Five players have been called into the All Blacks camp in Dunedin to join the squad in preparation for Saturday's second Bledisloe Cup Test against the Wallabies.

The All Blacks have confirmed Nehe Milner-Skudder, David Havili, Kane Hames, Akira Ioane and Atu Moli have all joined the team in Dunedin after Saturday's 54-34 win in Sydney.

Milner-Skudder was originally named in the All Blacks' Rugby Championship squad but was released to play for his provincial side, the Manawatu Turbos, in their Mitre 10 Cup match against Wellington yesterday.

The Hurricanes star donned the No.15 jersey in the 41-29 loss which also featured axed All Blacks winger, Julian Savea.

The other four, including loose forward Ioane, are new to the squad with no official reason yet given to the additions.

Veteran flanker Jerome Kaino returned to New Zealand prior to the game on Saturday night to deal with a "personal matter" after Australian newspaper the Daily Telegraph reported earlier that day he had cheated on his wife with a former Australian model.

Kaino was not named in the matchday 23 for the match but the NZR have yet to state his availability for the match on Saturday.

There has also been no further announcement on the state of prop Wyatt Crockett who suffered a serious head knock coming off the bench for Joe Moody.

"Crockie has obviously got a concussion worry, we will see how he goes in testing," All Blacks coach Steve Hansen said after the match.

"But it would probably be pretty fair to say we would follow the same protocol as we do when anyone gets a head knock. We won't be making him available, regardless."
