Halfback Davies brushed aside some weak tackling to score and a simple penalty reduced the Bay's lead to 14-8.
Worse was to come just on halftime when the Bay dropped off more tackles to let first-five Mike Stanley cross for a try he immediately converted.
Up 15-14, Auckland started the second spell as they finished the first, putting pressure on the Bay defence which cracked again to allow winger Otulea Katoa to score.
Trailing 22-14, the Bay had second-five Malakai Kisna to thank for not going further behind. Davies sprinted 50 metres to beat the cover defence but as he crossed the line to get closer to the posts, Kisna blindsided him and knocked the ball out of his hands. The reprieve galvanised the Bay into action and they were right back in the game when Kisna swooped on an Auckland pass and ran away to score. Ishimori converted, then added a penalty to put the Bay in front 24-22 with 10 minutes to play. Auckland finished stronger and after a concerted wave of attacks at the Bay's line, a gap finally opened and Teddy Stanaway dived over to win the game for the visitors.
