Former Hurricanes and Blues first five-eighth Jimmy Gopperth says the British and Irish Lions need one key tactic to have a chance to beat the All Blacks - all-out attack.
Gopperth has impressed for Wasps this season, leading the London side to a 10-point lead in the Aviva Premiership where he is the current top points scorer.
Gopperth played for Wellington against the Lions in the side's last tour in 2005, a 23-6 victory to the tourists.
The former Wellington number 10 said attack is the only way the Lions will achieve a series win in New Zealand for the first time since 1971.
"I'd be going out there looking to run them off their feet," he told the BBC's Rugby Union Weekly podcast.
