Hunua Quarry Development fast-tracked

"This is the 37th project approved through the Fast-track process," Infrastructure Minister Chris Bishop and Resources Minister Shane Jones say.

Winstone Aggregates lodged its application in March 2026, with approval taking around four months from the appointment of an independent expert panel.

The redevelopment of Hunua Quarry will expand existing quarrying activities to allow Winstone Aggregates to deepen the existing Symonds Hill Pit to access additional high-quality greywacke and enabling a peak production capacity of up to 5.4 million tonnes a year of processed aggregate.
