"It will be sad not having him come back to the stable for next season because he is a beautiful horse and a real pleasure to have around the place.
"But I understand the new owners motivations. He probably has nothing left to prove down here whereas if he can go up there and get a really quick mile time it would really help his stallion career in North America."
While no trainer has been confirmed for Lazarus it is believed leading horsemen Jimmy Takter and Ron Burke are in the running to take over his career.
Lazarus's departure caps an unbelievable series of elite level horses leaving the All Stars stable's care in the last year — with Smolda, Vincent, Waikiki Beach and Heaven Rocks also now gone.
But that still leaves him with two obvious contenders for this year's New Zealand Cup and one "smokey".
"Ultimate Machete and Dream About Me are the two big ones who both have open class form at that level.
"Ultimate Machete is a logical New Zealand Cup horse, it is the ideal race for him while Dream About Me is an Auckland Cup winner and we will just have to keep her feet sound.
"And while we have a few other who could make it to the Cup, Thefixer is one who we definitely have it in mind for."
Purdon and training partner Natalie Rasmussen suffered another, far less significant, blow yesterday when they withdrew Luby Lou from the Jewels 3-year-old trot.
The NZ Derby winner has been struggling with a cut on her leg after losing a fight with a fence.
Defending champion Paramount King was also withdrawn from that division of the Jewels yesterday.
