Confirmed: Lions coach joins Munster
Ferreira will link up with former Springboks assistant coach Johann van Graan at Munster. Van Graan is the head coach at the Irish Province.
Ferreira will become Munster's defence coach.
"JP has been part of the Lions Rugby revival and I would like to thank him for his hard work and passion," said Rudolf Straeuli, CEO of the Lions Rugby Company (Pty) Ltd.
Ferreira said he is looking forward to the challenges that await in Ireland.
"It is really hard to say goodbye to this amazing Lions family," said Ferreira.
"I have been fortunate and blessed to have been with the Lions for ten years and have been part of ten Currie Cup and Super Rugby Competitions. There have been extreme highs and lows in these ten years of service, but nothing that I would ever regret. It has been an amazing time.
"I feel that it is now time for me to improve, grow and experience a new culture, team, environment and competitions. I want to thank every single coach, player and support staff that invested in my life at the Lions Rugby Company in these ten years. I cannot thank you enough.
"I'm really excited and am looking forward to this next challenge and chapter in my and my family's lives."
Ferreira will further his career at Munster January 1, 2018.
Commenting on the appointment, Van Graan said: "We are delighted that JP is joining our coaching team. He is a great coach that has been very successful at Super Rugby level, getting his side to finals with an excellent defence record. He also has test match experience from his time working with the Springboks during the November internationals last year so brings a great amount of knowledge and experience with him. "
