern railway terminus. In 1923, the Okaihau Branch, a branch line from Otiria on the North Auckland Line, was opened to Okaihau and work began on an extension to the Hokianga Harbour and Kaitaia. There were disputes over the viability of the line, but a compromise was reached that would have established Rangiahua as the terminus. Work progressed slowly throughout the 1920s and was abandoned during the Great Depression, even though the line was nearly complete - New Zealand's northernmost railway tunnel had been made and Rangiahua's railway yard and platform had been built. In 1936, a review was conducted into the future of the line, and the decision was that no extension beyond Rangiahua would be economic, and that the section from Okaihau to Rangiahua would not be viable. The abandoned track and associated equipment was salvaged for use elsewhere, and today State Highway 1 runs where the station used to be, with the platform to the east and a loading bank to the west.
