Gustav Otto Sanft from Māngere, south Auckland, is serving a sentence of four years and 10 months for manslaughter over the death of his daughter, Amokura Daniels-Sanft, in 2016.
Sanft was also convicted for unlawful possession of a rifle and cannabis supply.
Sanft's defence argued he never intended to kill his daughter, but pulled the trigger of the shotgun, possibly not knowing the firearm was loaded, to scare her when she was "playing up".
Sanft has a statutory release date of April 30, 2022.
