The vice-president of the Otago gun club where the Christchurch terror attack accused trained has contacted police to hand in his now-illegal weapon.
Prime Minister Jacinda Ardern announced a ban on military style semi-automatic (MSSA) firearms and assault rifles on Thursday afternoon.
Bruce Rifle Club vice-president Scott Williams said he filled out an online form that evening, notifying police he wished to hand in a firearm.
He owned just one weapon affected by the law changes, but would not say what type of weapon it was on Friday.
Milton residents were left stunned after it was revealed the alleged mosque gunman was a member of the club where he practised shooting.
