It is believed she travelled to and from China with her first husband, Andy Yang, who is the father of her daughter Leena. Chinese-born Yang now lives in Hong Kong.
But there was a two-year gap between her separation from Yang and her return to Asia on May 3, 2009.
On that occasion, she was following Gao. The documents show she entered China through the Gongbei Customs office near Macau. According to the documents, Hurring entered China alone and without her daughter. She had passed through Hong Kong before making the short ferry trip to Macau.
Then, over the next two years, immigration records show she passed through the Chinese border crossing near Hong Kong five times. On each occasion, she travelled alone.
Hurring returned to New Zealand in February without Leena, leading to speculation she is in Hong Kong. It was reported since that Hurring had given birth to a second child.
Hurring has pleaded not guilty and faces a trial in February.
