I like smoked kahawai too, in fact any fish smoked seems to be alright.
You are right, Kahawai is an under rated table fish, and I’m not too sure why. Maybe it’s because they are common and easy to catch compared to trout for example. Over the Christmas break I took my kids to the Ashburton river mouth for a walk. I passed a fellow who was on his way back to his hut and I asked him if he had any luck. His reply was no trout, but a few people were catching kahawai. But not for him – “not worth catching” were his exact words!
A bit deluded if you ask me!
