All Blacks star's tearful apology over 'airport toilet sex'

All Blacks halfback Aaron Smith has made a tearful apology after being suspended for allegedly having sex in an airport toilet, breaching team standards.

Smith apologised to his girlfriend, his family, All Blacks team-mates and fans for his "huge mistake" after a couple heard the tryst from the disabled cubicle inside Christchurch Airport.

"My behaviour was unacceptable and if you could respect me and my partner in this situation. I'm just trying to get home to deal with this. Thank you," he said.

The 27-year-old has been stood down for this weekend's test against the Springboks in Durban.

In a statement, NZ Rugby Union asked for Smith and girlfriend Teagan Voykovich's privacy, given an unknown woman was involved in the tryst.

Witnesses had claimed Smith and the unknown woman entered the toilet within 30 seconds of each other.

The pair were inside the bathroom for about 10 minutes before Smith was seen adjusting his clothing leaving the cubicle.

Prime Minister John Key has weighed in on the bathroom tryst and said Smith's actions were not what society expected of a role model.

Coach Steve Hansen said the incident happened the day after All Blacks beat South Africa 41-13 on September 17.

Hansen said Smith accepted his behaviour was not of All Blacks standard and the punishment for the breach of team standards was decided by team leaders.

It’s understood Smith had asked to leave the tour, a request backed by team management.

It is not the first time Smith has courted controversy.

In 2012 he was benched for a Test against South Africa in Dunedin for breaking a team curfew and two years a later a naked selfie of him was circulated online.

NZ Rugby boss Steve Tew said Smith would face a misconduct hearing in New Zealand.

"This was really bad decision-making by Aaron which reflects poorly on him, and on the team," he said.

It's the latest incident NZ Rugby has had to deal with in recent times after a stripper scandal at a Chiefs end-of-season party and an assault case involving Wellington Lions player Losi Filipo.

"We are taking action to improve the culture of our game and are about to embark on an independent review of respect and responsibility in our professional player environment," Tew said.
