Australian right-wing extremist Brenton Tarrant opened fire at dozens of Muslims at two Christchurch mosques during the Friday prayers on March 15.
The act of remembrance was organised to mark one week since a suspected far-right terrorist killed 50 people in shootings at two mosques, streamed live on Facebook.
Although a Royal Commission of Inquiry was on the table, Ardern was not able to confirm at the time if that was the route the Government would take.
"It's handsome to see what the community has put together to show they care about us, and to show that we are all one", said Boztas.
The agencies taking part in the inquiry would include the New Zealand Security Intelligence Service, the Government Communications Security Bureau, police along with Customs and Immigration.

Following the attacks, Ms Ardern announced that there would be a ban on all types of semi-automatic weapons, adding that the new legislation would be in place by 11 April.
