Guaging just where the Silver Ferns are ahead of their two tests against Australia is no doubt causing a few headaches for not only New Zealand netball coach Ruth Aitken, but also her Australian counterpart Norma Plummer.
Plummer was on hand to watch the Silver Ferns trounce England in two tests and fall apart in another in the recent 2-1 series win.
Silver Ferns captain Julie Seymour, who hasn't travelled with the side to Australia for the opening test in Melbourne, says the second test loss will no doubt have given Plummer plenty of ideas where to target the Silver Ferns.
She says they'll no doubt be as confident as ever, even though they're without experienced shooters Catherine Cox and Sharelle McMahon.
