Former All Blacks coach Sir Steve Hansen thinks getting former New Zealand and Crusaders star playmaker Richie Mo'unga back for the next World Cup is a good bit of business all round. 

Hansen's been on the ground in Japan at Toyota Verblitz, where Mo'unga's guided Toshiba to back-to-back titles in the top league. 

He told Jason Pine he's got no doubt the 31-year-old will hit the ground running, as Ardie Savea and Beauden Barrett, among others, have.
