A leading law specialist says a Malaysian diplomatic accused of sex crime could - if convicted and given a custodial sentence in New Zealand - do his time back home in Malaysia.
Associate professor of law at Auckland University, Bill Hodge, agrees with that scenario but says there would have to be some delays.
"The New Zealand government won't want to be seen to be sending him back to serve his time in Malaysia just prior to the September election," Prof Hodge says.
"It makes sense, but later in the year."
Prof Hodge says the last thing John Key would want is to look like former Labour Prime Minister David Lange, who allowed Rainbow Warrior bombers Alain Mafart and Dominque Prieur - both French army officers - to serve their manslaughter sentence in Tahiti.
