Rafi Firdhaus has been suspended for five weeks after mistaking the laps in race four at Hokitika (NZ) on Wednesday.
Firdhaus, a 3kg-claimer, pulled his mount up after the winning post when leading on the first occasion before realising that there was still a round to go in the 2180m contest.
New Zealand stewards charged the Singapore-born jockey with incompetent riding and suspended him from the conclusion of racing on January 14 up to and including February 18.
Australian jockey Rhys McLeod was banned for two months back in 2002 for committing the exact same offence in a 3000m race at Moonee Valley.
McLeod's mount Mystic Outlaw knocked up to be beaten 72.2L, while Firdhaus' Locally Sauced fought on grimly to finish fourth, some 32.5L from the winner in swamp-like conditions.
Firdhaus bounced back with a win in race six on the card but was subsequently fined $150 for shaking hands with fellow jockey Wesley Papier when pulling up his mount, Thewayweroll.
