The full extent of Steve Hansen's fury will be felt behind closed doors this week as he attempts to drill into his players the need to stamp out silly penalties.
It was the casual and needless acts of stupidity that gifted Ireland nine points which had the All Black coach most alarmed.
The All Blacks have prided themselves on their discipline in recent seasons and there they were last night flopping over the ball in full view of the referee, pulling down scrums and late tackling.
"There were too many errors and there were too many silly penalties," said Hansen. "When the penalties are stupid, that's when you get frustrated.
"We will have to go back and look at how we prepared. We thought we had prepared well but we obviously hadn't because if we had, you don't give away stupid penalties in the red zone."
