Northland hadn't been required to score more than 150 during the competition and it showed as they struggled to maintain the required run rate and keep wickets in hand.
This was despite the big effort from Condon, who backed up his four wickets with a well made 55, and contributions from Jakicevich-Roberts (20), Ben Litchfield (16) and Sam Lints (15).
Logan Tindall (3-21) was the pick of the Waikato Valley attack as Northland were dismissed for 142 in the last over, 19 runs short of their target.
Northland finished the tournament in fourth position behind Hamilton Gold, Bay of Plenty Coastlands and Waikato Valley.
