The set-piece was cohesive and accurate and there was a compelling list of interplay on attack when they got into a rhythm after halftime. Aided by a tough sinbin decision against Owen Farrell, the All Blacks were too good with the ball as they burst into that dynamic interplay few other sides can replicate.
The reservations are about the All Blacks' attitude and whether they have absolute ruthless instincts to combat their opponents and then, if they get the edge, grind them into the turf.
After the awkward start at Eden Park, they knew all the areas they had to fix and if any of them went off task the coaches and selectors would have given them plenty of reminders. Future places were at stake.
New Zealand as much as the All Blacks zeroed in on Forsyth Barr Stadium to watch the response. A disciplined accurate start was imperative.
In the fourth minute referee Jaco Peyper had them on a sinbin warning for repeat offences.
Fortunately England squandered several chances. After a charge-down, Danny Care chose the short side with his backline all out wide while a touch short of the interval, from a turnover, Manu Tuilagi was well short of pace to be a test wing when he was run down inside 60m.
When the All Blacks got a similar chance after the break, Ben Smith showed his attacking clout was as sharp as his defence to round out the turnover try. The All Blacks banged on 15 points and conceded three before Farrell went to the bin and yielded another converted try. That was the game. Then take your pick. Either the All Blacks took their sprigs off England's throat or the visitors, back to a full side, pricked more holes in the hosts' temperament. You had to admire them for their mettle.
Most sides would have buckled and bombed the last 10 minutes. England bit back with two converted tries and also had the resistance to hold All Black captain Richie McCaw up over the line.
This has been a real test series and the sort of examination which will benefit both squads ahead of the high altar examination in October 2015.
