Keefe splits his time between homes in Thames and Raglan, training in Hamilton with the gym. He's aiming to get down to 130kg by fight night.
Most of Keefe's fitness work has been done on the farm and pig hunting. Now, he's in the gym most mornings and evenings to prepare for the fight.
The down-to-earth Kiwi bloke has a blended family of seven kids between him and his partner Sheryl Ngamata and he said the kids "think it's pretty cool".
But he said Sheryl took a little longer to come around to the idea.
"At the start she thought it was a joke, but now she has watched the training, she realises there is quite a bit of technique, but thinks I'm too old."
He said the training has been harder than expected but coach Winston Broadway has eased him into the training schedule.
He's focused on a win and becoming the champion of the Coromandel. "Nerves are not a thing, just focus on the goal, winning, especially on home ground."
Brown Buttabean controversially won his fight against Loni Uhila aka the "Tongan Bear" at the Fight for Life bout at Claudelands Arena late last year.
Chaos on the Coromandel features an undefeated title fight; a show down between two top welterweights - Cairo the Waikato Warrior George vs Nort the Assassin from Siam Bauchamp - along with the fight between Brown Buttabean and Tamati Keefe.
