The breakwater and area around it is the only place I know of but there could be others. Fishing with a sabiki type trace off the rocks you could expect to catch mullet, spotties, kahawai and the odd warehou and if casting out further you’ll probably get a lot of small dogfish. You can catch rig, school sharks, skate and possibly elephant fish as well. I’m sure there’s a lot of other species that could be caught there just need to put some time into fishing the area. Haven’t seen any red cod around but haven’t really tried catching them.
If targetting the rays you need a decent reel with at least a few hundred meters of 30lb + and a leader of 60lb plus to help landing it and also your line is bound to get dragged through a whole lot of weed so a long leader helps.
