Abstract:
The Whitford Quarry, located some 6km south of the Beachlands settlement in East Auckland, is operated by Fulton Hogan Ltd. Resource primarily in the form of 'greywacke' rock, is actively being extracted from the quarry, crushed and sold as aggregate. The quarry is located in close proximity to a large fault (Waikopua) and has overlying younger sediments that mantle the resource rock.
