Should NZ have an extradition treaty with China?

Chinese Premier Li Kequiang has asked for a formal extradition treaty with China - seeking the return of 30 to 60 people living in this country wanted for fraud and embezzlement. John Key says he is not opposed to a treaty arrangement as long as it was for serious cases, and that people would not face torture or the death penalty. However human rights groups have said New Zealand could be sending people into danger if the deal goes ahead.
