Conceding a record score and margin to England, the All Blacks were well beaten and Hansen acknowledged as much.
"The right team won, they played some outstanding rugby," he told SKY Sport.
England had pressured the All Blacks and didn't allow them to play their game, a style which has dominated world rugby in 2012 with Sunday's loss the first experienced by the side this year.
Being 12 points down at half-time was nothing, he said and at 14-15 down New Zealand were back in the game.
But England got the ball back when New Zealand made an error and that gave them the confidence to kick on for the win, he said.
"Pressure does funny things to you," Hansen said of the uncharacteristic mistakes in defence the All Blacks made.
"It won't do us any harm to go into a summer a little bit grumpy," he said. "Once we pull our bottom lips up we will reflect on the year which has been pretty good. We introduced nine young players and played some good rugby. At the end of the day we have no excuses, we prepared as well as we could."
Captain Richie McCaw said the defeat was 'bitterly disappointing'.
"They [England] played particularly well. They caught us on the hop. Just after half-time we got our momentum back but they then got theirs back when we coughed up ball at a vital time.
"It is disappointing but we will bounce back for another day," he said.
England captain Chris Robshaw said his side had been written off which had fuelled their fires. They had stuck to their game plan and processes while also having a bit of luck with the bounce of the ball.
"But against the world champions you need a bit of that," he said.
England were a work in progress and they were starting to click, he said.
"It is a great way to finish the series. I couldn't believe it, it has been a heck of a day."
Player of the day flanker Tom Wood, who played for North Otago earlier in his career, said, it was a day to live long in the memory.
"To win in that style against a quality time like the world champions was brilliant," he said.
