What he wrote didn't make sense
All Black coach Steve Hansen spat the dummy over the sneaky behaviour of an English journalist, which supposedly revealed confidential team information.
Hansen said the journalist that reported on messages within their team meeting room was guilty of a "breach of trust".
A reporter for London's Daily Telegraph newspaper gained access to the room at the All Blacks' hotel and published a story outlining several of the team's motivational messages posted on the wall.
Hansen was pleased the story revealed little that would benefit England ahead of Saturday's Test at Twickenham.
"But when there's a breach of trust by you guys, it's always disappointing because we're trying to work together," Hansen told a media gathering.
"I just wished he [reporter Oliver Brown] had come and asked me what it all meant because what he wrote didn't make sense."
Hansen said All Blacks management were critical of themselves for leaving the way clear for such a breach and would review their security.
One of the written messages reportedly said: "We are the most dominant team in the history of the world."
Hansen had to explain the message, which he says wasn't intended to be arrogant.
"I read this week that England want to be No.2 in the world, and they're striving to be better than they are," he said.
"What we're striving to be is better than we are at the moment, which is No.1.
"If you don't look to improve yourself, you're going to go backwards.
"We've got massive expectations in our country from our fans and we wouldn't change that."
