The father of All Black partner Teagan Voykovich says his family are shocked at revelations about Aaron Smith's toilet tryst and his daughter is just trying to get through the ordeal.

"Teagan is doing as well as can be expected," Michael Voykovich told the Herald today.

"Don't want to comment too much - it's for her to sort out in private."

He added that as Teagan's father, "it was a real shock to hear what happened. But I don't want to say anything that's going to affect the process they are going through."

Smith is understood to be travelling back to New Zealand after being handed a one-match ban by All Blacks management after it emerged he had taken part in an incident in a disabled toilet at Christchurch Airport with a woman who was not his current partner.

Witnesses said the pair were in the cubicle for several minutes as the team prepared to fly out to Argentina on September 18.

"The pair were in the bathroom for 5-10 minutes and from the noises coming out of the bathroom there was absolutely no questions what the couple were doing in there," the witness said.

A tearful Smith fronted media last night from the team's hotel in South Africa, apologising to Ms Voykovich, their respective families and All Black fans.

He admitted he'd made a "huge mistake" and that his behaviour was unacceptable.

He faces a misconduct hearing when he returns.

New Zealand Rugby has requested privacy on behalf of Smith's distressed partner.

Meanwhile, employment lawyer Susan Hornsby-Geluk said she didn't believe Smith's actions would or should lead to a dismissal.

"I think that as a person in a high profile position, there are increased obligations to protect the image and reputation of the All Blacks, but as a one off offence I wouldn't say that it was a sackable offence."


She thought it was more likely it would lead to a warning.

"To lose his position over a one-off brain explosion is too harsh and it's more likely to be a warning that would be appropriate.

"If it was any other person in any other job pretty much in New Zealand, it's unlikely that we would be looking at anything of this nature. It's just that there are expectations on All Blacks which are arguably out of proportion with the job that they actually do.

"We're not necessarily talking about highly educated people who have been trained in a professional environment to think about things like that ... at the end of the day, they're rugby players. They happen to be the most famous rugby players in the world, but they're still just rugby players."
