The second fight of his 2015 comeback, with a third scheduled against Australian Rob Powdrill in October, Berridge also embraced the familiar feeling in the gut.
"I'm always nervous. If you're not nervous, something's wrong.
"It's 100 years of Anzac. Learning about my grandfather and great grandfather, it's great to go to war on Anzac."
His cousin and event co-organiser Paul Berridge confirmed on the night that 400 general tickets had sold along with the 400 corporate seats.
He and his partners were hoping to attract a decent crowd to the public weigh-in at Majestic Square yesterday afternoon in order to attract a good walkup for the 500 remaining seats.
"We definitely will showcase the biggest boxing event in Wanganui history," said Paul Berridge.
"This fight is good enough for Sky Arena, in my opinion.
"It doesn't have to be Wellington and Auckland. This is our [Manny] Pacquiao versus [Floyd] Mayweather."
The terms were also friendly between Taranaki's Daniel Maxwell (3-28-1) and the Wellington challenger for his NZPBA light middleweight crown, Blake Bell (0-1).
After winning the belt in February, although losing two non-title fights since, Maxwell said while he had the choice of three shows to appear at this weekend, one in Australia, he always wanted to appear on a card headlined by "The Butcher" Berridge.
Given a choice of opponent, Maxwell has been swapping text messages with Bell since Christmas to try to get the two of them together.
While Bell has a career outside the ring, he said boxing was what kept him going, as it got him into the best shape of his life.
"I'm here now, I'm putting in the work, and ready to show what I got.
"I plan on pushing the pace and hopefully I can get the win," he said.
As a journeyman fighter with over 60 amateur and professional bouts to his name, Maxwell was relishing the chance to be fighting a champion on a major card.
"It means the world. I've had a lot of ups and downs.
"I believe I've fought the best and I'm ready for this test."
As well as overall experience, Maxwell is conditioned for a championship-length bout as four of his previous fights have also been 10-round affairs.
"You've got time to work things out. They can go fast or they can go slow - that's what it's about."
Bell admits all he has been able to do is hard sparring to prepare for going that distance.
"I'm pushing myself to the limit when I'm training."
Yesterday, Robert Berridge and Andy Robinson each tipped the scales at 79kg, while Maxwell weighed 69.6km and Bell was 68.6km.
The other professional fight this evening will be a four-round light heavyweight match-up between Wellington's Angus Lyndsey and Napier's Tipene Manipoto.
Tickets are available until 12pm today from Stellar Restaurant and Fight Fit Gym for $35. On the door will be $45, with the doors opening at 6pm.
