Police have confirmed that the man found dead outside an apartment at the Chelsea Bay Residences on Rawene Rd in Birkenhead at about 4.30am on October 7 was Qiang Xin, 31.
A friend of the deceased man told the Herald Xin was the owner of a popular Chinese hot pot restaurant chain and was originally from China.
"Police have been liaising with next of kin in New Zealand," a police spokeswoman said.
"We are also aware that the deceased has family in China and the Chinese Consulate was advised by police of the death."
Police said a number of people have been spoken to as part of their inquiries which the Herald understands included the dead man's ex-wife and current girlfriend.
