Ready to take on the challenge of landing a big kingfish? These sleek, powerful predators are a diver's dream — and they’re plentiful in New Zealand’s waters. Whether you’re a seasoned spearfisher or just starting out, here’s your ultimate guide to hunting kingfish.

Where To Find Them?

Kingfish love the warm season, making their appearance from October to April. They’re common around the North Island and even venture further south during the warmer months.


Their hangouts? Look for underwater pinnacles, rocky reefs, and spots with strong currents teeming with baitfish. These areas are their hunting grounds, so that’s where you’ll find them cruising in schools, often following the same coastal paths.

How to Hunt 'Em

Hunting kingfish is a thrill like no other. These curious creatures often come to check you out, making them a bit easier to approach than some other fish. But don’t get complacent — strategy is still key.


Plan Your Approach:


  • Instead of swimming straight at them, come in from the side.
  • Use your peripheral vision to track their movements without startling them.
  • Time your dive to intersect their path for the perfect shot.

Getting the Shot Right:

Kingfish flesh is soft, so placement is everything. Aim for just above the pectoral fin and behind the gill plate. This ensures a clean kill and reduces the risk of the fish tearing off the spear.


Stay Safe While Fighting:


These fish are fighters, and an injured kingfish can thrash dangerously. Keep your line away from your body and fins, and let the fish circle to tire it out. Once it’s calm, have a buddy assist with a follow-up shot to secure the catch.


Pro Tip: Wrap your legs around the fish and grab it by the gills before delivering a quick "iki" to finish the job.

Gear You’ll Want

To land kingfish like a pro, gear up with the right tools:


Spearguns:

  • The Rebel Roller Speargun strikes the perfect balance for hunting around reefs. Its compact size gives you excellent manoeuvrability, while the roller system delivers serious power for those larger kingfish.
  • For open water and bigger fish, the Ghost Speargun is a fantastic choice. Its longer length and precision make it ideal for nailing that perfect shot from a distance.

Bags:

  • Keep your catch fresh with the Pozi Insulated Dry Backpack. Its 60L capacity is more than enough for a kingfish or two, and the insulated lining ensures your fish stays cold and ready for the table—even if your dive spot is miles from home.

Flashers:

  • These shiny attractants are your best mate for bringing kingfish within range. Drop flashers or inline flashers work wonders.

Final Thoughts

Hunting kingfish is an adrenaline-packed adventure, but remember — safety comes first. Dive within your limits, and if a shot doesn’t feel right, hold off. Respect the ocean, your prey, and yourself.
