A violent North Canterbury road rage incident is heading towards a hearing on whether the 51-year-old charged will be able to stand trial.

The Christchurch District Court has had one psychiatric report prepared already on Andrew George McDaniel, and a second report was ordered today by Judge Gary MacAskill.

McDaniel, a Swannanoa property developer, was remanded to a forensic psychiatry unit under the Criminal Procedures (Mentally Impaired Persons) Act for the new report to be prepared.

He is due back in court on June 24 when a date for a psychiatric hearing may be set.

Judge MacAskill said: "An issue has arisen as to whether he is fit to plead."

Judge MacAskill considered the briefs of evidence today but no witnesses were called at the hearing. Defence counsel Michael Starling said McDaniel did not consent to the remand, but was not calling evidence or making submissions to oppose it.

McDaniel faces charges of injuring a man with intent to cause grievous bodily harm and wilful illtreatment of a dog.

Police alleged at the time that he reacted after the father of a family out walking near the Eyre River, Eyreton, indicated that McDaniel was driving too fast as he went by in his four-wheel-drive vehicle. The group included children aged six and nine, and a puppy.

The police allege McDaniel then did a series of u-turns and passes in the vehicle during which the man was run over causing injuries to his ankle, back, and shoulder. The puppy was also run over and had to be euthanised because of its injuries.

McDaniel also faces charges of assault, driving with excess breath-alcohol, and careless driving from a November 2014 incident.
