New Zealand star Xtravagant's first Australian start for the season has been delayed and he will not run at Moonee Valley.

Te Akau Racing said the four-year-old left some feed on Sunday morning and had a slight temperature.

He was treated and back to normal by Monday but connections decided he would miss Saturday's Listed Chandler Mcleod Stakes (1200m) and wait a week for the Group Two Bobbie Lewis at Flemington.

Affectionately known by the stable as Blake, Xtravagant has not raced since he won the Group Three Breeders' Stakes at Te Rapa on April 30 after his disappointing eighth as favourite in the Australian Guineas.

"... we do not think it is in Blake's best interests for us to gallop him tomorrow morning. Be assured that this is a disappointment not a serious problem just a frustration and an untimely one!" Te Akau said.

"He will remain on target. Instead of having three weeks until his next race after his fresh-up run he will have a fortnight which should not have any significant impact at all."

Xtravagant is a $26 chance in early markets for the Cox Plate with Winx the $2.50 favourite to defend her title.
