Koala Mattress, Anytime Fitness and Volkswagen are the latest brands to cut ties with Alan Jones' radio show after he suggested Prime Minister Scott Morrison should "shove a sock down" the throat of NZ Prime Minister Jacinda Ardern.
"Koala has cut ties with Alan Jones ... We're a significant buyer in the medium, and it's something we should have done earlier," the company posted on Twitter.
"Climate change is real, violence against women starts with words and the bloke has had too many chances ... @2GB873 time to wake up."
Anytime Fitness also withdrew its advertising spend from Macquarie Radio on Monday, joining the likes of ME Bank, Snooze, Bing Lee and Amart amid rising backlash over Mr Jones' remarks.
"The comments made last week by Alan Jones regarding Jacinda Arden do not represent our view or values," Anytime Fitness said in a Facebook post.
"For this reason, we pulled all our advertising from 2GB (Macquarie Radio) last Friday and do not have any further advertising planned with the station."
Responding on its Facebook page to people threatening to sell their cars or choose another make for their next, Volkswagen Australia said it had "ceased all advertisements with 2GB" from Monday.
Mr Jones criticised Ms Ardern last Thursday after she said "Australia has to answer to the Pacific" on climate change at a forum in Tuvalu.
"Here she is preaching on global warming and saying that we've got to do something about climate change," Mr Jones said on his program.
"I just wonder whether Scott Morrison is going to be fully briefed to shove a sock down her throat."
Mr Jones - who previously suggested former Prime Minister Julia Gillard should be put in a "chaff bag" and thrown out to sea - initially insisted his comments had been "wilfully misrepresented" before acknowledging he was in the wrong and saying he had apologised in writing to Ms Ardern.
Nine Entertainment last week said it wouldn't try to rein in Mr Jones and his fellow talkback shock jocks when it takes full ownership of Macquarie Radio.
But Macquarie Radio said on Sunday it was prepared tear up the star's multi-million contract if he repeated "commentary of this nature".
The company only re-signed Mr Jones on a lucrative two-year contract in May following months of tense negotiations.
