In between Greymouth and Punakaiki is this monument on top of a hill next to the main highway. The Strongman Mine was an underground coal mine north of Greymouth of New Zealand's west coast of the South Island that operated from 1938 until 2003.
On 19th January 1967 a gas explosion in the mine killed 19 miners. In 1994 the original mine was replaced by the Strongman 2 mine further up the Nine Mile Valley. This mine eventually closed in 2003.
The monument honours those who were killed in the disaster and acknowledges the 65 years of mining in the area.
