Police have opened an investigation into the use of its intelligence database to access documentation in relation to the death of police officer Lyn Fleming.
The use of the National Intelligence Application was governed by strict rules.
Police said the rules were in place to “protect privacy” and “prevent the disclosure of sensitive information”.
“A process is now underway to determine the rationale for and legitimacy of each of those checks.
“Unauthorised use of NIA will not be tolerated and final decisions on any sanctions for staff will be decided by a dedicated team.”
Last week, Fleming was farewelled in Nelson by family and colleagues. She died after being struck by a vehicle in the early hours of New Year’s Day.
A large number of people attended the funeral of the 38-year police veteran at the Trafalgar Centre.
Fleming was the 34th officer to die in the line of duty in New Zealand, the first female officer and the only officer from the Nelson region to be killed.
A 32-year-old man has been charged with murdering Fleming and attempting to murder Senior Sergeant Adam Ramsay.
