Rugby World Cup winning coach Graham Henry will look to impart some of his vast experience on the New Zealand Warriors after agreeing to switch codes to the NRL side.
Henry guided the All Blacks to World Cup glory in 2011 and also took charge of the British and Irish Lions in 2001 after a spell with Wales.
The 69-year-old spent seven years in charge of the Kiwis before a brief spell as assistant coach of Argentina, and over the next month will look to test his skills in rugby league.
After nine games of the NRL season, the Warriors find themselves in the bottom half of the table with eight points and have turned to Henry to support head coach Andrew McFadden.
"I've had an association with Cappy [McFadden] on a social level for quite a while now," Henry told the club's official website.
"I've got a lot of time for him as a coach and I also really enjoy his company.
"We've had some healthy discussions about coaching previously and I'm thrilled to have the chance to be able to work with him, to observe the organisation and to provide some feedback."
For McFadden, he is relishing the chance to tap into Henry's knowledge as he tries to propel the Warriors up the table.
He said: "I've always been open to the idea of having extra support to help me to develop and improve.
"In the end we are really fortunate to be able to secure Graham's services. It's a real privilege to have him involved and I know it's going to be hugely beneficial not only for me personally but the squad as a whole."
