Current NRL chief operating officer and former NZRL chief executive Jim Doyle has been appointed as the next CEO for the club.
Scurrah's departure comes as a surprise, after he announced earlier this year that he would resign from his post if the Warriors failed to qualify for the 2014 NRL finals series.
That declaration followed former coach Matt Elliott's controversial departure in April, after a disappointing start to the season in which the side lost three of their opening five encounters.
Since then the Warriors have found form under new coach Andrew McFadden, winning four of their last seven matches since he took over the head coaching duties, and sit two points outside the top eight in 12th position.
Warriors club chairman Bill Wavish praised Scurrah for his contribution to the club, 2014 being his ninth season as chief executive.
"Wayne has worked very effectively for the club," Wavish said.
"During his time we have seen the Warriors improve across the full range of football and business activities and become one of the strongest clubs in the NRL.
"Wayne indicated some weeks ago his aim to step down at the end of the season. Jim Doyle was approached and we are thrilled that he has signed a contract to be the next Warriors Chief Executive Officer."
Scurrah says when he joined the club in November 2005 he didn't anticipate being in the role for nine seasons.
"When I started we had significant challenges both on and off the field," he said.
"The club is in much stronger shape and I would like to acknowledge the remarkable team of people who have worked with me during this time to achieve what we have.
"It's been a privilege to be in the role and I look forward to continuing to work with my team until I leave later this year.
"I would also like to publicly congratulate Jim on his appointment. I'm certain he will be a great asset for the club."
Wavish agrees: "The Board has every confidence in Jim not only as a proven businessman but also as a passionate stalwart of rugby league in New Zealand."
Warriors owner Eric Watson commented: "Wayne has done a professional job and I'm grateful for the passion and commitment he's shown during his tenure.
"The Warriors are about to complete their second decade which makes the next 10 years critical for the club. Jim's a highly successful businessman first and foremost but his understanding and connection with the game is a great asset. I'm hugely excited about Jim's appointment and the future of the Warriors."
Doyle said he was delighted about the role and returning to New Zealand.
"The Warriors club has a good reputation within the NRL based on the work that Wayne and his team have done in recent years," he said.
"I'm very excited about both the role and returning home to New Zealand. I am sure the next stage will be exciting and challenging, and I am committed to seeing us lift the bar even higher on and off the field."
Doyle will commence the role as CEO of the Warriors on November 10, 2014.
Scurrah's resignation follows an announcement from the club today that Mt Smart Stadium will be the club's Auckland home venue for the 2015 NRL campaign, confirming nearly all regular season games will be played there.
The announcement follows the Warriors' return to their spiritual home for their first game this year against Newcastle on Sunday.
The decision comes after the Warriors opened their 2014 programme with three home games at Eden Park against St George Illawarra, Canterbury-Bankstown and Canberra with a fourth against Wests Tigers played at Westpac Stadium in Wellington.
