Judge David Saunders asked for the reports to be completed by the man's next appearance on January 13.
The judge said he was "acutely aware of the public interest" in the case but ruled that interim suppression orders continue until then.
Judge Saunders told the man in the dock: "Your counsel needs to know a lot more about the case and the court needs to have medical information about you."
Applications by media to film in the court were rejected by Judge Saunders. He said police inquiries were continuing and revealing the man's identity at this stage could prejudice a fair trial.
Police investigating Hayden's disappearance recovered human remains from a crime scene at Ruru Lawn Cemetery in Linwood last week.
The remains were formally identified as his earlier this week.
His family said in a statement issued through the police: "Hayden was a shy, sensitive and vulnerable boy who, like many young teenagers, was struggling to find his way in the world. As a family we loved him very much and we were committed to helping him transition through this difficult period in his life."
Two other people charged in relation to Hayden's disappearance also appeared in court today, across town at a district court session at Nga Hau e Wha marae.
An 18-year-old woman accused of being an accessory after the fact was remanded without plea on bail until February 9. Her name continues to be suppressed.
A 35-year-old Christchurch man, who was previously identified, was granted name suppression today by Judge Brian Callaghan.
He is charged with robbing Hayden of a cask of wine on August 22 and now police allege he also stole a cellphone and iPod from the teenager on the same day.
His lawyer Tony Garrett argued that his name was being tainted when it was published alongside the murder charge.
