"We'll look at the Opunake Cup now, although he's going to end up with topweight."
Taurus, who was second in the Hawera event in 2013, could also be in line for another trip to Riccarton for a third crack at the Group 3 Winter Cup. He was runner-up three years ago and sixth in 2014.
"We'll probably have to think about it and further down the track there's the Foxbridge Plate," Rayner said.
"I won that with Baltaine a few years ago and this horse is right up there with him."
Taurus was given a cosy run behind the pace by Jonathan Riddell and they proved too strong over the final 200m for Designated Driver and Endure.
The victory, his first at 1600m, was just reward for a loyal band of owners who have supported the Rayner stable for years.
The Starry Eyed Syndicate has had some notable gallopers, including All American, arguably the Rayners' best until his untimely death, Valhalla, Doc Holiday, Wolf Pack and Just A Lover who ran third on Saturday.
The Rayners also produced Star O'Fraaj to run third.
Spokesman Graeme Berghan and several other syndicate members were on hand to witness the win. The Aucklander said syndicate members had pretty much stayed the same over the years and they had had immense fun.
Changes to barn-mate Hundyamonth's training regime and gear paved the way for the 4-year-old to post a front-running success under apprentice Holly Andrew in the Wanganui Chronicle 1340m.
"He's a thinker so we schooled him over the pony fences this morning and put the blinkers on him as well," Rayner said.
That win, too, was just reward for his large band of owners. He is raced by the St Johns Club Syndicate No1 which involves around 20 club members, including president, Royce Tunbridge.
The club was rocking on Saturday night with owners, the trainers themselves and supporters taking centre stage.
