In the morning, Otago No 1 Jo Hicks-Beach got off to a flying start chipping in on the first hole to take an early lead.
Maraea Durie was level with the card to lead Hicks-Beach by one at the turn but Durie then won 14 and 16 with birdies before finishing off the match on the 17th green.
No 2 Abigael Crawford was the only Otago player to register on the scoreboard despite turning 1-down.
Crawford made a timely birdie on the 17th using a Texas wedge from the apron to get back to square with Leanne Brown and the pair halved the final hole.
Tracey Storer struggled at times and was always behind Manawatu No 3 Tara Raj, eventually losing 6 and 4.
Annabel Evans started well but could not maintain momentum and turned 2-down to Katherine Paskins before struggling to keep the ball in play and losing on the 14th green.
No 5 Susan Greig paid the price for a slow start and was playing catch-up after turning three behind Tania Hook.
She fought back to trail by one with two holes to play but the match finished when Hook made an impressive birdie on the 17th.
After disappointment in the morning, Otago made a more determined effort against North Harbour in the afternoon and the match was tied 2-2 at the turn.

But she lost 17 to a birdie and the final hole to a par to halve the match.
Crawford and Storer struggled against their Harbour opponents, both players losing on the 12th green by resounding 7 and 6 margins.
