Steve Hansen plays down 100th Test milestone

The upcoming Bledisloe Cup between New Zealand and Australia in Perth is set to be Steve Hansen's 100 Test in charge of the All Blacks but the 60-year-old said the focus is on emerging victorious in the weekend's encounter.

Hansen joined New Zealand as an assistant coach in 2004 before heading the coaching panel in 2012 and is currently eyeing a hat-trick of World Cup title when they head to Japan next month.

"I haven't even thought about it. They're all special," said Hansen, who will step down from the role at the end of the World Cup.

"Every Test match we play, I'm not big on milestones, I think let's enjoy it for what it is. It's a privilege of being given the honour of being head coach of the All Blacks, even if it's only for one Test.

"It's no different to a player. You strive to being the best you can be and if you play one test match, well that's better than the bloke who played none, isn't it?

"And if you hang around for long enough and you do your job properly you get to stay there as a player and it's the same as a coach."

The All Blacks had a slip up this year after managing a 16-16 draw against the Springboks followed by a defeat against Australia in Perth that saw them concede the Rugby Championship title.

A win on Saturday at Eden Park will help them redeem themselves ahead of the showpiece event as they will retain the Bledisloe Cup for the 17th consecutive time and Hansen is looking forward to the challenge.

"This is an exciting one because there's a lot on it," Hansen said.

"That's why they're called Test matches, they're going to test our resolve to step up to the plate and we'll learn a lot.

"We're going to get asked some questions about ourselves. This is the best challenge we could get prior to going to a World Cup."
