Some members of the squad completed the so-called Awesome Foursome - a 134-metre bungee-jump, white-water rafting, jetboating and a helicopter ride - in Queenstown.
"What they do when they are training is far more dangerous than what they did there," said Johnson.
"On these trips you need a balance. We came to Queenstown for a reason. The main reason is to prepare for the Georgia game but they have the opportunity to do things.
"In Auckland they went on the America's Cup boats. They haven't been skiing because that is too risky for injury.
"Bungee jumping is deemed to be something they can do. If any guy had an injury that would be jeopardised by doing it they wouldn't do it."
