New Zealands' worst mining distaster happened on 26 March 1896 at Brunner on the West Coast, killing 65 men.
An historic memorial site now stands on the location of the disaster.
The memorial site sits on the side of State Highway 7 on either side of the Grey River, a suspension bridge joining each side.
The entrance starts at the top of a 65-step memorial and mining remnants can be viewed.
The Brunner Mine Site was a big producer of coal and coal by-products such as coke and firebricks.
Walk through the industrial ruins and see some of the last remaining beehive coke ovens.
