Gatland said in a statement he was looking forward to returning home, having coached the Waikato provincial side to a championship back in 2005.
“I am really excited about the opportunity to come back home," he said.
"The opportunity to come back as head coach of the Chiefs is something that I am really looking forward to.
"The Chiefs are well known for the success they’ve had both on and off the field and the really loyal support they have from everyone within the Chiefs region."
"I am excited to come back and be a part of the Chiefs community with the players, the fans, the sponsors, it’s something I really look forward to.”
Gatland has been coach of Wales since 2008 and led his team to a Six Nations Grand Slam this season, amid a long winning run.
