The SS Rotomahana, launched in 1876, holds the distinction of being the first iron vessel built in Auckland. As a harbour steamer, she was constructed by Fraser & Tinne and was notable for being launched just 28 minutes ahead of a smaller iron ship, marking a significant milestone in New Zealand shipbuilding. The vessel's name, Rotomahana, was shared with other ships of the era, likely inspired by the fame of the Pink and White Terraces and the visit of the Duke of Edinburgh in 1870. Designed for passenger service, Rotomahana primarily operated along the Auckland–Thames route, covering approximately 50 miles (80 km). She served her original builders until 1888, during which time she displayed reliable performance. In 1879, she underwent re-engining after overheating issues, and a comprehensive refit in 1891 saw her boiler repositioned, the pressure increased, and her masts reduced from three to two, enhancing her efficiency and stability. Ownership changed multiple times during her service life. After being sold by Fraser & Tinne in 1888 to M.T. Clayton, she was operated by the New Zealand Insurance Co. until 1890, when she was sold to Captain Worsp and subsequently transferred to the Northern Steamship Company. Rotomahana continued passenger routes around Thames and other Hauraki Gulf destinations, including Port Fitzroy, Okupu, and Tryphena on Great Barrier Island, until 1898, when she was replaced by the larger Wakatere and shifted to the Coromandel run. Her most notable incident occurred on 28 May 1911, when she ran aground near Motuihe Island in heavy fog but was refloated with no damage. Her service concluded around October 1914, after which she was surveyed, laid up, and repurposed for oil storage. Eventually, she was dismantled, and in 1924, McCallum Bros beached her on Pakihi Island for use as a wharf. Remnants of her hull remained visible as late as 1999, marking her as a significant vessel in New Zealand maritime history.
