Warren Gatland has challenged referees to stop New Zealand's off-the-ball "blocking" in the British and Irish Lions Test series.
Coach Gatland revealed the Lions have already raised the issue with officials ahead of the first Test against the All Blacks at Auckland's Eden Park on Saturday.
Gatland will meet first Test referee Jaco Peyper on Friday to discuss the Lions' concerns further, in a bid for a clean opening clash.
"The frustrating thing for us is the amount of blocking that's going on," Gatland said.
