Four New Zealand players have been suspended by the country's rugby authorities for doping offences.
Zoe Berry, who played one Test for the Black Ferns against England in 2012, and Glen Robertson, a former Junior World Championship winner and ex-member of the New Zealand sevens squad, were given four-year bans.
They are joined by two other club-level players in receiving suspensions, with Rhys Pedersen and Ben Qauqau-Dodds getting 21-month and two-year bans respectively.
Berry, Robertson and Pedersen were suspended for possessing and, in some cases, using or attempting to use the stimulant clenbuterol, while Qauqau-Dodds was charged with possession and use, or attempted use, of the anabolic steroid metandienone.
“What this investigation has revealed is that there is a lot of ignorance in our community game on the issue of performance-enhancing drugs,” New Zealand Rugby general manager Neil Sorensen said.
“What has happened to these four rugby players serves as a reminder that all athletes have to be very careful about what they put into their bodies.”
