New Zealand forwards coach Jason Ryan has urged the All Blacks to show more consistency as they head to the final leg of the Rugby Championship competition against the Wallabies.

Ian Foster's men had a mixed year as they lost the home series against Ireland and managed a defeat and a victory apiece against both the Springboks and Argentina in the first four rounds.

The All Blacks ran in seven unanswered tries in Hamilton with Ethan de Groot, Caleb Clarke, Reiko Ioane, Jordie Barrett, Ardie Savea, Brodie Retallick and Beauden Barrett all crossing over to complete a 50-point victory.

"We shouldn't have to be responding as All Blacks," Ryan said.

"Consistency is now the challenge, and we're good enough. There was some good stuff that we should be proud of, and we are.

"The boys have been hurting but they should be confident now after that performance."

Meanwhile, veteran lock Brodie Retallick, who made a comeback from a cheekbone fracture lauded the under-fire coaching group led by Ian Foster and Joe Schmidt in the team's revival.

"I've been here 10 years and this is probably the most intense and accurate week of training I've been a part of," he said.

"I think the boys are really buying into what Fozzie (Foster), Joe and Jason are bringing -- if you get a tight five that's playing well, and physical, it allows everyone else to play.

"But it can't just be done for one week. Consistency is the key now."
