Ngahere is located on the south bank of the Grey River, and State Highway 7 and the Stillwater - Westport Line (SWL) railway pass through the village. The railway reached Ngahere when an extension was built from Brunner on 1 August 1889, and it was the line's terminus until a further section to Ahaura was opened on 14 February 1890. On 1 August 1910, Ngahere became a railway junction when the Blackball Branch was opened, and this branch line operated until a flood in 1966 destroyed its bridge across the Grey River. The branch was formally closed on 21 February 1966. The next year, passenger trains through Ngahere on the SWL were cancelled; since this time, freight trains of coal have been the predominant traffic through Ngahere.
