In the Men's Federation One Cup, Kerikeri Bay Builders moved closer to their sixth final in nine years with a 2-1 win over Albany Africans.
Goals from Timo Obrez and Jeremy Rintoul helped them to their quarter-final win.
Coach Mark Roberts said it was an impressive effort from Kerikeri, but now they needed to break their duck in the competition.
"They played really well, it was the best performance of the season from our guys. It was a well-deserved win," he said.
"We've made five Federation Cup finals in eight years and we haven't won one yet.
"We've got to get the monkey off our back. We're definitely good enough. We've beaten Auckland teams to get through to that final but it's just knocking it off that's been the trick.
"We've played Glen Eden Rangers the last couple of years and pushed them all the way but it's just about getting over that line.
"We have been building over the last three or four years and we've got a few youngsters playing for us each week so I have no reason to think we can't win it this season."
In the plate section, Kamo went down 2-1 to East Coast Bays Napoli.
