Graham Henry will ply his coaching expertise in New Zealand rather than assist other Rugby Championship nations.
Henry will be confirmed within seven-10 days as the Blues technical advisor to Sir John Kirwan.
He had been assisting the likes of Argentina as they enter the new four nations tournament.
All Blacks head coach Steve Hansen says New Zealand rugby is privileged to have him remain in their ranks. Henry has a coaching record of about 83 percent so he's far better off giving his knowledge to another country.
Radio Sport/Newstalk ZB understands Henry won't be a full time assistant coach but will occupy a similar role to what he had with the Blues in 2003, the last time the franchise won the title.
Former All Blacks and Auckland coach John Hart says the decision to bring Sir Graham on board is a wise one.
Henry coached Kirwan in the latter stages of the great wing's playing career with Auckland.
Henry was also on the appointment committee that handed Kirwan the Blues job from a three-way tussle with Lam and Kieran Crowley.
