Canterbury first five Richie Mo'unga has been called into the All Blacks squad as temporary cover for Beauden Barrett for this weekend's Test against Australia in Brisbane.
Barrett is suffering symptoms from the head knock he sustained against South Africa last weekend.
It's Mo'unga's first official inclusion in the All Blacks squad but he's unlikely to feature this weekend with Lima Sopoaga and Damian McKenzie offering cover at first five.
Meanwhile Auckland lock Patrick Tuipulotu will stay with the squad as cover for Luke Romano who remained in New Zealand following the birth of his son.
Fellow lock Brodie Retallick has also stayed at in New Zealand.
