The former New Zealand Police constable has been head coach of the Scarlets since 2014, masterminding last year's Guinness PRO12 title and passage into the semi-finals of the Champions Cup in the same season.
Wayne Pivac will take over as Wales coach when Warren Gatland steps down after next year's Rugby World Cup, the Welsh Rugby Union has announced.
Pivac has performed the same role at the Scarlets since 2014, masterminding a Guinness Pro12 title past year and securing passage into the semi-finals of the Champions Cup in the same season.
Welsh Rugby Union chairman Gareth Davies praised the work Pivac has done at Scarlets and believes the 55-year-old has everything that it takes to bring glory to Wales.
"Both Wayne and Warren and their coaching teams, our worldwide players, supporters and everyone at the Scarlets now have clarity and there is no underestimating the positive benefit to be gained from having the time to plan properly for the future".

"It's both a huge honour and a privilege to have been asked to be the next Wales coach".
"Wayne will bring the holistic approach to the job we are looking for and will be immediately ready to pick up where Warren leaves off - he offers the complete package and we are delighted to have secured his services".
If he is appointed, it will be a return to worldwide coaching for Pivac, who was Fiji boss for three years from 2004-2007.
Gatland is a two-time British and Irish Lions head coach, winning one series in Australia and tying with the All Blacks previous year. The New Zealander has won three Six Nations championships, including two Grand Slams since taking over in late 2007.
