Welsh club Scarlets have confirmed Brad Mooar is requesting a release to join Ian Foster's All Blacks coaching team next year.
Mooar is four months into his three-year contract as Scarlets head coach and the Herald understands the club expects "significant compensation" from New Zealand Rugby before they will agree to a release.
Scarlets are understood to be miffed about discovering Foster's approach to Mooar via the media.
Former Crusaders assistant Mooar has made a big impression since arriving and guiding the West Wales club to seven wins in his first 10 matches in charge.
