Hunt was jointly charged with two male teenagers, aged 16 and 17, with two charges of aggravated robbery.
He was also jointly charged with preparing to commit a crime in a public place at BP Havelock North, a summary offence which carries a maximum penalty of $2000.
Hunt, a fruit picker, was remanded on bail without plea for legal aid and will next appear on May 22.
The two male teenagers jointly charged after the incident appeared on Saturday and were both remanded on bail without plea to reappear in May.
Their arrests came after police executed a search warrant in Havelock North last Friday.
Police inquiries established the alleged offenders were in a Subaru station wagon which was allegedly stolen shortly before the robbery from Lipscombe Crescent, Havelock North.
Police said it was possible they canvassed a number of other stores in Havelock North before the aggravated robbery.
At the time of the third arrest police also recovered the stolen dark green Subaru station wagon, after earlier requesting information or sightings from the public.
Police have said there are now no offenders outstanding in relation to this incident.
The maximum penalty for aggravated robbery is 14 years' imprisonment.
