De Moor, who now works at Eastside Tattoo in Howick, is due to appear in the North Shore District Court next week.
Police spokesman Ross Henderson said staff were required to surrender all police uniform and equipment when they went on leave for more than a year, resigned or retired, or if they were suspended or removed.
In an unrelated case, a man has been charged with wearing police overalls while loading up goods to steal from a couple of big hardware stores. Clifton Murray O'Rourke, 48, is charged with stealing outdoor furniture and hand tools worth $782.98 from Bunnings Warehouse. He also allegedly stole a $1200 home theatre system from a Noel Leeming store on October 14. Noel Leeming operations manager Garth Brown said a man had entered the store dressed in police overalls.
However, O'Rourke said it was not him. "It's police persecution of the worst kind," he said.
O'Rourke is charged with possessing police overalls, leading people to believe he was a police employee. He is also charged with receiving a stolen trailer worth $4500 on October 18. Other items he also allegedly received included an Apple iMac worth $1646, hand tools worth $1100, bathroom accessories worth $13,000, nine buckets of paint worth $900 and whiteware appliances worth $1800. He is due in the Auckland District Court on November 26.
Official figures show two women and 32 men have been convicted of impersonating police from 2008 to 2011.
The majority of people were convicted in Invercargill, Waitakere, Counties Manukau and Christchurch. The most common age of offender was 17-19 or 25-29.
An impersonating charge against former North Shore policewoman Karis Charnley was dismissed last week, but her co-accused, Cameron Ross, was jailed on the same charge.
