The 1902 edition of The Cyclopedia of New Zealand described the station as wooden, with an asphalt platform, goods shed, lamp and luggage rooms, a ladies' room, public waiting room, stationmaster's office and a post office.{{Cite web|url=http://nzetc.victoria.ac.nz/tm/scholarly/tei-Cyc02Cycl-t1-body1-d3-d3-d7.html|title=Ngaruawahia|website=nzetc.victoria.ac.nz|access-date=2 July 2017}} A new station was reported as open in 1915,{{Cite journal|date=24 June 1915|title=Huntly|url=https://paperspast.natlib.govt.nz/periodicals/NZT19150624.2.37|journal=New Zealand Tablet}} though in 1916 the station was reported as "rearranged considerably",{{Cite web|url=https://paperspast.natlib.govt.nz/parliamentary/appendix-to-the-journals-of-the-house-of-representatives/1916/I/1023|title=Appendix to the Journals of the House of Representatives – Railways Statement By the Minister of Railways, The Hon. W. H.
