Denyer beat out fellow nominees Tracey Grimshaw, Amanda Keller, Jessica Marais, Andrew Winter and Rodger Corser.
The host, who also won Most Popular Presenter, had his wife Cheryl by his side to celebrate the emotional achievement.
The emotional host then spoke lovingly of wife of eight years, Cheryl, and their two daughters, Sailor and Scout, and thanked Cheryl for sticking with him through the 'best and worst times.'
'To my beautiful wife, Chezzi. Oh my God, we did it, darlin'. We did it! We b****y did it. We are an incredible team and I want you to share in this.
'You've been there to hole me up when I wasn't so great. You believed in me when I didn't believe in myself and you made the two most beautiful girls, Sailor and Scout.'
He concluded his speech by saying: 'I've said 'survey says' 30,000 times in the last four years. But for the very last time. Survey Says, thank you for making this your top answer.'
Before the big win, Denyer spoke exclusively to New Idea about what winning Gold would mean to him.
'Winning tonight would be a great underdog story, it would be a great way to send off the show. It’s taken on a life of its own that I didn’t expect the last few days,' he said.
'Feud has been really great, but TV show’s come to an end and then something magical has come along as a result of that.
'Game of Games is going to be monumentally large and so much fun. I can’t wait to meet Ellen,' Denyer said of his upcoming project, Ellen Degeneres' Game of Games.
'We’re going to be working together pretty soon on that. She’s been in Uganda working on a conservation program with gorillas but she’s now back on the ground now. We’re hoping to meet up real soon. I can’t wait to meet her, my head will explode when that happens.'
