No Duff is a volunteer Veterans NGO committed to providing immediate welfare assistance to past and present members of the NZDF, particularly Veterans, in order to ensure that the mental, physical, financial, spiritual and social health of all personnel is maintained at the highest possible level.

No Duff was formed in February 2016 by a group of former and serving NZDF Veterans in the aftermath of an incident where one of their mates very nearly became yet another statistic.

No Duff is run by an HQ section of nine former Royal New Zealand Infantry Regiment JNCO/SNCO Veterans currently headed by Aaron Wood.
