Top colt and leading group one New Zealand Derby (2400m) contender Demonetization is off limits.
The $7 co-favourite with Age of Fire for the Vodafone-sponsored classic, the son of All Too Hard has been the subject of intense overseas interest.
Trainer Nigel Tiley said Demonetization's Auckland-based owner Narendra Balia had knocked back all approaches.
"There's been a lot of interest in the horse and he's turned down some pretty big offers. He told me he's been waiting 25 years to get a good one so he just wants to race him.
"He was one of my first clients when I started training back in 1992."
