Seven combos returned from from afield of 24 for the second round.
Annabel Francis, of Canterbury, stood out as she willed her 10-year-old German import mare, La Quinara, to clear the first round.
Daniel Blundell (Athena NZPH) and Drew Carson (Winston V Driene) emulated the feat of the 15-year-old who had withdrawn from tomorrow's Hoy Show marquee Olympic Cup class after a mishap on Wednesday.
Taranaki based Nakeysha Lammers, on Resolution, sat on just one time fault behind the trio.
Francis, who has relocated to Taupo to be close to her trainers, Helen McNaught and Duncan McFarlane, collected a four fault.
However, Lammers produced a clear to pile the pressure on Blundell but Athena NZPH didn't let down the Waitemata rider to yield another clear round in a crisp time of 63.86s on a course Werner Deeg, of Germany, had designed. Athena is an Ocean Beach-bred mare.
Lammers finished second and Francis had to settle for third despite posting a crisper jump-off time of 60.77s.
