New Zealand coach-in-waiting Scott Robertson has named former Munster player Jason Holland among his backroom staff but Joe Schmidt is heading out the door.
Former Ireland head coach Schmidt joined Ian Foster's staff in June 2022 but will not be kept on when Foster steps down at the end of the 8 September - 28 October World Cup in France.
Robertson will retain Jason Ryan as forwards coach, reviving the partnership that built a dynasty at the Canterbury Crusaders.
Ryan left the Crusaders last year to join Foster's staff at the All Blacks and will continue in the role.
Robertson appointed Ryan at the Crusaders in 2016 and the pair oversaw the Super Rugby side's run of six championship trophies in six years.
"Any role coaching the All Blacks is a huge honour and for as long as I have the opportunity to contribute to the legacy, I will do that to the best of my ability," Ryan said in a New Zealand Rugby statement on Wednesday.
"My full focus right now is Rugby World Cup, but I look forward to continuing the journey in 2024 and beyond."
Ryan will be joined by assistant coaches Leon MacDonald, former Munster player Holland (below) and Scott Hansen, who take up their All Blacks roles in 2024.
Current Auckland Blues coach MacDonald will lead the attack with assistance from Wellington Hurricanes coach Holland, while Crusaders assistant coach Hansen will be in charge of defence.
Nic Gill, a key part of the All Blacks management group since 2008, will stay on as Head of Performance, New Zealand Rugby said.
"I've known Jason, Leon, Scott, Alfie (Holland) and Gilly for a long time and worked with them all at times during my playing and coaching career," said Robertson.
"They are a highly talented and motivated group who will bring different strengths to the table and who share a similar philosophy on the game.
"Like myself with the Crusaders, I know they all have important work to do in 2023 and their main focus will be on their current job in hand, but we will be ready to go from 2024."
Elsewhere, South African Rugby have retained the services of remaining members of their coaching staff up to the 2027 World Cup in Australia following the confirmed departure of head coach Jacques Nienaber and assistant Felix Jones later this year.
Nienaber will vacate his role after the World Cup in France, having agreed a move to Leinster as a senior coach, while former Munster and Ireland full-back Jones (below) joins the England set-up under Steve Borthwick.
But any thoughts their might be a mass exodus have been allayed with Bok assistant coaches Mzwandile Stick, Deon Davids and Daan Human all signing new four-year deals, and head of athletic performance Andy Edwards following suit.
"They have all come a long way as a coaching team under the guidance of Rassie (Erasmus), as director of rugby, and I am confident that the continuity in our coaching staff will bode well for the Springboks for 2023 and the following seasons," SA Rugby CEO Rian Oberholzer said.
"It was our ambition to retain all the current coaching staff in recognition of the excellent work they have done over the past six years regardless of the outcome of the Rugby World Cup later this year, and we are pleased that most of them have agreed to continue with the team.
"The planning to confirm a successor in the title role of Springbok (head) coach remains ongoing in the background, while Rassie's services are tied down to the end of 2025 at the very least."
The Boks open their 2023 season with a home Rugby Championship fixture against Australia in Pretoria on 8 July.
