All Blacks star Smith stands down from Bledisloe Cup clash

New Zealand scrum-half Aaron Smith will not feature in this week's Bledisloe Cup match against Australia after "voluntarily" standing down following a disciplinary meeting with the All Blacks.

A misconduct hearing was held on Monday after Smith was suspended for "breaching team standards", having been embroiled in revelations about a toilet incident with an unidentified woman at Christchurch airport last month.

And following the hearing - which lasted over two hours - Smith received a formal warning with his actions deemed to be "serious misconduct" due to the impact on the All Blacks' image and brand, while he stood himself down from Saturday's showdown against the Wallabies at Eden Park.

The 28-year-old - who missed New Zealand's last Test against South Africa after the story broke - also forfeited his selection fees and is "committed to getting the support he needs to deal with personal issues and to work on his relationship with his partner."

"It's important to note that as an employment matter, it is not usual to comment publicly on proceedings. However, both Aaron and his legal representative, and New Zealand Rugby acknowledge that in the circumstances, there is a need to make some public comment," New Zealand Rugby general manager Neil Sorensen said in a statement.

"Aaron presented himself as genuine, honest and incredibly remorseful.  We have also taken into account the fact that the very public nature of this incident, has had a significant impact on him personally.

"We accepted that he is genuine about wanting to improve himself and note that he himself has acknowledged he will need the support of his family, friends and Rugby to move forward.

"We also noted that Aaron had already made a very public apology to his partner, friends and family, team mates, his employer, and rugby fans and he had already served a one-week stand down."
