Investigators from China are to come to New Zealand to gather evidence for the trial there of a man charged with killing a taxi driver in Auckland last year.
Zhen Xiao, 23, is to stand trial for the murder of Hiren Mohini in China. He was detained in June in Shanghai.
Mr Mohini, 39, a father of two, was stabbed to death in View Road, Mt Eden, early on Sunday, 31 January, 2010. The killing was described at the time as a frenzied attack.
Detective Senior Sergeant Hywel Jones says a team of investigators from China is expected to be here within the next three to four weeks.
They will examine at the evidence, possibly speak to witnesses and taking key exhibits back to China.
A date for the trial is yet to be set, but a formal assurance has been given that the death penalty will not be imposed.
New Zealand has no extradition treaty with China.
