Hapuku (Polyprion oxygeneios) is known by the Maori name in the north, but groper is preferred in the south. This is a large, heavy, deep-sea fish closely related to the bass. It lurks in caverns and around reefs in deep water and is obtained only by line fishing. Some specimens attain a length of 5 ft and a weight of over 100 lb. Owing to its large size this fish is sold as steaks cut transversely between sections of the vertebra. It is a popular food fish throughout New Zealand.
