Kattenberg finished runner-up in the second Pre-89 Post Classics race, crossing the line less than a second behind Coutts, with Lawrence settling for third.
"Lawrence and Coutts were going fast today. I pulled away a bit from Jay [Lawrence] in the first race and I was too scared to look back," Kattenberg said with a laugh.
"I can't afford to do the whole series but I simply couldn't stay away from Manfeild. I love this place," Kattenberg said.
"You could say Manfeild is my home away from home.
"I have a lot of good memories from here and I guess today there's a couple more."
Despite contesting just one of the two rounds so far, Kattenberg finds himself seventh in the series standings, just 10 points behind sixth-placed Vince Burrell of Hastings.
Coutts leads the class by eight points from Lawrence, with Paraparaumu's Sean Donnelly third overall.
"I've been playing around on motorcycles for years but I gave up the serious stuff about 20 year ago. However, this is a sport that you just can't walk away from."
Kattenberg was national TT champion in 1987 and also scored points in the World Superbike Championships in 1988 and 1989.
He hung up his helmet in 1992 and now, two decades on, he races a bike that was one of the best from back in his own golden era, a 1989 Yamaha FZR1000.
"I'm really enjoying racing again," he said.
"The difference now is that there's no real pressure on me to win. I don't have to prove anything to anyone."
