Wiggins joins from Threadneedle where he was head of UK institutional client relationships.
Prior that he was director of client relations at AllianceBernstein and also spent eight years as a principal at Mercer.
In the newly created role, Wiggins will assume leadership of the UK institutional business development team and will also be a member of the AllianzGI European business development team.
He joins just a week after AllianzGI announced an adaptation of its fund range, which included the closure of three UK-focused equity funds.
Tobias Pross, Head of Institutional Business Europe, comments: "We are very pleased to welcome Wiggins to AllianzGI as we continue to strengthen our European distribution team. We look forward to drawing on his proven expertise and experience as we work together to grow our footprint in the UK institutional market.”
