"Julian goes with our blessing and we know that French rugby fans will quickly embrace him as their own. We thank Julian for his contribution to rugby in New Zealand and we wish him and his family well for their move to Toulon."
All Blacks Head Coach Steve Hansen said "Jules can be incredibly proud of everything he has achieved in the black jersey. He is a devastating ball runner who inspired others with his physicality and try-scoring prowess. On behalf of all the All Blacks, we want to wish Julian and his family all the very best and thank him for everything he has done for the All Blacks."
The 27-year-old championship winning Hurricanes wing, has played more than 120 matches for the Hurricanes since making his debut for the Super Rugby Club in 2011, a year after he made his first start for Wellington. His performance saw him selected into the All Blacks the following year.
Hurricanes head coach Chris Boyd said Savea and his family would leave the club with its 100 per cent blessing now they had decided it was the right time to go.
"For me, Julian has been one of those guys who has been a one club, one province man who has always given everything he has for Ories, Wellington, the Hurricanes and New Zealand rugby.
"He has always put his heart and soul into it and we respect that greatly."
Wellington Rugby Football Union CEO Steve Rogers was also quick to recognise Savea's contribution to the sport in the capital and wish him the best for the future.
"Julian has always done what he can to help Wellington and has been an important leader both on and off the field for the only province he has ever represented," he said.
"While the opportunity to pull on a Lions jersey was limited during his long All Blacks career, he always wanted to play and be part of our campaigns when he could. I'm sure Toulon will benefit greatly by having him in their club.
"We know Julian was really looking forward to being part of the Lions in 2018 but we fully understand the opportunity that has presented itself in France so we wish him all the best."
