The former international union coach will provide support for the club’s NRL squad and football department.
“I’ve had an association with Cappy (head coach Andrew McFadden) on a social level for quite a while now,” Henry explained, speaking to the Warriors’ 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.”
“I’ve always been open to the idea of having extra support to help me to develop and improve,” said McFadden.
“Jim [Doyle – Warriors managing director) and I have considered a number of options but it was important to take time to find the person who best fitted the position and was available to help.
“In the end we were really fortunate to be able to secure Sir 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 for the squad as a whole.”
