There's a push to introduce a no body, no parole law to New Zealand. 

Former prison guard David Benbow has been sentenced to life imprisonment with a minimum non-parole period of 17 years, for the murder of Michael McGrath. 

McGrath's body has never been found since he went missing in 2017. 

His brother, Simon, told John MacDonald that a no body, no parole law is needed, and offenders should only get parole if they co-operate with police. 

He says given the magnitude of the crime, concealment of a body is enough to warrant such a law being introduced. 

All Australian states have no body, no parole laws, with New South Wales the last to introduce it, in 2022.
