On the Ocean – Hapuku a winter fishing prize

Hapuku, also known as groper, is a prized catch among Kiwi anglers due to its impressive size, delicious taste and the challenge it presents.

The deep-water fish are found around rocky outcrops and underwater pinnacles, making them a target for those seeking adventure and a rewarding meal.

Hapuku are typically found in depths between 100 and 500 metres, but occasionally as shallow as 30 metres around offshore reefs and rocky structures. Over the months of November and December, the smaller ‘pup’ ‘puka will come closer to shore. I have caught them in 12 metres of water off Ruakākā and a little deeper when softbaiting for snapper around the Hen and Chickens Islands. The good news is that bass (wreckfish) and bluenose are valuable and tasty bycatch.

Prime spots include the edges of underwater canyons, seamounts and submerged pinnacles, especially off New Zealand’s west and east coasts, including the Three Kings Islands in the north. To locate the fish, a reliable depth sounder and chartplotter are invaluable for identifying the rugged terrain and drop-offs where hapuku congregate.

Hapuku are voracious predators, feeding on a variety of fish and squid. The most effective baits include freshly caught or frozen whole fish, such as mackerel, kahawai, barracouta and skipjack tuna fillets. Large squid and octopus are also highly attractive to hapuku. When preparing your bait, aim for generous portions – hapuku are big fish and are attracted to substantial meals. Rig your baits securely to withstand both the descent and the attention of smaller fish, ensuring they remain intact until a hapuku strikes.

A tip shared with me by the late Alan Jorion was to add, via a small swivel, a 3/0 hook with a small bait. This attracts the attention of smaller reef fish such as tarakihi, which, when hooked, act as live bait.

Traditionally, ‘puka are targeted from a drifting boat. The skipper will keep anglers over the hit zone by coordinating the use of the throttle and gears. Today, many vessels have a ‘spot lock’ system as part of their electronics package that does the same thing. Many trailer boats now sport an electric motor to hold them in position against wind and/or tidal movement.

While most people will only cook the fillets, there are plenty of options to utilise the entire fish. The wings, cheeks, heads and backbones all smoke up well, as does the roe. What is left is just the guts, which make great fertiliser for the vege garden.

Always check local fishing regulations for size and bag limits, and fish responsibly to help sustain this treasured resource for future generations. Happy fishing and bon appétit!
