"It was a 10 out of 10 ride," trainer Raymond Connors said.
"I told him [Fannin] to ride him handy but I wasn't expecting that, to be honest.
"This race suits him, it's tailor-made, as he is a true stayer."
Fannin was happy to take control of the race after following his instructions from Connors.
"I was just happy to have him up there, as there looked no speed in the race on paper," Fannin said.
"He was happy in his action out in front, jumping nicely, and he is a very dour stayer, so it was catch me if you can.
"He was really relaxed and I didn't think I was going too hard. I gave him a squeeze coming down the hill and he quickened nicely.
"I know how tough he is as he had already won it two years ago so I wasn't going to sit around at that stage and he proved too tough at the finish.
"I'm two from two on the horse now so I have a big thank you to say to Mark."
Fannin went close to scoring a coveted double on the day after being narrowly beaten on Laekeeper in the other feature jumping event, the Boutique Body Corporates Great Northern Hurdle (4190m).
With the victory Wise Men Say took his career record to nine wins for 34 starts and over $332,000 in stakes earnings for owners Raymond and Mark Connors.
Meanwhile, the never say die attitude of accomplished hurdler Bad Boy Brown was on display for all to see after he produced a stirring home straight rally to claim the day's first prestige jumping event, the Boutique Body Corporates Great Northern Hurdle (4190m).
Narrowly beaten in a tight finish to the Grand National Hurdles (4200m) at Riccarton last month, the Harvey Wilson-trained 8-year-old put that disappointment aside as he rallied bravely in the final 100m of the Ellerslie feature after being clearly headed by Laekeeper earlier in the run home.
