UPDATED 5.41pm Allegations by the stripper Scarlette against the Chiefs cannot be substantiated, New Zealand Rugby boss Steve Tew says.

LISTEN ABOVE: Sports lawyer Garth Gallaway and New Zealand Rugby Players' Association head Rob Nichol spoke to Larry Williams

In an interview with Radio New Zealand last month Scarlette told of "a pack mentality'' among the players.

Radio NZ did not air the full interview at the time but today released more of it, in which she made further allegations.

Scarlette alleged one player touched her vagina "multiple times with me telling him not to and eventually having to fight him off". She continued, "that didn't deter him though - he kept going.

"Then during all of that they just crowded in on me, real pack mentality kind of a thing."

She alleged the players tried to pull their penises out, "which I don't do".

"They were throwing gravel at me during the time as well. I'd normally stop just from that but I felt that I couldn't stop because I've been in situations before where I've been held in rooms and a knife held to me and I just didn't want this one to go that way.

"If you show your vulnerability they do attack it."

Tew fronted media at FMG Waikato Stadium ahead of tomorrow night's All Blacks game there, saying he stood by the investigation by employment lawyer Keith Binnie into the scandal.

Tew said Binnie trawled through more than three hours of video footage from the function last month and interviewed everybody there and he could not reconcile the two differing accounts of the event.

"We tried very hard to talk to Scarlette at the beginning of this inquiry.

"We talked to police, Victim Support, and a range of other people and it wasn't until the very end that she was prepared to speak.

"But actually she couldn't tell us anything that she hadn't already said on television."

Tew was adamant the report by Binnie was the "truth of the situation".

"We got to the truth of what happened around the Chiefs 2016 event."

The inquiry concluded that although the performance was legal and consensual, it was wrong for professional rugby teams to engage in such events and said players had to take collective responsibility.

Well-known sports lawyer Garth Gallaway told Larry Williams the integrity of the investigation is in major question.

"It's difficult for the public to have confidence in it. In the process, the next thing of concern is the independence of the investigation that's been undertaken."

New Zealand Rugby Players' Association chief executive Rob Nichol told Larry Williams in hindsight, an independent investigation may have been better.

"They're listening to some very respected people like Louise Nicholas etc. Should there have been some independence involved, quite possibly. But I make it clear, the findings were quite clear and they were supported by a large number of independent eye witnesses."

Police want to interview Scarlette after the fresh allegations emerged today.

A spokeswoman confirmed given what had been reported today they would again see if there was any information she wished to give police.

Police today said they had twice approached Scarlette after she raised concerns about the behaviour of players at the end-of-year rugby function. 

At the time she was offered further information and support by police. However, based on those discussions, which included consideration of her wishes and the information available to them, police were not able to take the matter further. 

"Given what has been reported in the media today we will again see if there is any further information she wishes to provide for police to assess," said the spokeswoman.

Scarlette, sent a statement through her lawyer that said she did not want the matters reinvestigated and she didn't want to lay a complaint with police. Scarlette said she wanted to be left alone and have her privacy respected.

"Scarlette has no wish to see the events surrounding the Chiefs end-of-season celebration re-investigated, either by NZR or any other agency.

"She did not make a complaint to the police at the time and she does not intend to make a complaint to the police now. She wants to be left alone and, once again, she asks media to respect her privacy."

Tew last night admitted the scandal had not been appropriately dealt with.

His comment followed the release of a letter signed by a group of prominent New Zealand women that urged the game's administrators to tidy up their act.

The open letter to New Zealand Rugby was signed by 25 women, including Equal Employment Opportunities Commissioner Dr Jackie Blue and Race Relations Commissioner Dame Susan Devoy.

Tew last night acknowledged "recent events show we have not got it right".

Today the NZR announced it would work with anti-sexual violence advocate Louise Nicholas.

Tew said he had been talking to Nicholas and Dr Blue over the past 24 hours and had arranged to "get them in to give us some assistance".

He said it was too early to say what kind of advice or training the women would give NZR.

"This is not something we can fix overnight.

"We are going to have to do some serious work but we are just welcoming her and will probably talk to some other people to see what advice we can get."

He said any work they did with women's advocates would have to be "quick" to avoid rugby's reputation eroding further.

Tew said if there was anything more the NZR could find out about the incident it would, and anything illegal would be handed straight to police.

He added that the Chiefs players themselves were remorseful.

"There are a lot of players who are upset because clearly no-one wants this to be dragged out.

"And I think a lot of us are feeling for Scarlette because this has put her in a very awkward situation too."

Tew said the players had already said sorry for what they had caused.

“We are very concerned for Scarlette’s wellbeing and I’ve offered any support that we can give her. I think the whole game, and I’m the representative of it, can say we are very sorry we’re in this position. If we’ve hurt either of these women then we apologise.”

Tew was referring to another women named Laura who made similar accusations about a Chiefs event last year.

When questioned about the way the apology was handled, in that the Chief’s reputation and rugby’s brand and players were put ahead of the strippers, Tew said there was good reason for that.

“We have accusations that were made which are damning and actually criminal that cannot be substantiated. The accusations were made live on television without any filtering of those accusations.”

He denied that the investigation into allegations about last year’s event had completely failed and said instead it was incomplete.

“No we haven’t talked to Laura and if she wants to talk to us we will. She’s now telling us she’s available to speak to us.”
