Out of the anti-doping investigation gloom, Cronulla is seeing the first glimmers of financial renewal following management restructuring at the embattled NRL club.

The Sharks announced on Friday that apparel manufacturer Blades had extended its deal for a further season - the first piece of positive news since the start of the Australian Sports Anti-Doping Authority's (ASADA) investigation into the club's alleged use of prohibited substances began.

And they are hopeful of having a new stadium naming rights backer in place before the next home game against Canberra on May 19.

The Sharks' impressive off-season recruitment drive was expected to give them a genuine opportunity to end a 46-year wait for their first NRL premiership.

However the ASADA probe, announced in March, put all dealings with sponsors on hold and the team has been running out without a major front-of-shirt deal and playing in a stadium without a naming agreement since Toyota ended their relationship with the club in January.

But since the appointment of veteran administrator Steve Noyce as general manager of football and former Brisbane supremo Bruno Cullen as interim CEO, the club have been able to begin negotiating again with potential partners.

Patrick Woods, Cronulla's general manager of marketing and commercial, said the off-field re-structuring had made the Sharks more appealing to investors.

Woods hoped hoped to settle a naming deal for Sharks Stadium before the May 19 home game and was also confident a shirt sponsorship deal would be concluded soon.

"The people we have talked to have been very impressed with the infrastructure change since Steve and Bruno came on board," Woods told AAP.

"We also have Peter Legg, the former chief financial officer of the NRL joining as the general manager of finance."

The changes made at the club, at the insistence of the NRL, were followed swiftly by the departure of chairman Damian Irvine, who had insisted the club did not need a CEO.

Irvine was forced out after telling a newspaper that Sharks players had been given "horse drugs".

The comments followed the board's decision to stand-down coach Shane Flanagan and sack three members of his backroom staff.

Woods admitted it had been tough for his department, but the presence of Cullen, who was associated with the Broncos for over 20 years until 2010, has been a big attraction for businesses despite the cloud hanging over the club.

"They've been impressed with the governance Bruno has been putting in place," he said.

"Between the whole management here there is a lot of experience in a variety of codes.

"These things don't happen overnight but what we are seeing over the last six to eight weeks is that people are impressed with what we are trying to achieve."
