"He's improved again on what he showed at Hastings," Nicholson said.
"He's very, very well going into Saturday. I couldn't be any happier with him. He likes the track — he's unbeaten at the course and he won the race last year, so we're going back to where he's gone well before and hopefully he can do it again for us."
Safely through the Egmont Cup, Nymph Monte is likely to tackle the Listed Ricoh Feilding Gold Cup (2200m) at Awapuni on November 2 before heading to Riccarton, where he won the Listed Spring Classic (2000m) and Metropolitan Trophy (2500m) then finished fifth in the New Zealand Cup back in 2016.
"He's grown up a little bit since then, especially mentally as he's got older," Nicholson said.
"He's always had joint issues that we've had to deal with right the way through, even as far back as when he was three. They aren't there at the moment so he couldn't be in any better order."
TAB bookmakers opened Nymph Monte as a $3.80 favourite for the Egmont Cup ahead of last year's Gr.1 New Zealand Derby (2400m) runner-up In A Twinkling, who was fourth in the same leadup race at Hastings, at $5.50, with Hi I'm Nikkita a $6 third favourite.
Leah Hemi takes the ride from barrier three, a draw Nicholson wants to take advantage of.
"We'll try and put him in the race one off the fence and hopefully he can do the job again. On form, he'll be hard to beat."
