All Blacks boss Steve Hansen says his side made "some improvements" in tonight's 28-27 victory over England.
The one-point win in Dunedin was enough to see the All Blacks seal the series ahead of next weekend's third test in Hamilton, but the first quarter of the match saw more basic errors from New Zealand after last week's ragged win at Eden Park - where an under-strength England also pushed the world champions close.
Hansen pointed to a poor start and said there was still some basic work to do.
"You can only step up as high as the opposition allow you. We made some improvements, we'll, probably look at the first 20 minutes and pull some hair out, but we'll look forward to Hamilton," Hansen said.
"We were pretty calm at halftime when we were in an arm wrestle.
"Our scrum and lineout were good and we were able to put pressure on their ball as well. When the tight five does its job it is a lot easier on everyone else.
"Ben Smith's cover tackle on Manu Tuilagi was the turning point."
Likewise, All Blacks captain Richie McCaw said the opening 10 minutes was particularly poor from his side - where England could have been 15-3 up had Tuilangi scored.
"We lacked energy in the first 10 minutes and a couple of mistakes in a row put us under the pump," McCaw said.
"But we started to get into the game towards the end of the first half and we just wanted to get momentum in the second half and get points early to get in control of the game.
"The series was probably secondary to putting in a good performance. We were a bit disappointing last week but we got the result. We made a lot of mistakes and played to a level that's not of the All Blacks."
McCaw reserved praise for Dunedin's covered stadium.
"I've just got to say this stadium is outstanding. I know all the boys were looking forward to playing here and passing around a dry ball. With an atmosphere like that it was awesome."
Meanwhile England captain Chris Robshaw says "glimpses" of good play need to be expanded, but says he's pleased with the way his team are progressing.
"I'm extremely proud, the boys have come a long way in the last few weeks and we keep getting better. We just lost a bit of control in the second half early on," Robshaw said.
"We showed glimpses. We've lost the series now but have got another week and one massive game to come. We're going to come out fighting again."
