Forty years ago, we used to tow a runabout from Rotorua to the coast near Whakatane and launch at the mouth of the Rangitaiki River. The object was to fish for kahawai around the river mouth, but not using traditional techniques like trolling the Smiths jig - a plastic lure which is flat on one side and rounded on the other, with two large hooks pinned to one end of the flat side.
We had stumbled on a technique that was far more fun. When drifting around the edge where the brown river water met the green salt we used a trout spin rod to cast out a lure, let it sink, then wind it back in. The favoured lure was a silver toby, a common lure used for spin-fishing and trolling for trout. The kahawai leapt all over it, putting up an aerial display that would put trout to shame.
On one occasion, while unhooking and releasing a large kahawai in the net, another rod suddenly jumped and the reel screeched as line was torn out. After a lengthy and hard fight, the fish surfaced by the boat and surprised all on board - it was a beautiful 5kg gold and red snapper. When gutted, the stomach was found to be packed with dabs, baby flounder about 75mm long. On reflection it was not such a surprise. It took little imagination to picture the silver lure fluttering down to hit the bottom with a puff of sand and that snapper must have been right on the spot.
And so it can still be done. When terns and gulls fluttering and diving signal bait fish being driven to the surface by predators, which in our inshore waters are invariably kahawai, the same approach will work wonders. But we also have other lures that drive the kahawai crazy. Trout lures like the cobra and Tasmanian devil or the silicone smelt fly patterns with wiggly tails will all appeal to the kahawai. But they lack weight so need to be cast out with a fly rod or a spin rod with a half-ounce ball sinker above a swivel placed about half a metre up from the lure.
Such a combination can also be slow trolled, and can be rigged on any type of light snapper rod. And you never know what it may appeal to. Rat kings will love it and will test the tackle when hooked. One such approach yielded a large jack mackerel, or yellowtail.
