Doctors said Lockwood had a 60 per cent chance of surviving the transfer from Nha Trang to a better equipped hospital in Ho Chi Minh.
"He survived," said Turner.
Yet she said it was too early to know what impact the accident has had.
"If he comes out of the coma it's likely he will need many months of rehabilitation to get his body and brain to function as well as it can after the accident."
Lockwood has lived in Vietnam for the past few years with his Vietnamese wife and their son.
He set up the Kiwi Bar and restaurant last year and enjoyed hosting locals, expats and tourists.
Lockwood grew up in Palmerston North and went to Massey University.
