The Scarlets have announced that Brad Mooar will take over from Wayne Pivac as head coach from the 2019-20 season.

Pivac is set to succeed Warren Gatland in the Wales hotseat after the 2019 World Cup, with Mooar arriving after three years as assistant coach at double-defending Super Rugby champions the Crusaders.

Mooar has also enjoyed stints as head coach of Southland Stags and attack and backs coach with the Southern Kings in South Africa.

The Scarlets confirmed the news on Monday, announcing that Mooar has been signed "for the 2019-20 season and beyond".

"The opportunity to take on the role of head coach at the Scarlets is simply too good to pass up and is both an exciting challenge for myself, and a fantastic opportunity for my family to experience life on the other side of the world," Mooar said.

"The Scarlets is a rugby brand that's known the world over, it is a winning club with an extremely proud history, passionate fans, and is aspirational in its goals.

"It is humbling to be offered the opportunity to take the reins after the great work Wayne Pivac has led, as he moves on to the Wales job.

"In addition to Scarlets' on-field rugby pedigree, with a strong squad of talented and largely homegrown players, the club represents its wider community with great pride and dedication.

"My family and I are looking forward to being part of the wider Scarlets community integrating into life in West Wales."
