The New Zealand Rugby Union is to establish a dedicated integrity unit to combat corruption and doping in the sport.
The union's general manager of professional rugby, Neil Sorenson says unit should be established within six months.
A government report last year found little high-level corruption in sport in the country.
However, but Lavinia Gould, a former member of the national women's sevens squad, was suspended for two years last November after testing positive for a banned stimulant.
Gould was the first player contracted to the NZRU to receive a doping ban.
Sorenson says they are also investigating reports of Super rugby players mixing sleeping pills and energy drinks to get a high.
The problem surfaced during the New Zealand Rugby League team's world cup campaign last year and the NZRL is carrying out an investigation into the matter.
