[4] It was called Hūnua until 7 January 1912 and, though it didn't appear in the 1875 timetable,[5] Hunua was described as a small wayside station on the line's opening day.

[6] The station was first listed in the December 1875 timetable, being served by 2 trains a day, taking 92 minutes for the 21 mi (34 km) from Auckland.

[8] Hunua opened on 20 May 1875, as part of the Auckland and Mercer Railway on 20 May 1875, built by Brogden & Co,[9] when it was extended from Penrose.

[10] A limited service may have started earlier, as Brogden & Sons ran excursion trains to Drury in October 1874.

[13] By 1884 there was a passenger platform with cart approach and a loading bank, and in 1894 there was a petition for a goods shed to be built.
