Northland came close in the Shield contest, their runner-up finish the result of some late Bay heroics during round two.
Manager Michael Macdonald noted the critical moment came during the final stages of round two with the final approach shot by Bay number one Charlie Hillier.
"Charlie made birdie from the trees on the 18th hole to square his match with Kadin [Neho] and with it a 4.5-3.5 win for the Bay," Macdonald.
"A draw would have given us control of our own destiny, unfortunately that shot left us needing Waikato to win against the Bay and and us facing a must win match against Auckland in the final round."
With Bay of Plenty winning 5.5-2.5 over Waikato, Northland were left to rue another missed opportunity.
Earlier in round one Northland beat Waikato 4.5-3.5 with all eight matches going to the 17th or 18th hole.
Kadin Neho continued his recent run of good form going unbeaten with two wins and a half in the always difficult number one position.
Alex Neely, Sheldon Kearns and Luke Brown all picked up two wins apiece as did masters number one Saali Herewini playing at eight for the weekend.
