Brian Whales' Wellington four, Shane Rogers from Palmerston North and Colin Cox from Wanganui East rounded out the A section top four.
The B section included Wanganui club sides Kim Herbert and Steve Goater and Russell Duggan's Durie Hill four, while an out-of-town team skipped by D Gibb rounded out the bottom four.
Coombe said while play was reduced by the rain on Sunday it was not plain sailing to take the title.
"Keith and I had to play Mark Noble and his partner in the pairs and managed to win, but Mark is a New Zealand rep who played in the disabled team at the Commonwealth Games on the Gold Coast recently, so he is no slug. And Peter and John played a very handy team too, so it wasn't easy," Coombe said.
