Tony Waldron was found dead in his bed at his home in Gardiners Rd on September 18 this year.
Detective Senior Sergeant Richard Quested said today a 26-year-old Christchurch man would appear in the district court today.
Inquiries were still ongoing.
“The investigation into Tony’s death is far from over and there is still a lot of work for us to do," Det Snr Sgt Quested said.
"Our thoughts are very much with the Waldron family at this time and we are committed to providing them with the answers to Tony’s death.”
Last week, a search warrant was executed at a property in Hoani St, Papanui, in relation to Mr Waldron's death, while earlier this week the Selwyn riverbed was scoured by police.
