Cody Andrews' day one heroics set up an easy second day for his teammates as Maungakaramea completed what was always going to be a comfortable win.
Andrews took six for 27 on day one as Kamo were rolled for 98, with Maungakaramea scoring 230 for seven on day one.
Captain Neal Parlane declared early on day two in an attempt to knock Kamo over early and leave Maungakaramea a small total to chase. And that's exactly what happened.
Kamo managed 76 more runs than their first innings as they went on to be bowled out for 174, with Joey O'Sullivan the pick of the bowlers with three for 41, leaving Maungakaramea needing only 22 runs to win.
City couldn't hold off Kaipara Flats in their encounter after trailing by only two runs after each team's knocks.
Kaipara resumed the day on 147 and kicked on to 167 for nine before declaring with a slim lead over City.
However, City couldn't break the stalemate and were bowled out cheaply for 55, leaving Kaipara only 53 to win.
Matt Taylor was the pick of the bowlers with his four for 10, complemented well by Kevin Forde, who claimed four for 11.
Chasing 53, Kaipara's opening batsmen did the damage as they reached the target with only one wicket down.
In Whangarei Boys' High School's match, they were left demoralised by Onerahi on the second day, as they went down by an innings and 71 runs.
