Millbrook Quarry

Rock from the large Millbrook Quarry, at Whangaripo Valley Road, has served the Rodney District for over 50 years. 

Millbrook quarries is a 50/50 joint venture with Holcim NZ Ltd, a major cement manufacturer, aggregate, and ready mix concrete supplier. Also known as Wharehine’s Whangaripo Quarry, the Millbrook Quarry site has been part of the Wharehine Group since 1955.

The fully functioning quarry covers over 240 hectares and has the potential to be quarried for many decades to come. Aggregate from this quarry is popular as a concrete chip destined for use in tunnels and bridges, roading projects and diverse concrete structures, from bridges to Takapuna apartment towers, local school playgrounds to the lining of the Johnstone’s Hill Tunnels.
