A jeweller realised a robbery was taking place inside his shop after seeing a man helping himself from a display cabinet, a jury has heard.
Jackson Anderson, 25, is facing a charge of the aggravated robbery of Dargaville's Distinction Jewellers on May 16, 2011, two charges of unlawfully taking a motor vehicle and three of petrol thefts.
His trial started before a jury of six women and six men in Whangarei District Court yesterday.
More than $22,000 worth of jewellery, including gold, platinum and diamond rings were stolen in the heist.
Answering questions from Crown prosecutor David Stevens yesterday, Distinction Jewellers' owner Brian Burnett said he discovered the robbery after returning to his shop from the post office and bank on the morning of May 16, 2011.
