The New Zealand rock oyster grows from the high to the mid intertidal zones while the pacific oyster grows from the mid intertidal zone down. When oyster farmers changed (in the 70's) from NZ rock oyster to the pacific oyster they needed to move their racks out further.
These are NZ Rock oysters in the High intertidal zone.
