Located in the Waitaki village of Duntroon, Brewery Hole has both an interesting geological and historical story.
Brewery Hole is an excellent example of karst topography where parts of the local limestone (Otekaike Limestone) have been dissolved away creating an underground drainage system consisting of sinkholes and caves. The local river – the Maerewhenua disappears into sinkholes and travels around 4.5 km underground – and this is what is visible at the sunken cave that is Brewery Hole.
Prior to European settlement, the waters at Brewery Hole were referred to as ‘Waikoakoa’ (happy waters). Historically the water was used by the local blacksmith, and from the 1970s as a water source for the Duntroon Water Scheme (although the town no longer draws its water from the hole).
