Hapuku


Hapuku

Hāpuku is New Zealand's premier deepwater table fish — a large, reef-hugging wreckfish found around the entire coastline. Once catchable from shore in places like Lottin Point, increasing pressure has pushed most fish into 200–400m of water.

The reward for getting gear down there is a fish that regularly tops 20–30kg and occasionally exceeds 60kg.

Scientific Name: Polyprion oxygeneios

Also known as Groper, hapuka, whapuku, 'puka


Physical Characteristics:
  • Grey-brown body with a silvery-white belly; juveniles are noticeably blue before transitioning to adult colouration around 50cm.
  • Large, square-shaped tail; protruding lower jaw; very large eyes adapted for hunting in low-light, deep-water conditions.
  • Ten dorsal spines along the back, rounded anal and pectoral fins — a stocky, powerful build throughout.
  • Most fish caught run 20–30kg; the NZ record stands at 68kg (Hawke's Bay, 2005), with unverified reports of fish over 70kg off the Coromandel.

What to know

Habitat Distribution

  • Native to New Zealand waters; found around the entire coastline from the far north to the deep south, including offshore banks and islands.
  • Adults hold tight to reef structure — pinnacles, drop-offs, caves, and rough foul bottom — typically in 60–400m, though the range extends to 800m.
  • Juveniles are pelagic and roam open water until roughly 50cm, after which they shift to a bottom-dwelling life on reef.
  • Favour areas of high current; in some locations fishing is only productive around the tide change when current slackens enough to fish effectively.

Key Locations

  • Three Kings Islands (Northland) — remote offshore reefs and banks known for concentrations of large fish.
  • Ranfurly Banks (Bay of Plenty) — a major deepwater structure fished by charter boats out of the Bay of Plenty.
  • White Island area (Bay of Plenty) — reef and bank structure that once held fish in shallower water; now fished deeper.
  • Hawke's Bay — site of the current NZ record (68kg, 2005); deepwater reef structure along the east coast.
  • Coromandel offshore — deep pinnacles and drop-offs; associated with unverified reports of very large fish.

Specific Spots

  • Pinnacles and steep drop-offs in 200–400m are the primary targets — the rougher and more broken the bottom, the better.
  • Caves and undercut reef faces hold larger adults; use a sounder to mark structure before dropping, setting your drift so baits land just upcurrent of the mark.
  • Slack-tide windows are critical: fish move up off the bottom to feed when current eases, making bites more frequent and retrieves more manageable.
  • Smaller juveniles can turn up over open sand or mud away from reef — worth a drop if the sounder shows fish suspended above a flat bottom.

Hapuku FAQ

Answers from onWater's species guide.

What are the best lures and bait for Hapuku?

Fresh whole or large cut fish baits are the standard, kahawai, jack mackerel, barracouta, and blue cod all work; fresh and oily beats frozen every time at depth where scent carries the load.

When is the best time to fish for Hapuku?

Hāpuku can be targeted year-round in New Zealand; no strong seasonal closure applies to recreational fishing. Settled summer and autumn weather (December–April) makes offshore trips to deep banks more accessible and comfortable.

How do you catch Hapuku?

Almost all recreational hāpuku fishing in New Zealand is done from boats, drifting fresh baits on heavy bottom rigs over deepwater reef structure located with a sounder.

What do Hapuku eat?

Feeds on fish including tarakihi, mackerel, blue cod, gurnard, hoki, and barracouta, match this with whole fresh fish baits or large cut baits rather than small pieces.

Where do Hapuku live?

Native to New Zealand waters; found around the entire coastline from the far north to the deep south, including offshore banks and islands. Adults hold tight to reef structure, pinnacles, drop-offs, caves, and rough foul bottom, typically in 60–400m, though the range extends to 800m.
