The Karangahake Company determine to erect a stamper battery at Battery Flat. They talk about it from early 1875, but it is not established until mid 1876.

Results are very poor, and crushing is suspended late August.

In 1882 the Karangahake Battery becomes Hauraki Battery, then the Ivanhoe Battery in 1887.

14 years of unsuccessful to marginally successful operation comes to an end when the Ivanhoe Battery is sold for removal to Puriri in 1890.

A lack of photographs of this battery has added to the relative invisibility of this battery’s contribution to the early history of Karangahake.
