"It's so exciting," said Murray. "I'm very rapt with her.
"In her last four or so runs, she'd had checks. She didn't jump from Box 7 last week and she was checked and became unbalanced. She didn't get touched today and that's the difference – she's probably run five to six lengths quicker.
"She started off her racing career with Punga (Brian Goldsack), but I actually bred her, and when he finished training, I got her back up here.
"The litter is four-and-a-half years old now, but it looks like Ariana Sunset could keep racing for a bit longer now."
Murray has six greyhounds at his property, including one who has retired from racing. He never bets on his dogs, but the thrill of Wednesday's win was enhanced by the fact that all races on the day were worth double their usual prizemoney.
"It's been a really good day," he said. "She's up to Class 2 now, which is hard to believe, really. It took her about 50 starts to get her first win, and now she's had three."
TAB NZ's record of New Zealand greyhound racing tote win dividends dates back to August 1998. The previous highest win dividend was Cover To Cover, who won at Invercargill back in October 2013 at a price of $78.10, while more recently Bigtime Chloe paid $76.90 when she won a heat of the 2019 Group 1 Silver Collar at Manukau Stadium.
