I generally fish 20gm silver hex ticers on a 6lb spin set at the diversion. If they follow but don’t take remove or add the red tag. Smaller lures will generally catch more fish, you can also vary the retrieve or try a back and forth sweeping action with the rod tip whilst winding in.
The rivers gonna be buggered again for a couple of days, big rain up the waihopai valley again>
Tide wise normally last 2 hours of incoming to first 2 hours of outgoing.
