Brandon Joel Worthington was so desperate for cash to buy food for his partner's two children he carried out an aggravated robbery.
The 25-year-old went into the Onerahi Post Shop, pointed an imitation gun at a female worker and whispered his demand for her to hand over all the money.
The teller, on her first day of the job, handed over $1150. Minutes later Worthington bought food from a supermarket.
He appeared in the Whangarei District Court yesterday to plead guilty to aggravated robbery on September 9.
A police summary of facts revealed before Worthington went into the Post Shop he had taken a green plastic bag with a change of clothes and placed it near the public toilets on Waverley St about 2.20pm.
