We used to get them off the akaroa wharf but we didnt target them.. It was just what we caught. We used a running rig with small mullet, pilchard even spottie etc as bait.I’d say any shallow harbour type place would be a good start.
Used to get alot of rays off there as well. Some of them were huge and would spend ages fighting them only to be cut off on boat moorings or the line simply snappping.
