The size and quality of the field of women in the 100m race intrigues Potts.
"I have eight girls in the 100m field who are clocking under 12 seconds," he says.
Zoe Hobbs is fourth on the New Zealand women's all-time list for the 100m, surpassing the record of Hawke's Bay teenager Briar Toop, posted in 1990 at the Auckland Commonwealth Games.
The 19-year-old from New Plymouth, who is based in Auckland to train with former national 200m champion James Mortimer, clocked a PB 11.53s at the IAAF World U20 Championship in Bydgoszcz, Poland, last August.
"Zoe's going to be up against Christine Wearne, of Australia, who was here at our classic last year and went on to finish runner-up at the Australian nationals," he says.
Bay's Georgia Hulls and fellow NZSS stablemate Lucy Sheat, of Blenheim, who is officially the fastest schoolgirl over 200m, will relish the test.
Singaporean Veronica Shanti Pereira has the fifth fastest time of 11.8s, a shade slower than Sheat and Hulls.
In the men's 100m, 11 in the field have run under 11 seconds and one of them, Joseph Millar, of Taurnaga, has a scorching time of 10.3s.
Millar scooped the 100m, 200m double at the classic last year.
An Australian contingent, which Sir Graeme Avery again is sponsoring, will continue its trip here to add to the foreign flavour while travelling to other meetings in the circuit.
