The defending Auckland women's tennis champion Zheng Jie of China will return to defend her ASB Classic title.
The confirmation of the world no. 26 means there are now five players in the top 30 confirmed for the tournament.
Zheng's win in Auckland earlier this year was her fourth singles tour title.
She has 14 WTA doubles titles including two Grand Slams at the Australia Open and Wimbledon in 2006.
The tournament runs from December the 31st to January the 5th.
