Millbank and Butler in today's quarter-finals will come up against another formidable pairing, in tomorrow's singles finalist Wellington's Leigh Griffin and her Nelson-based daughter Kirsten.
Other leading pairs to be eliminated included last year's champion, Ann Muir, and her new lead, Kensington club-mate Jude Ganley, the strong Auckland combination of Karen de Jongh and three-times national champion, Bev Crowe, and tomorrow's other singles finalist, Elaine McClintock and her Bay of Plenty skip, Marilyn McLeod.
In probably the most crucial match of the day de Jongh and Crowe lost narrowly to another of the more fancied line-ups, the Boyd sisters Mandy and Angela.
As well as Kirsten Griffin, another two promising younger players, Commonwealth Games representative Serana Goddard and Canterbury's Talya Bruce, also qualified.
Bruce and her provincial team-mate Sheryl Pearce had a 17-9 win over last year's singles champion, Helen King, and her lead, Birkenhead's Reen Stratford, while Goddard and her Carlton-Cornwall club-mate Karen Hema, beat Orewa's Ann Pearce and Cindy Henley.
