Qualifiers will be found in the women's pairs by the end of tomorrow and Baildon (winner World Junior Cup 2009) and Shirley will be jostling to find themselves a place among the bowlers entering the sudden death field of play on Monday.
But to earn themselves a berth the women will need to keep up the pace and stretch their leads after winning two games from three today by fine margins.
Clare McCaul (Silverstream), another New Zealand squad member, teamed up with Amy Brenton (Stoke) to overcome all opposition in their three matches on the Balmoral greens.
Meanwhile, in the men's pairs, the victories came thick and fast as Black Jacks Girvan and Delany brushed aside all challengers and joined New Zealand squad members Shannon McIlroy (Stoke), Andrew Kelly (Canterbury), Greg Ruaporo (Auckland) and Chris Le Lievre (Onehunga) among the qualifiers for sudden death post-section play on Saturday.
McIlroy is paired with fours defending champion Matthew Gallop (Cabramatta), while Kelly and Ruaporo form their own talented duo and Le Lievre has teamed up with former New Zealand representative Gary Lawson (Belfast) to make a play for the silverware.
The winner of numerous national titles, Petar Sain's (Carlton-Cornwall) team qualified along with former national representative Blake Signal's (Stokes Valley) and winner of the 2009 men's pairs title Rob Ashton's (Johnsonville) pairs.
Tomorrow from 8:30am the men return to the greens for a day of singles action to find the qualifiers among them, and the women finish what they started today with the final qualifying rounds in the pairs.
