Although the All Blacks won the series with their win over Wales in the second Test in Wellington, they still have plenty to work on.
That was the word from head coach Steve Hansen, who felt their effort in the 36-22 victory in Wellington was an improvement on several fronts but there was still plenty to work on.
Hansen said the All Blacks management had to be 'reasonably happy' with the attack play afyer they scored five tries and they also defended well for long periods.
"Even when the Welsh scored their last try we were dominating with our defence, made one small mistake and they were good enough to penalise us by making a break," he said.
"There were big improvements across the board, our lineout was a lot better, we managed to put pressure on their ball and our scrum, in the end, we scored two great set-piece tries off it."
So far as the defence went he felt there was more cohesion and intensity in the hits but there weren't many rewards for getting over the ball, he said, but they would look at that. There had been a lot more dominating tackles than in the first Test.
Hansen believes his side showed greater cohesion and intensity in their tackling – compared to their effort in that facet of play in the first Test in Auckland – but there wasn't much reward for getting over the ball.
"Last week we spent most of the time scrambling but this week we came forward and put pressure on them," he added.
Captain Kieran Read said it was always important just after half-time and the All Blacks had settled into that period a little better and it was always pleasing to score off a scrum so it had been especially pleasing to do it twice on the night.
All Blacks captain Kieran Read, who was superb in Wellington, was happy to to secure the series win but wasn't completely satisfied with the world champions' showing.
"We certainly expected a really tough test match tonight," Read told Sky Sports.
"The Welsh are a battle-hardened team and came out firing at us. We really had to dig deep. We got a bit of extra ball in that second half and were able to make it pay.
"It's a team effort.
"You've got to wear a team down on some occasions and it might take 75 minutes another week.
"Fortunately we got a few tries at the start of that second half to put us ahead. We're tracking well. Obviously you want to start as well as you can but it doesn't always happen."
