The death of a man who was found near the Heathcote River in Christchurch on Friday is not being considered suspicious by police.
A post examination of Woolston man Jeff de Moulin, 41, was performed yesterday afternoon.
Detective senior sergeant Brian Archer said preliminary findings did not indicate any suspicious circumstances.
A man Mr de Moulin and his partner were drinking with on Thursday night had also been interviewed by police.
"As a result of these enquiries we are now satisfied that there is no indication of any suspicious circumstances surrounding Mr de Moulin's death," Mr Archer said.
