Defence bosses were asked to allow soldiers in Afghanistan to ignore the Geneva Convention so medics could use heavy weapons.
The request was made in the 2010 review into the death of Lieutenant Tim O'Donnell, which described Kiwi patrols in Afghanistan to be "minimally manned".
Defence Force chief Lieutenant General Rhys Jones has told the Herald a formal review into the idea was carried out by legal staff at NZ Defence Force headquarters.
He refused to release it but said the current policy retained the role of medics as non-combatants who carried light personal weapons in non-combatant roles.
The statement contrasted with the finding in the July 2011 military review into the death of Lieutenant O'Donnell, which stated medics would be trained in the use of heavier weapons before being sent to Afghanistan. It said medics would be trained in the use of "support weapons" - which usually include heavy machineguns, grenade launchers, mortars and rockets.
