Official Information Act Request
Dear Carol
Thank you for Official Information Act 1982 (OIA) request dated 1 May 2022 in which you
requested:
I request a complete copy of the 'NZ Police Telecommunication Investigations
Manual'. For any parts of the document that you choose to censor out, I request an
annotation detailing under which section of the Official Information Act you are
withholding that information.
I have attached a redacted copy of the Police Telecommunications Investigation Manual.
You are advised that all redactions within the copy of this attached manual have been made
pursuant to section 6(c) of the OIA, as the making available of the information would be likely
to prejudice the maintenance of the law.
You have the right to ask the Ombudsman to review my decision if you are not satisfied with
the response to your request. Information about how to make a complaint is available at:
www.ombudsman.parliament.nz.
Yours sincerely
David Lankshear
Detective Senior Sergeant
