The official anti-doping agency in New Zealand is considering testing high school students, according to Radio New Zealand.
Drug Free Sport New Zealand is an "independent Crown Entity" and is responsible for "implementing and applying the the World Anti-Doping Code in New Zealand."
According to Radio New Zealand:
Concern that the use of these type of drugs has spread from adults to high school students has been raised after the agency told a parliamentary select committee on Wednesday the practice was happening overseas and should be checked out in New Zealand.
Drug Free Sport New Zealand chief executive Graeme Steel told Radio New Zealand's Checkpoint programme on Wednesday there is more pressure on younger athletes to perform and his agency has been told that increasing numbers are using supplements.
"And we know well that when you begin using supplements, unless you're very careful, you can use the wrong ones - some that are contaminated, some that contain banned substances."
Mr Steel says the agency will do further research into what other organisations are doing in terms of testing young athletes.
