Wagner signs until the end of July
Head coach Anthony McGrath said: “We have been working hard on bringing Neil back for a while. His performances were excellent last season and he offers something to the squad with both bat and ball.
“Off the field he was very much a popular member of the squad and he brings International experience to our exciting group of young bowlers.
“He showed great commitment to the club last year and was integral to what we achieved. From the minute he joined he understood exactly what Essex is all about, and we are looking forward to welcoming him back this year.”
Wagner himself said: “Once I knew there was an opportunity to come back to Essex, I was very keen to get back to Chelmsford and build on the hard work and success of last season.
“Everyone at the club made me feel welcome last year from the members to the commercial team, and I absolutely loved my time there. The squad and coaching staff were brilliant with me and I am looking forward to catching up with the friends I made and bringing more success to such a special club.”
