Adore Me led in the hands of trainer Mark Purdon and drew clear to win by three and a-quarter lengths, the last 800m in 56.6.
Her overall time bettered the track record of 2.02.4 set by Jumpforjoy in the Sires' Stakes heat two years ago.
The time for Adore Me was within 0.4sec of the New Zealand record for a 3yr-old filly set by Lancome at Alexandra Park in 2010.
The win of Adore Me made the trip to Dunedin worthwhile for her Auckland part-owners, Paul and Mary Kenny. They race Adore Me with Mary's father, Auckland breeder Charlie Roberts.
"It is just terrific for Charlie, who is 88," Mr Kenny said.
A lawyer, Mr Kenny is set to be elected president of the Auckland Racing Club at the annual meeting of the club on October 30. He has been on the committee for nine years.
He was 14 years on the committee of the Counties Racing Club and had some 20 years in a judicial capacity with racing including the board of the Judicial Control Authority.
He has also raced thoroughbreds including Starina (three wins and third in the 2001 Sydney Cup) and Let's Race (four wins).
Mr Roberts bought Scuse Me, the dam of Adore Me, in the United States after she had been sold there out of the Purdon stable. The winner of eight races in New Zealand including the Taylor Mile in the then record time of 1.53.5, she did not race in the US after bleeding.
Adore Me, who won her other start at Addington on October 12, will now have an easy time before heading to Auckland for the Sires' Stakes Final.
Montecrengle, who was claimed for $15,000 two and a-half months ago, won the $15,000 Tuapeka Cup yesterday at his third start in new ownership.
Montecrengle was claimed by Nigel Armstrong, of Christchurch, on the advice of trainer Robert Dunn. Armstrong then syndicated Montecrengle, who now has 17 owners.
Montecrengle was transferred from Paul Ellis to Dunn.
Montecrengle had won two races when trained initially by Lauren Pearson at Winton. The Christian Cullen gelding won three for Ellis.
"I am in it for fun and getting new people involved in harness racing," Armstrong, a paint shop proprietor, said.
He was also involved in the syndication of Ten Diamonds and raced Franco Czar (three wins) from the Dunn stable.
Dunn took a shine to Montecrengle when he took him to Invercargill for Ellis in January and the gelding won a race in fast time.
Tim Williams had his first win as open horseman when he drove Brilliant Cruiser yesterday. Williams was out of action for three months from July after he broke his wrist playing rugby.
He subsequently shifted to Invercargill to take a position with the stable of Wayne Adams, the trainer of Brilliant Cruiser.
The 4yr-old led over the final 1300m at his seventh start.
Brilliant Cruiser is by Falcon Seelster and the first foal of Cassie's Medley, a half-sister by Badlands Hanover to Holmes Dream, the dam of Badlands Jewel (2008 Sires' Stakes Final) and Bold Cruiser (seven wins in New Zealand).
Brilliant Cruiser is raced by Brian Fraser, of Oamaru, who raced Badlands Jewel and Bold Cruiser from the Adams stable.
