Erua was a station on the North Island Main Trunk line,[1] in the Ruapehu District of New Zealand.

To supply timber to the Frankton Junction Railway House Factory, a sawmill NZR opened a forestry block.

[13] To work this block, NZR built a 4.2 km (2.6 mi) siding from Pokaka, which continued to have some use until about 1932.

[14] A tablet lock was added to Karioi Sawmill Co.'s siding between Erua and Pokako in 1930.

[15] There were several other timber companies at Erua, including Wanganui Sash and Door,[12] whose tramway closed in December 1956.
