Use squid all the time up here and intend to use it off the beach as first choice.Snapper love it particularly before spawning,there's something in it they need to spawn.
Try this one,two hook rig,either 5/0gamma circle or 7/0 gamma octopus.
Cut the tail off a pillie and gently insert it up into the squid.Sew the bottom hook through the squid going under and over the back done of the pillie.When you reach the head just go through one side of the squid and through the back of the head of the pillie in the boney bit.tighten each stitch singularly and gently.Now rap a couple of turns around the second hook and insert through the squid far enough from the mantel so you can get a couple of half hitches around the squid and shank of the hook.The bait will end up like a cylinder and not cast that well but on a Kontiki it would be deadly.
