Berridge dreams of one day fighting for a world championship.
And with just one loss in his 22 professional bouts (20(16)-1-1), and his new deal with Duco Events, he's on target to keep that hope alive.
"Having the guys at Duco show faith in my long-term future is a massive boost for me," Berridge said.
"They have supported me in the past by allowing me to fight on their cards so it was a no-brainer when the offer came in from them.
"They are in boxing for the right reasons.
"Everyone can see the great job they have already done with Joseph Parker.
"Now it's up to me to work hard and make sure I put myself into a position where they can help me get to the very top of the boxing world."
Lonergan and Higgins have long admired Berridge.
"The guy has everything a promoter wants from a fighter," Lonergan said.
"He has impressive KO power, a never-say-die attitude and a level of determination that suggests to us that he can go all the way in this game."
Berridge will debut as a Duco Events' backed fighter on the undercard of the October 12 Hydr8 ZERO Joseph Parker v 'King' Afa Tatupu title fight at Trusts Arena.
His opponent will be a NZPBA Super Middleweight title holder, Adrian Taihia.
