White supremacist Philip Arps has had a second appeal against his sentence dismissed.
The Christchurch businessman sent the video footage of the mosque shootings to 30 associates and asked for it to be modified with crosshairs and a kill count.
He was sentenced to 21 months in prison in June.
A Court of Appeal judgement released on Thursday found the court did not make a mistake in its assessment of Arps' views.
Arps argued the punishment was excessive and he should have received home detention.
The High Court dismissed his first appeal in August, saying home detention would have been inappropriate.
Fifty-one people lost their lives in the attack on two mosques, which was live streamed on Facebook.
At Arps' sentencing in June, Judge Stephen O'Driscoll told the Christchurch District Court that distributing the video the day after the attack demonstrated "particular cruelty and callousness".
"I don't see any indication of remorse on your part," Judge O'Driscoll said.
He said the prospect of rehabilitation or Arps changing his views on religion or race was virtually non-existent.
