All Blacks coach Dave Rennie picking up the pieces after historic loss to Wales

New Zealand had the possession and territory to get back into the match, but Wales repeatedly kept them out.

Rennie pointed to poor starts in both halves and the speed of Wales' ball at the breakdown. New Zealand struggled to slow it down, allowing Wales to find space out wide and finish clinically.

At the other end, Rennie felt the All Blacks became one-dimensional in the closing stages. At times they moved the ball away from an area where they had numbers. At others they kept carrying into traffic after drawing the Welsh defence in.

"That's decision-making under pressure, and they provided a lot of pressure tonight," Rennie told allblacks.com.

The coach also pointed to the cost of first-half turnovers, saying he counted nine, four of them from offloads.

Rennie sees the offload as a point of difference for the All Blacks and wants his players to be sharper about when to use it and which pass to throw. He added that he had no regrets about the side he picked for Cardiff and believed the players on the field created enough chances to win. He mentioned the review would cover the coaches' decisions as well, including the team's preparation, selection and the timing of substitutions.

The All Blacks remain top of the Southern Hemisphere table, one point clear of South Africa, and can secure a place in the Grand Final with a bonus-point win over England. Rennie said he expected more from his side against England next week.

"Wales were passionate and every time they kept us out, I reckon they grew and became harder to break down," he said.

"We expect a lot more of ourselves and need to see a response at Twickenham next week."

Captain Beauden Barrett said the All Blacks were held up three times and felt a try from any of those chances could have changed the game.

"It's a tough one to take, particularly when we were building a lot of pressure and we just couldn't convert that into points," said Barrett.

"Numerous times we were held up, and just felt like we needed one of those to get right back in the game and level the scoreboard and the whole game would have changed."

Barrett added that the longer Wales held out, the more the Cardiff crowd came into the game.

"That's why it's one of the best places to play rugby when you get that support behind you," he continued.

"Feels like you're playing with 16 or 17."
