The mass shooting of 49 people at mosques in Christchurch is not only exponentially larger than the Aramoana shooting in 1990, but it also equates to the same number of gun homicides that happened in the country from 2010 to 2016, according to New Zealand police data.
Ardern descrived the killings as "one of New Zealand's darkest days".
In spite of this, a cult of personality has grown around Kjellberg, as evidenced by the "subscribe to Pewdiepie" meme evoked by the gunman, in which fans encourage people to subscribe to Kjellberg's channel so that he remains the most-followed person on YouTube.
Shots were fired at the first site, the Al Noor Mosque, just after 1:30 p.m. Friday, right when worshippers would be gathered for afternoon service.
Footage of the attack on one of the mosques was broadcast live on Facebook, and a "manifesto" was also posted online that denounced immigrants as "invaders". "The horrific active shooter scenario at a mosque is something we all pray never happens (but) there is no active intelligence that there is any immediate threat in the U.S. But we can not be complacent".
In the video, the killer spends more than two minutes inside the mosque spraying terrified worshippers with gunfire.
He said he and others escaped by breaking through a glass door.

A now-deleted Twitter account that is believed to be linked to the accused shooter shows what appears to be three assault-rifle magazines, one of which has Bissonnette's name on it.
Separate "endorsements" are required to own semi-automatic weapons like those used in Friday's attack, as well as pistols and other restricted weapons.
He said he was a 28-year-old white Australian and a racist.
The gunman's manifesto was a welter of often politically contradictory views, touching on numerous most combustible issues of the day, among them the Second Amendment right to own guns, Muslim immigration, terrorist attacks and the wealthiest 1 per cent.
From what we know, it does appear to have been well planned.
Christchurch is home to almost 400,000 people and is sometimes called the Garden City.
"I want to reassure all New Zealanders that we are doing absolutely everything in our power to respond to this attack, and deploying all available resources in communities across New Zealand", Bush said.
