The penalty was handed down by Prof Geoff Hall, of Dunedin and Phil Welch, of Blenheim, representing the Judicial Control Authority for racing.
They found in March the drug charge relating to her positive urine test to methamphetamine on May 7, 2005 to be proved.
The disqualification will begin on June 25 so she can make arrangements for horses being trained on her property.
The costs figure is a 50% estimate of costs incurred.
The costs will be divided on a proportional basis between New Zealand Thoroughbred Racing legal costs and disbursements and the JCA costs.
Cropp led the premiership with a record 197 wins in the 2004-05 season.
She was also the leading rider the next two seasons with 146 wins each time.
She has not ridden for some weeks due to a shoulder injury.
• Jay Misbah has replaced the injured Daniel Stackhouse on Eyes On The Kash in the rating 67 1600m race at Oamaru tomorrow.
Stackhouse broke his collarbone in a steeplechase fall at Riccarton on Thursday.
He will also miss the rides on Come On Jimmy (race 1), and Daatldomee (race 3) tomorrow.
Eyes On The Kash ran fourth over 1200m at Oamaru last Sunday in her first race for three and a-half months.
She won a 1400m maiden race on a slow track at Oamaru last July.
Eyes On The Kash was ridden last Sunday by Centaine Spittles, the stable apprentice for John and Karen Parsons, trainers of Eyes On The Kash.
Spittles underwent surgery on Tuesday to have a rod removed from her leg.
She is expected to be away from race-riding for up to eight weeks.
Spittles had the rod inserted after she broke the leg in a race fall at Gore in December 2007.
Mr Incredible, a rival for Eyes On The Kash, is now trained by Jan Hay at Ashburton.
Mr Incredible won a 1400m maiden race on a slow track at Hastings in June 2007 when trained by Lance Noble at Matamata.
Misbah has the mount on Royal Flight (race 10).
The 4yr-old mare trained by Brian and Shane Anderton has won two of her three starts.
She won over 1400m at Oamaru on May 12.
Five horses are without riders in a 14-horse field for apprentice riders tomorrow.
The connections will be offered the option to start with a 3kg penalty if an apprentice is not available.
• Luke Nolen has been engaged for Reggie in the Brisbane Cup and Steven Arnold for Markus Maximus in the Queensland Derby at Eagle Farm today.
They are replacements for the injured Zac Purton.
• Chris Butt, the 17-year-old junior driver, had his third win from four drives on Chief Inanga in the Nelson Winter Cup Prelude at Richmond Park yesterday.
Butt has also won with Chief Inanga at Alexandra Park and Oamaru.
He finished third the other time he has driven the 4yr-old.
Butt has driven eight winners in his first season as a reinsman.
The combination will command respect in the Nelson Winter Cup tomorrow.
Chief Inanga is trained by Tim Butt (an uncle of Chris) and Phil Anderson, who also have Centreofattention in the Cup.
Centreofattention did well for sixth yesterday after leaving stride in the early stages.
Anthony Butt, father of Chris, drove Explosive Turk and Woodlands Lifeline to win yesterday.
• Mach Banner justified his hot favouritism when he held on to win the Northern Hemisphere Yearling Sales Prelude at Alexandra Park last night.
Mach Banner is trained by Robert Dunn for Mach Banner Breeding Ltd, which bought the colt from Rolleston trainer Jamie Gameson after he won a trial at Addington on April 24.
Gameson had bought the Mach Three-Regal Banner colt for $16,000 at the 2008 premier yearling sale when he was offered by Templeton breeder Dennis Moore.
Mach Banner is the third foal of the Caprock mare Regal Banner, a winner.
