A man accused of a road rage assault has been assessed as fit to stand trial by two health assessors and has denied all the charges he faces.

Fifty-one-year-old Andrew George McDaniel, a Swannanoa property developer, entered the pleas at an appearance in the Christchurch District Court before Judge Brian Callaghan today.

Defence counsel Michael Starling said he was unable to challenge the findings of the psychiatric and psychological reports, and asked for McDaniel to be remanded to a case review hearing.

McDaniel has not consented to the continuing remand in custody to Hillmorton Hospital where he is held for compulsory assessment under the Mental Health Act.

Judge Callaghan remanded him in custody to August 10 for a case review hearing, which is the next step on the way to trial.

McDaniel denied charges of injuring a man with intent to cause grievous bodily harm and wilful ill-treatment of a dog.

Police alleged that McDaniel had 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, on March 23. The group included children aged 6 and 9 and a puppy.

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

McDaniel also denies charges of assault, driving with excess breath-alcohol, and careless driving from an incident in November 2014.
