She's co-hosting the summit in Paris this week with French President Emmanuel Macron, where it's expected countries and companies will pledge to regulate social media, in the wake of the Christchurch attack Facebook livestream.
In a statement on Wednesday, Facebook vice president of integrity Guy Rosen following the "horrific" terrorist attacks in New Zealand, it had been reviewing what could be done to limit services spreading hate.
"Today [Wednesday] we are tightening the rules that apply specifically to live," Rosen said.
"We will now apply a 'one strike' policy to live in connection with a broader range of offenses.
"From now on, anyone who violates our most serious policies will be restricted from using live for set periods of time - for example 30 days - starting on their first offense."
Facebook did not specify which offences were eligible for the one-strike policy or how long suspensions would last, but a spokeswoman said it would not have been possible for the alleged gunman to use live on his account under the new rules.
Rosen said it planned on extended restrictions in the coming weeks, beginning with preventing people creating ads on Facebook.
"Our goal is to minimise risk on live while enabling people to use live in a positive way every day."
On Tuesday, Ardern wouldn't rule out changing laws that could go as far as blocking Facebook if it's used to share extremist or violent content like the alleged Christchurch gunman's video of the March 15 terror attack.
"Certainly at this stage [we're] learning from what we see internationally."
