NRL chief executive David Gallop hopes Melbourne Storm players will co-operate as the league comes knocking on their doors next week for further investigation into the club's salary cap rorting.

Gallop confirmed league salary cap sleuth Ian Schubert is set to interview several Storm players over the contract duplicity which saw the club stripped of its two premierships and made to play for no points this season.

The recent Deloitte report commissioned by club owners News Limited found no evidence to support that any players knew about the salary cap cheating.

But Gallop made it clear after meeting with Storm players and staff on Thursday for the first time since the hefty penalties were handed down four months ago that the league's own investigation was continuing.

And he said some Melbourne players could expect a tap on the shoulder from Schubert once their season is completed following Sunday's home match against Newcastle.

"There's some interviews our salary cap team want to conduct down here," Gallop said.

"It's still important we complete our own investigation down here, and I expect that will happen fairly quickly.

"They (the players) gave no indication today that they won't be cooperating.

"It's a series of interviews Ian Schubert wants to conduct. I'm not exactly sure who he wants to speak to."

Gallop described his meeting with Storm players as a "worthwhile exercise" and left Melbourne believing he had "a positive relationship" with the club.

But he stood by the league's hefty penalties as being necessary to maintain the competition's integrity.

"There were many people down here who were merely passengers in a car doing 160km/h in a 60 zone," Gallop said.

"The mood was mainly positive. There were some forthright questions asked.

"I accept there are many people down here including the players, there are many people that were innocent victims of this.

"We talked about the penalties, the appropriateness of the penalties, and I 100 per cent believe the penalties were appropriate for what happened down here."

Storm chief executive Ron Gauci said he believed both the players and Gallop handled the meeting "respectfully".

"They asked the questions that have been on their minds for some time," Gauci said of the players.

"I thought the mood was good. It was handled very respectfully from all parties.

"It gives us the opportunity to have clarity in the answers to our questions ... and closure in many ways."

Gallop's meeting came just days before the Storm bring down the curtain on their difficult season.

Sunday's match in the 30,000 capacity AAMI Park is a sellout.
