I just found an interesting article that explains how the accused got the gun, and it's probably not what you expect.
“The person police believe killed McKinnon can now be named as Mark Garson.”
Roderick Finlayson supplied the gun used to shoot Sean McKinnon and was sentenced to six months community detention by Justice Lang after earlier pleading guilty to unlawful possession of a firearm and ammunition.
Finlayson told the court he bought the gun in August 2019 but had no knowledge of what the firearm would allegedly be used for. According to the summary of facts read to the court during his sentencing, Garson allegedly contacted Finlayson, who has a firearms licence, via Facebook in
March of last year asking for him to purchase a firearm.
During the exchange that continued sporadically in the following months, Finlayson suggested purchasing a gun on TradeMe and he would pick it up. He said he had “so much to lose” by buying the gun.
On
August 12, 2019 the pair agreed that Finlayson would buy the firearm in exchange for $400. Garson allegedly told Finlayson the type of firearm and ammunition he wanted specifying “strong deadly ammo” to use for hunting at the back of the farm.
The following day, Garson allegedly picked up Finlayson and they drove to a gun store where Finlayson purchased a 12G Dickinson XX3 shotgun with three different types of ammunition, showing his firearms licence to the store owner as proof before being dropped home.
Read the article as to how the sentence was arrived at.
You don’t usually see how a sentence is arrived at in such detail but that’s because it’s usually the sentence for the murderer which is more straight forward.

I read in another article that Finlayson originally told police he stored the gun and bullets in a gun safe. However, more recently he admitted giving the weapon to Garson that same day.
NB: Community detention is a punitive sentence that restricts an offender's movements during their curfew. It requires an offender to remain at an approved residence at certain times specified by the court. This is known as the offender's curfew.
