there's a nice fishing area to the right of Little Oneroa as you look out to sea. A rocky shelf which drops into about 4m. I think it's called Fisherman's Rock or something similar. A staircase goes down to it from the end of the road, or you can walk all the way from Little Oneroa at water line.
I've caught reasonable snapper, and seen a great john dory caught there. I landed an under-sized kingie on a live mackerel after seeing a couple cruising the weedline.Just tossed the jack mack in un-weighted and bingo. Unfortunately it wasn't the big one I'd seen. Murphy's Law.
I reckon it'd be a decent spot for top water at the right time.
Lots of boat and foot traffic this time of the year, though. And it'll be onshore from Sunday.
The shoreline around from the Matiatia ferry looks good as well. I've done the walk minus fishing gear, and thought it'd be ideal for casting a few spinners.
