The station was planned in 1879[5] and opened in 1880 at the same time the NIMT was extended to Te Awamutu, though it wasn't mentioned in the press until postal contracts were being let in 1881.[6] By 1884 Ngaroto had a 4th class station, passenger platform, cart approach, 60 ft (18 m) x 30 ft (9.1 m) goods shed, loading bank, stationmaster's house and urinals. From 1883 to 1917 there was a Post Office at the station. There were cattle yards by 1897 and sheep yards by 1911. A crossing loop could hold 41 wagons. There was a proposal to close the station in 1886.[5] It was staffed until 1887,[7] when a ganger took on running the post office.[5] In the early years it was a vital part of local farm transport.[8]
Apart from electrification, the only significant work since then seems to have been in 1928, when a lengthy embankment and raised bridge over the Mangapiko Stream lifted the line about 5 ft (1.5 m), to ease the climb from Te Awamutu to Ngaroto.[9]
