The death of Paeroa pizza and pasta shop owner Jordan Voudouris is now being treated as a homicide, police say.
A post-mortem examination was carried out in Auckland today as the probe into the death of the popular 55-year-old continued.
Mr Voudouris was found dead on a driveway behind Mykonos Pizza and Pasta Paeroa yesterday.
Detective Senior Glenn Tinsley said the post-mortem examination proved the death was suspicious.
"I can now confirm we are dealing with a homicide investigation which means the earlier approach of treating the unexplained death as suspicious was the correct one.''
