Brent Impey has announced his resignation from his role as chairman of Sanzaar, effective 31 December this year.
Brent has held the role for the last five years but has decided the time is right for a change.
"In my view it is time for Sanzaar to make some fundamental changes which are best placed to happen under an independent chair. While there was no imperative for change it was appropriate to rotate the role, however I now believe that the role of chair of a national union as well as chair of Sanzaar is a conflict for any country.
"I also hold the view that Sanzaar should become membership based. The four country consensus model is outdated if we are looking to grow the game commercially and internationally.
