Police are waiting for results from postmortem tests in the hope they will explain how an Oamaru man died on Saturday.
Wayne Ross (46) was found dead in a block of shops on the corner of Arun and Hull Sts about 5pm by Oamaru police after family had expressed concern.
Initially, a police team of 15 were involved in an unexplained death investigation and a postmortem was carried out on Tuesday. Police said they were now waiting for a toxicology report and the death remained unexplained.
A smaller team was still continuing investigations and would welcome any information about Mr Ross' movements after he left a Towey St address at 7pm on Friday.
He was 178cm tall and of medium build.
He was wearing blue jeans and a two-tone blue chequered jacket with a woolskin lining and collar.
Anyone with information can contact Oamaru police on (03) 433-1400 or, anonymously, Crimestoppers (0800 555-111).
