Have caught a few around Oriental Bay at night under the lights. Charge up a squid lure, then cast as far as you can with light spinning gear. Retrieve slow to medium. If you feel a tap tap, or some resistance then something is interested. Once you reach the drop off retrieve quickly and recharge the lure and cast again. They don't seem keen to cross the drop off into shallower water. A reasonably calm night at high tide is good.
