A full brother to Australian champion So You Think has arrived at New Zealand's Windsor Park Stud.

The star of the Spring Carnival's mother Triassic gave birth to the High Chaparral colt late on Tuesday night.

The mare's part-owner and marketing manager of Windsor Park, Michael Moran, said the colt was very much like his famous brother.

"He's very similar to So You Think," Moran said.

"He's a lovely dark brown colour like So You Think and he has a white spot with a fine white stripe down the middle of his nose.

So You Think cost $110,000 as a yearling and has raced in Australia 12 times for eight wins including two Cox Plates and prize money of more than $5.6 million.

Such is his value as a sire, Irish racing and breeding giant Coolmore recently paid a reported $30 million for a half share in So You Think. The four-year-old has left Bart Cummings' stable and will travel to Ireland at the end of the month where he will be prepared by Coolmore's trainer Aidan O'Brien.
