The Crusaders assistant coach Brad Mooar is taking over from fellow New Zealander Wayne Pivac at Welsh club Scarlets, who's replacing Gatland as Wales coach.
Mooar has been at the Super Rugby champions for three years and helped the Crusaders to a second straight Super Rugby title in 2018 alongside head coach Scott Robertson.
He was previously head coach of the Southland Stags as well as backs coach with South African sides Eastern Province Kings and Southern Kings in the Super 15.
The 44‑year‑old Mooar will join Scarlets in 2019, with Pivac taking over from Gatland as Wales coach at the end of next year's World Cup in Japan.
Pivac coached the Fiji 7s team to victory in the 2005 Sevens Rugby World Cup and was also head coach of the Flying Fijians.
Pivac has been in charge at Scarlets since 2014 and helped the region win the Pro12 title in May 2017.
