Waimiha was a flag station on the North Island Main Trunk line, in the Ruapehu District of New Zealand, serving the small village of Waimiha in the Ōngarue valley.

[1][2][3] Its site covered 6 acres (2.4 ha),[4] with a shelter shed, platform, cart approach and loading bank.

[6] The rails reached Waimiha about Christmas 1900[7] and by 28 May 1901 it was reported that goods for workmen were being carried on the ballast trains.

A railway worker's cottage was in place by 1902 and a house for second porter was mentioned in 1912.

[5] In 1921 Rangataua Timber Co advertised for tenders for a mile of tramway.
