You can fish over any tide. I find fishing for yellow eyed mullet is better at low tide or further down in the shallows at high, use pre made sabiki traces or make some up with really small hooks. Pretty much the best bait at the Pier seems to be salted bonito especially for kahawai and you’ll catch pretty much everything else on it. If you can catch mullet and crabs for bait during the day then you can go for schoolies(mullet) and rig (crab) at night. Squid’s also good if it’s all you can get.
