ASB Bank, one of the country's biggest banks and a unit of Commonwealth Bank of Australia, is in talks on whether to pull its ads from social media, a spokesman said.
"Businesses are already asking if they wish to be associated with social media platforms unable or unwilling to take responsibility for content on those sites," the two groups said in a joint statement. Media representatives from Facebook and Alphabet Inc's Google did not immediately respond to emails seeking comment.
Both Facebook and Alphabet Inc's Youtube said they are also using automated tools to identify violent content and remove them.
