Retired triathlete Kris Gemmell has been banned from participating in sport for 15 months after violating anti-doping rules.
Gemmell, who retired in 2012, was cited by Drug Free Sport NZ (DFSNZ) earlier in the year for failing to comply with the athlete whereabouts programme.
The case was initially dismissed by the New Zealand Sports Tribunal in February but DFSNZ successfully appealed that decision to the Court of Arbitration for Sport (CAS).
The international body today backed the steps DFSNZ took in relation to Gemmell's rule violation, releasing a judgement in which it banned the former triathlete from sport for 15 months.
DFSNZ chief executive Graeme Steel said the CAS decision was important because it clarified the rules around the whereabouts programme.
"The Court notes that the whereabouts programme is a 'powerful and effective means of deterring and detecting doping in sport'," Steel said. "The ruling confirms that the surprise nature of drug testing that the whereabouts programme allows is important and that Drug Free Sport NZ is right not to give athletes advance notice of testing by telephoning them."
