Six months after a member of the Diplomatic Protection Service left a loaded handgun in a bathroom at Parliament, police say their investigation is still continuing.
The officer, who was protecting former Prime Minister John Key, left a Glock pistol behind in a bathroom in June, where it was found by a civilian.
At the time, Mr Key described the officer as utterly professional and said they had made an awful mistake.
Police told RNZ their investigation was still ongoing, and they could provide no further information at this stage.
They would not say whether the officer was continuing to work, or whether he had been stood down.
