Guoquan Wu, also known as Laurence Wu, hasn't been seen since March 10 on Sainsbury Rd, in the suburb of St Lukes. His vehicle - a Hyundai Santa Fe with the licence plate number GSE162 - was found at Piha Beach car park two days later.
Searches have turned up nothing.
The 22-year-old University of Auckland student's parents and brother, Lucas, flew to New Zealand from the family's home city of Guangzhou, in China.
