He took 0.68sec off the previous record set by Cog Hill in the inaugural Coupland's Mile.
Mufhasa raced outside the pacemaker, Tipulater, went clear at the 300m and won by a length and a-quarter from Vosne Romanee, who came from the rear of the field.
Sterling Prince ran on solidly for third.
Stephen McKee, the Ardmore trainer of Mufhasa, said his preference was to freshen Mufhasa for the $1 million Telegraph Handicap (1200m) at Trentham in January.
"He is unbeaten fresh up over 1200m," McKee said.
"Then again, I may have to give him a race beforehand if I feel he needs it."
Mufhasa, raced by David Archer, his partner, Diane Wright, and Archer's children, Natalie and Simon Archer, all of Auckland, has won nine of his 18 starts.
The $178,000 yesterday lifted his earnings to $382,437.
Archer bought Mufhasa for $50,000 at the national yearling sale after winning six races with a half-sister, Belle Joie, from the McKee stable.
McKee was due to travel to Melbourne at 5am today to supervise Boundless in her final preparation for the Sandown Classic on Saturday.
Greg Childs has retained the mount on the mare.
Flight Point bled during the race yesterday and he will be required to stand down from racing for three months.
Ray Coupland, the race sponsor, as principal of Coupland's Bakeries, won races with Coup Align and Coup Anabaa yesterday.
He races both horses with his partner, Jill Walls.
Trainer Michael Pitman said he would nominate Coup Align for the Telegraph Handicap at Trentham in January after the 3yr-old trounced the opposition in a rating 90 1000m race.
Coup Align, who won a maiden 1000m impressively at Wingatui on October 17 at his other start this season, led and won by two and three-quarter lengths in 55.66.
His time into an easterly head wind compared with the track record of 54.2 set by Ticklish in 2006.
"He is a high-class galloper," Pitman said.
Coup Anabaa, a 3yr-old, was having his first start.
Coup Align was bought at the national yearling on the advice of international bloodstock agent Badger Pritchard-Gordon, of England. Coupland bred Coup Anabaa after buying the mare, Nimble Feet (by Zoffany) in foal to Anabaa at the Sydney Easter sale.
He was advised in that purchase by Gordon Cunningham, of the Curraghmore stud.
Walls is also in the ownership of Coup Callum, who has just resumed work with Pitman.
He was spelled to recover from a tendon injury.
Megapins was within 0.46sec of the track record when she won the open 2000m in 1.59.79.
She won by six lengths.
Trainer John Parsons said he had no plans for Megapins, who is capable of a major middle-distance win.
David Jones, the Rakaia owner-trainer, had his major win when Madam Stravinsky won the $80,000 Canterbury Breeders' Stakes.
"It was a surprise but she has a good finish when held up until late," Jones said.
Madam Stravinsky, previously the winner of three races, had not been successful since a fillies' and mares' 1400m race at Cromwell on March 2.
The 7yr-old Stravinsky mare, a half-sister to Zastov (placed in the Doncaster and Epsom Handicaps), is destined for the Paratai Stud at Rakaia, operated by David and his wife, Pat.
They bred Master O'Reilly, winner of the 2007 Caulfield Cup.
San Bernardino achieved a rare feat by wining the Stewards' Handicap as a 3yr-old.
Graeme Rogerson, his trainer in partnership with Roydon Bergerson and Scott Lucock, won the race in 2001 with Life Of Riley.
San Bernardino is raced by Rogerson in partnership with Trevor Clarke, of Hamilton, Karl Summers and Bernard Hickey, both of Napier, and Bryce Parker, of Auckland.
Winner of the Welcome Stakes at Riccarton 12 months ago, San Bernardino is the first horse raced by Parker.
• Ronald Stam was suspended six days for careless riding at Riccarton yesterday.
Stam, riding Lord Nelson (race 10), admitted shifting near the 1100m, causing a check to Bring It On. His suspension is from today until December 10 inclusive.
• Ned Thistoll, the successful Riccarton trainer, died yesterday aged 83. He had been in ill health.
