Stand-in interim head coach Clayton McMillan has signed on as an assistant coach with the Chiefs for 2022 and 2023.
In February 2020, McMillan was appointed to lead their Super Rugby campaign, while Warren Gatland takes the reins for the British and Irish Lions tour of South Africa.
Chiefs chief executive Michael Collins says it's great to have McMillan signed with the club for a further two years.
"Clayton has a great record of results from coaching the Bay of Plenty Steamers and the Māori All Blacks," says Collins.
"He is a proven leader who understands our Chiefs culture. Clayton and [Gatland] have formed a good working relationship and this combination is going to be fundamentally important for the growth and development of our club."
Gatland is "absolutely delighted" to have McMillan continue in the coaching group.
"He is extremely well respected in the game and what he has achieved with Bay of Plenty and the Māori All Blacks gives him the credit he deserves coming into these roles as head coach for this season and continuing as assistant coach when I return."
McMillan - who will continue in both of his current roles with Bay of Plenty and Māori All Blacks - says he's grateful for the opportunity to continue his journey with the Chiefs under the tutelage of the experienced Gatland.
"Personally, a significant attraction for me coming to the Chiefs was to have the opportunity to work alongside Gats," says McMillan.
"He is one of the world’s most successful coaches. I have always been a head coach, so in many respects I will relish the opportunity to step back and be mentored by somebody of his experience and stature.
"It is only going to help me in my coaching journey and one I am exceptionally grateful for."
