Hasahalo displayed a faultless sense of timing when she bounced back to winning form at Riccarton.
She had failed to flatter in two previous three-year-old appearances before she came from the back with an undeniable finish to claim Saturday's Gr.1 gavelhouse.com New Zealand 1000 Guineas (1600m).
Hasahalo had been among the leading fillies last season, winning the Gr.3 Eclipse Stakes (1200m) and finishing runner-up in the Karaka Million (1200m).
"I was really happy with her last run at Ellerslie in a strong Rating 85 race," trainer Stephen McKee said.
"She got back and never got a clear run and before that she struck a wet track. There was still a question mark about the mile today, but she got the job done well and found the line strongly." As is her racing pattern, Hasahalo drifted off the pace and when rider Sam Spratt found clear air at the top of the straight she lengthened stride.
