The point-less day, team-wise, dropped HBPB to 10th on the 11-province table.
They ended on 1½ team points and 10½ individual wins. Behind them were Taranaki, in stark contrast to their men's team who won the men's national interprovincial the previous week.
HBPB women's other win yesterday was provided by No.5 Kayla Van De Ven, a 2-up win against BoP.
HBPB were to be back in action this morning in a playoff for ninth and 10th against Aorangi.
The teams drew 2½-all in their Round 5 clash on Thursday. McDonald comfortably won her match in that tie and another win today would give her a record of five wins and two losses (both on 18) for the week — the same as last year's performance.
In this morning's semifinals, top qualifiers BoP were to face Canterbury while Waikato were up against Northland.
Missing from the tournament due to Covid-19 restrictions are Auckland and North Harbour. Auckland have won the past five national interprovincials.
