With his partner groggy, the teammate fought defensively for the rest of the round and the first half of the third, as Makatea-Leylander began winging punches to try and press the advantage.
The Waikato team recovered and got back to their game plan, as a tiring Makatea-Leylander nearly slipped over a couple of times, while Kapi became the designated fighter to start each of the remaining three rounds.
They had their moments, but the Waikato team picked up the pace again and delivered hard jabs and knee strikes, while grappling back to their corner to cut off any visitor momentum.
"Gutted on outcome, my gas tank wasn't at its best – so much going on in my life at the moment, [my] mindset's been all over the place," Makatea-Leylander said on Facebook, referencing the fact the koro of his partner had died during the week.
"No excuses, I'll come back stronger."
There was better news on the undercard as fellow Assassins gym member Swade Wallace was victorious in his second kickboxing fight.
Wallace picked up a TKO victory in the third round of his 80kg bout with Tauranga Martial Arts gym member Matu Ririnui.
