“Coaching the All Blacks has been the honour of my life,” he said.
“I am incredibly proud of what this team has achieved and of the progress we have made. We have brought through a talented group of young players, strengthened the depth across the squad, and set solid foundations for the years ahead.”
The All Blacks were also beaten for only the ninth time in their 120-year rivalry with England when Steve Borthwick’s side claimed a 33-19 victory in the Quilter Nations Series in November.
New Zealand Rugby (NZR) said the process of finding a replacement for Robertson, who was contracted to the end of the 2027 World Cup in Australia, will start immediately.
The chair of the governing body, David Kirk, thanked Robertson for his contribution to the team, adding: “As always, he has continued to put the All Blacks first and we respect that he has done the hard but right thing in agreeing to depart.
“His passion for the team as both a player and coach is evident and his commitment to and involvement in rugby in New Zealand at every level over a long period is significant. We wish him well for the future.”
Kirk said the mid-point in the Rugby World Cup cycle was the right time to take an “extensive look” at the All Blacks’ progress under Robertson on and off the field before a packed Test calendar in 2026.
New Zealand host France, Italy and Ireland in the Nations Championship in July followed by a trip to South Africa for an eight-match tour in August and September.
They then face Australia home and away in the Bledisloe Cup in October before travelling to Europe in November for more Nations Championship matches, this time against Scotland, Wales and England.
