actually, the opposite happened. In the Prime Ministers statement

"While we do not have any reason to believe at this stage that there are any other suspects, we are not assuming that at this stage."

Other media reports said "Ardern said the investigation was ongoing but authorities believed there was only “one primary perpetrator.”

Video was posted on Twitter showing two gunmen. https://twitter.com/sotiridi/status/1106389979092135936

I haven't seen any reports that can vouch for the validity of that video.

But what is most strange is that in the live video he streamed, there was another guy in the car with him. So how on earth can the police and the PM state there was only "one primary peretrator". Very strange.
