Hurricanes hooker Dane Coles is the one new face in the wider training group asked to assemble for an All Black camp in Wellington this week.
Charlie Faumuina and Cory Jane who were picked but then injured ahead of the June test series with Ireland have been recalled for the two-day camp starting on Wednesday.
Twenty eight players from the four franchises who have finished their Super 15 campaigns will attend the camp before the All Black squad for the Rugby Championship is revealed the day after the Chiefs host Saturday's final against the Sharks.
"We will mainly be looking to re-establish the way we do things in the All Blacks, and it'll also give those players who haven't played much rugby recently, the chance for a good hit-out," Hansen said.
Coles had been included in the group as part of the All Blacks' on-going search for new talent.
"We already know a lot about Keven Mealamu, Andrew Hore, Corey Flynn and Hika Elliot and now it's Dane Coles' chance to come into the All Blacks environment and gives us the opportunity to see him at closer quarters."
Mick Byrne has rejoined the All Black support staff as a specialist skills coach.
