The newly appointed All Blacks coach Steve Hansen says taking over a World Cup-winning side only makes the role even more challenging.
Hansen, who's been Graham Henry's assistant for the past eight years, got the top job on Friday after Henry announced his retirement in the wake of the World Cup win.
The former Canterbury midfield back, who's carved out a niche as forwards coach, was the only candidate put forward for formal interview at the NZRU board meeting on Friday.
Often World Cup-winning sides struggle after their success and Hansen says he fully aware of what's in store.
