Thanks Jax, hope you get some soon, Tauranga is a hotspot!
Tailingloop they have a few names down here, I think the full name is Yellowtail Kingfish, but mostly we call them kingi's, I have caught many of the bigger ones on live bait and jigs in deep water. The smaller "Rat" kings tend to spend summer in this area hanging around the chanel markers so they can be targeted on fly, but you have to hang on once hooked up or they are straight back to the mark to bust you off!
Here are a couple of pics.

A better one.

All the best.
