Police in Wellington are appealing to those who knew a man found dead at his home to come forward with any information about his movements.
Richard Wallace, 70, was found dead in his Strathmore Park home on Thursday, 22 July last week.
Police are seeking to establish his movements in the week prior to his death.
"Mr Wallace did have injuries and we are working to understand when and how these occurred," Detective Inspector Darrell Harpur said in a statement.
"Because of this, his death is still being treated as unexplained at this time.
"It is important we provide his family with answers and so we are asking those who knew him to provide us with details about his movements between Monday 19 July and Thursday 22 July."
The police investigation team has determined Wallace travelled with another person to the Strathmore Park and Miramar shops on Monday evening before returning home sometime after 7pm when he then entertained friends.
"If you visited Mr Wallace that Monday evening, or in the day's after, we are very keen to talk with you," Detective Inspector Harpur said.
Anyone with information can contact the team via 105 and quote file number 210722/6922.
Information can also be provided anonymously via Crime Stoppers on 0800 555 111.
