If you're serious about landing a trophy fish in New Zealand waters, few species compare to hapuka—known as groper in the South Island. These powerful deepwater predators were once common in shallow coastal zones, but increasing pressure has pushed them into deeper territory.
Today, most hapuka are found in 60m to 400m+ depths, holding tight to reefs, drop-offs, caves, and structure-rich seabeds.
Hapuka are:
This combination of size, strength, and habitat makes them one of NZ’s most rewarding species to target.
Fishing deep means using the right gear—there’s no shortcut here.
💡 NZDiver Tip:
Always tie your sinker using lighter mono—if you snag the bottom, you’ll lose the weight but save your rig.
Adding lumo beads or lumo sticks near your hooks can dramatically improve visibility in deep, dark water.
At depth, fish rely more on scent than sight—so fresh bait is king.
Fresh, oily baits consistently outperform frozen options. The stronger the scent trail, the better your chances of pulling fish in from a distance.
Boat handling is just as important as your gear.
🎯 Hot Tip:
Many bites happen the moment your bait hits the bottom—be ready.
If you don’t get action after a couple of drifts, move on and try another spot.
For serious deepwater anglers, electric reels are a game changer.
They don’t take the fun away—they let you fish longer and more effectively.
Jigging is highly effective when done right.
Hapuka isn’t just a great catch—it’s one of the finest eating fish in New Zealand.

However, because they are:

👉 Take only what you need and respect the fishery for future generations.
Targeting hapuka is one of the most rewarding forms of fishing in New Zealand—but success comes down to preparation, technique, and persistence.
With the right gear, fresh bait, and solid boat handling, you’ll dramatically increase your chances of hooking into one of these deepwater giants.
Gear up, go deep, and get ready—because when a big puka loads up, you’ll know about it.
