New Zealand assistant coach Steve Hansen has no argument with the one-match bans handed out to prop Tony Woodcock and wing Sitiveni Sivivatu following Saturday's 32-19 victory against Australia in Tokyo.

Hansen accompanied the pair to the judicial hearing where judicial officer Peter Hobbs, of Wellington, found Woodcock guilty of striking George Smith with his elbow in the final minute of the contest and Sivivatu guilty of a dangerous mid-air tackle on Adam Ashley-Cooper which also earned the winger a 10-minute spell in the sinbin at the National Stadium.

The suspensions mean at least two changes will be made to the All Blacks starting line-up to take on Wales in the Millennium Stadium on Saturday.

Hansen said the players had received a fair hearing.

"We just have to accept the two penalties we got and move on," he said.

"Obviously we've got two guys we can't select so from that point of view it does (complicate things).

"But we've got a group of 33 so someone's demise is someone else's good fortune.

"We've just got to get on with it now and plan for next week."

Loosehead prop Wyatt Crockett is likely to come into the front row for just his second Test start, while Zac Guildford could be in line for a berth on the vacant left wing.

A calf injury to Daniel Carter, who looked in some discomfort on Sunday, is providing a further selection headache for the All Blacks coaches, who will be keen to have their star pivot play against a Wales side feeling confident about their chances of ending more than 56 years of hurt against the New Zealanders.

"He's sore this morning and we won't really know till we get to Cardiff and get over the flight," Hansen told www.stuff.co.nz ahead of the team's departure for Britain.

"I would imagine either way he won't be doing too much earlier in the week."
