The head of New Zealand's anti-doping agency says there is an increasing risk of high-school rugby players using performance-enhancing drugs, and drug testing may be implemented to combat the issue.
Drugfree Sport NZ chief executive Graeme Steel said there were concerns that the use of supplements could be the start of a bigger problem among under 19-year-old players.
"At the moment there are no specific plans to do anything other than initial research, but looking forward and given the experience overseas, we think there's a significant likelihood that we will need to do some testing at some point," Mr Steel said.
He said there was strong evidence of drug use in schoolboy rugby overseas, especially in South Africa and in the UK. "Given the international experience and given the growing pressure on the young kids at that level, we are thinking that there's a strong chance that will be where we get to, but there's a few steps to go before then.
"There is currently no move with respect to first XV, except the realisation that there's potentially a problem, certainly around supplement use and possibly around other drug use. We want to work with the schools to make sure we get ahead of the problem and don't get blindsided by it."
