World number 25 Elena Vesnina has withdrawn from The ASB tennis Classic with just over a week before the start of the tournament due to picking up an ankle injury.
Tournament organiser Karl Budge says German Julia Goerges now doesn't need a wildcard, which is a chance to award it to someone else.
"Now that Julia's in on her own right, we've got an additional wildcard now that we can have a play with.
"So it gives us a bit of scope to have someone join Andrea who we announced last week."
15-year-old Croatian Ana Konjuh is thought to be in line for the vacant wildcard.
She has a current ranking of 256 in the world.
