Mettrick, who starts in his new role in January, will become head of partnerships in Henderson’s advisory and partnerships team.
Reporting to Henderson head of UK retail Simon Hillenbrand, he will be responsible for spearheading the asset manager’s relationships with third parties, including platforms and life companies.
Mettrick was most recently sales director and head of strategic alliances at Artemis. Prior this, he was at New Star Asset Management from 2003 to 2009, holding the role of sales director for strategic alliances.
Henderson bought New Star in April 2009. Several of its current sales team, including Hillenbrand, were originally at New Star.
Hillenbrand commented: “It is very important to have someone with his depth of experience and knowledge of the third party client base as we head towards RDR and beyond.
“I believe that Sam fits the bill perfectly and we are looking forward to working together again.”
