A Canterbury man who allegedly assaulted a three-month old baby has pleaded not guilty to all charges.

The 35-year-old was granted continued name suppression when he appeared in Christchurch District Court this morning.

Police allege in November last year the man assaulted the 14-week old child and caused grievous bodily harm.

He also faces charges of assaulting a woman and breaching a protection order.

The man was remanded on continued bail until his next appearance in December.
