Onerahi-Central's left-arm pace bowler Dewayne Bowden has posed plenty of problems for opposition batsmen this season, but it was his bat which dominated play on Saturday.
Bowden struck a quick-fire 58 to give his side a comfortable win over City in the morning's Northland Cricket Association premier grade Twenty/20 game.
He followed this up by top-scoring with 67 in the afternoon's match against Kaipara Flats - cementing Onerahi-Central's place in the final as the top qualifier.
Although well beaten on Saturday, Kaipara Flats still finished second on the competition ladder and so will meet Onerahi in the final, which will be played at Cobham Oval on March 10.
In the other morning games, Zest Insurance Whangarei Boys' High School posted 136 for four wickets, led by David Armitt's 60 not out, to comfortably beat Maungakaramea who could only post 94 in their 20 overs. Kaipara Flats passed Kamo's total of 96 with three overs to spare, thanks to some big hitting from Ray Beamish and Kyran Dill.
