The British and Irish Lions routinely sweep their facilities at the team’s hotels for listening devices to prevent team secrets getting out before the Test series againstthe All Blacks.
A security company that worked with the team on their 2009 tour of South Africa and 2013 tour in Australia carry out the checks, Lions CE John Feehan said.
"They are experts in electronic surveillance to ensure we are not being looked at or listened to," Feehan said.
"The team room, for example, is swept regularly and if there is any suspicion they will do another sweep."
The Lions face the All Blacks at Eden Park in Auckland on Saturday in the first of three Tests.
The All Blacks were targeted in 2013 when a reporter got into the team's hotel room and revealed some of the planning written on a whiteboard.
