Beauden Barrett has been ruled out of the Blues' opening round Super Rugby Pacific match against Moana Pasifika as he continues his return from concussion.
Barrett, who this season makes his return to the Blues following his Japanese sabbatical, has struggled with concussion symptoms since sustaining a heavy blow in a front-on collision in the All Blacks loss to Ireland in Dublin last November.
In a positive sign, Barrett trained alongside the Blues' returning All Blacks in Auckland on Saturday before the team travels to Wellington on Sunday for their first preseason hit out against the Hurricanes.
After that match the Blues continue onto Queenstown where they will be based in a bubble, alongside the other five New Zealand teams, for the next month as organisers attempt to prevent games being cancelled due to the latest Covid outbreak.
While his full nine-strong All Blacks contingent are available on restricted-minutes duties for round one, Blues coach Leon MacDonald confirmed Barrett will not feature immediately as a cautious approach is adopted with his return to play.
