All Blacks and Crusaders centre Aaron Mauger will join Leicester after this year's Rugby World Cup.
The 26-year-old has signed a two-and-a-half year contract with the Tigers, which begins in December.
"My immediate focus is the Super 14 and getting selected for the All Blacks again," said Mauger.
"It's good to have this deal done so I can focus on that challenge."
Mauger, who has played 38 Tests, is aiming to return to New Zealand and the national team for the 2011 edition of the tournament on home soil.
He said: "As a family we are looking forward to having an overseas experience and this is probably the only opportunity we will get due to the ages of our children, as we would like them to start school in New Zealand, although our eldest will have to do a half year in Leicester.
"I'd also love to finish my career with Canterbury and if I'm still playing well enough possibly have a crack at the 2011 World Cup."
All Blacks coach Graham Henry added: "Aaron has been a very important member of the All Blacks for the past five years.
"He's a world class player and has also made a significant contribution as a leader both on and off the field. His decision making ability has been integral to the All Blacks success.
"The team wishes Aaron and family an exciting and successful time at Leicester and look forward to their return to make a further contribution to New Zealand rugby in 2010."
Mauger is currently out of action with a knee injury, but is one of 22 All Blacks currently on a conditioning programme and will rejoin the Crusaders in March.
