Left Mokau on the high tide at eight yesterday morning with a reasonable s/west swell breaking on the bar. Got through after a big set and headed towards the mokau trench in slightly lumpy seas. Slowed at 50 meters and caught a few albies and skippies for bait and then continued on our 60 mile trip. A wind against the swell was making progress uncomfortable with whitecaps gradually becoming bigger so at a 115 meters we set some lures to troll. Water wasnt really good 19 deg and green but much more comfortable to travel in. Saw a sunfish and a large mako on the way. Once we hit the 150 meter mark 7 tuna boats came into view workin the trench and southern shelf. However the tuna seem to have shifted and 1 boat had only caught 9 tuna by 11-30 am. They all promptly headed north, destination off muriwai. Pulled in the gear at 200 meters and popped the locks on the puka cupboard. Less than 1minute after the baits hitting the bottom both rods were buckled with puka around 20kg. 3 drifts and 7 puka later the sea had flattened out so a clean up and back to trolling. Went out to 400 meters and worked the northern bank of the trench. Sadly very little sign of life this trip but good to get out and explore this awesome play ground
