Home side Waikato was the final team to book its place in the semifinals of the New Zealand women's interprovincial at the Riverside Golf Club in Hamilton.
Waikato defeated Canterbury 4-1 in a virtual quarterfinal yesterday to book its place in the final four for the first time in two years.
Waikato will play Auckland in the first semifinal, and Bay of Plenty will square off against North Harbour in the second.
Bay of Plenty beat Hawkes Bay-Poverty Bay 3-2 to finish as the top qualifier from division two.
On the other side of the draw, Auckland and North Harbour, which had both advanced to the semifinals after round six, played each other in round seven.
North Harbour caused one of the boilovers of the week as Ela Grimwood played superbly to end the 21-game winning streak of Brittney Dryland.
Waikato No 1 Hana-Rae Seifert, who has battled this week on her home course, came up with the goods when it mattered most as she defeated Amelia Garvey 3 and 2 to get her team home against Canterbury.
Bay of Plenty, 17-time champion in the event, will look to win the title for the first time since 2007.
Auckland, looking to win its fourth title in succession, and repeat the history of 1978 at Lochiel, will begin the final day as the overwhelming favourite despite yesterday's loss.
The semifinals are this morning, and the final is this afternoon.
Otago will play for 13th place after a tough day against Wellington, losing all five games.
At the top of the order, Jo Hicks-Beach and Sally Shaw found to their detriment that pars were not good enough and they had needed several birdies to stay in contention.
No 3 Abigael Crawford fought hard throughout but was dormie 4-down against Te Rongopai Clay.
She fought hard, winning the next two holes, but the match finished on the penultimate green.
It was no easier for the Otago tail, with Rachel Lissaman and Robyn Chambers both suffering losses.
Chambers had a close tussle against Emma Hayward, going out in 38 to turn square. She lost the 11th hole but squared the match on the 15th green.
However, the 18th hole was her nemesis and not for the first time. Chambers could not prevent a Wellington clean sweep, losing the final hole and the match.
