New Zealand Rugby says it will respect the wishes of the stripper at the centre of the Chiefs scandal and won't re-open an investigation.

But the union has accepted an offer of help from sexual violence survivors advocate, Louise Nicholas after she and other prominent women penned an open letter saying a toxic culture had developed.

The stripper, known as Scarlette, said she doesn't want the police or the rugby union to re-open the case and just wants to be left alone.

New Zealand Rugby CEO Steve Tew said he understands her position.

"I've been speaking to Scarlette's representatives. As I understand it from them, she wants the matter closed down. She doesn't want the police or us to revisit the inquiry and we'll respect. They are genuinely concerned for her."

Tew's admitting they have a long way to go to change the sport's attitude towards women.

The union is bringing in Ms Nicholas and Equal Opportunities Commissioner Dr Jackie Blue to educate players.

Tew said in this day and age, these attitudes simply aren't acceptable.

"Frankly, we're not where we would like to be so I've spent a bit of time talking to Jackie and Louise. We're going to bring them in and show them what we are doing, because we are busy in this area, but clearly there is more to do and there are some things we need to be doing better."

He said attitudes towards women leave a lot to be desired.

The integrity of the sport has been damaged, and outside help is needed to re-build that, he said.
