As conditions improved and the Bay began to bring their backs into the game, Brad Armstong and Josh Honey put the Bay side in a great position. When Counties were penalised, the Bay secured the ball from the lineout and, with the momentum of several drives, 125kg substitute prop Sammi Veikoso went over.
Reece MacDonald converted from out on the left to bring his points total for the tournament to 30 and making the half time score 12-7.
Bay of Plenty put themselves even closer when MacDonald kicked a penalty in the first minute of the second half and he then put his side 13-12 in front in the 44th minute.
Counties hit back from a 5m scrum after MacDonald's clearing kick from behind the try line was charged down, the try being awarded by the TMO. Arataki's Paea Lavaka showed his strength to go over after the Bay lineout following a penalty with MacDonald again accurate and the lead once more changed hands.
It was short lived, though, and a trio of Leger penalties put Counties eight points in front.
When the Bay lost a lineout and Tukania scored his second, a fine solo effort, the chance of another comeback seemed remote and eventually impossible.
MacDonald added 10 points to his tournament score, bringing it to 38 in three games.
