Rangiahua is a small locality near the Hokianga Harbour in the Northland Region of New Zealand.

Rangiahua is part of the Omahuta Forest-Horeke statistical area, which covers the upper Hokianga Harbour.

A report in 1931 concluded that the new line would not be economic and that the interest charge on borrowing money for its completion would increase the branch's operating loss.

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.

There is a Maori Cemetery here, situated near the New Zealand State Highway 1, which houses the grave of a Commonwealth casualty from World War I; Rifleman John Muriwai of the New Zealand forces contracted measles and pneumonia and died at Trentham Military Camp on 28 June 1915.
