The Chief Ombudsman has found the New Zealand Defence Force was justified in withholding most of the information requested in relation to Operation Burnham.
However, Chief Ombudsman Peter Boshier has ordered the NZDF to release four more briefing papers in relation to the operation in Afghanistan in 2010, and information about the identities of insurgents killed.
He also said the NZDF could have been "more responsive" in releasing information.
After the book Hit and Run was published in March 2017, by investigative journalists Nicky Hager and Jon Stephenson, a number of people requested further information from the NZDF on Operation Burnham through the Official Information Act (OIA).
NZDF withheld much of the requested information, arguing its release would likely prejudice the security and defence of New Zealand, or the future entrusting of information to New Zealand.
