A former military intelligence officer who was convicted of stealing military equipment is back before the courts.

Former corporal Richard Keith Graham was sentenced to a curfew and supervision back in November 2018.

On Monday, he was charged under the Summary Offences Act 1981 for allegedly intending to frighten or intimidate a person by loitering near her house.

Graham appeared at the North Shore District Court on Monday and was remanded on bail to appear on April 28.

His occupation on the court charging document seen by Stuff, states he is an "airman".

A spokeswoman for the New Zealand Defence Force said Graham is no longer employed by the Air Force.

Mystery surrounded Graham's previous role with the Air Force but court documents show he spent three years in a sensitive intelligence role which carried a high level of risk and included being deployed overseas.

Graham had security clearance and was able to enter a store room at Auckland's Whenuapai airbase that housed what was described as "operationally sensitive equipment".

He also stole tools from a construction site at the base. In total, the goods had a value of $200,000.

Graham also admitted charges of supplying methamphetamine and the Class C drug BZP. He was also found with a psychoactive substance and having intent to supply it.

Initially Graham walked from court after being discharged without conviction, meaning the charges were not added to his criminal record.

But the Crown appealed to the High Court in Auckland, where Justice Hinton ruled the District Court judge had erred in law when she determined the consequences of Graham's offending outweighed the seriousness of the crimes.
