Sir Slick's Thorndon Mile win at Trentham on Saturday was not enough to sell his half-brother at Karaka yesterday.
The Zabeel-Miss Opera colt, offered by Monovale Farm, was passed in at $240,000.
Sir Slick, who has now earned more than $1.6 million, is one of four winners left by Miss Opera and two others have been stakes placed.
Meanwhile, Sir Slick might return to Australia in the autumn.
His fruitless spring campaign in Melbourne has not deterred owner-trainer Graeme Nicholson from considering a tilt at the A$2 million Doncaster Mile at Randwick on April 18.
"He didn't like the tracks in Melbourne but it might be different in Sydney," Nicholson said.
"We might be able to fox him into thinking it's a pretty good place."
Nicholson is also keen to return to Hong Kong in April, though not for the same race as last year.
Sir Slick tackled the 2000m Queen Elizabeth Handicap last year but his target this year would be the Champions Mile.
In the meantime, he will follow the weight-for-age races in New Zealand, with his next assignments being the $200,000 Whakanui Stakes (2000m) at Te Rapa on February 7 and the $200,000 Otaki-Maori Weight-For-Age (1600m) at Otaki on February 20.
