At least three more companies have withdrawn advertising from Alan Jones' morning show as the fallout from his comments towards New Zealand Prime Minister Jacinda Ardern last week continues.

Mattress brand Koala, global gym franchise Anytime Fitness and hardware retailer Total Tools on Monday joined Snooze in pulling advertising altogether from 2GB radio station as a result of Jones' comment that Australian Prime Minister Scott Morrison should "shove a sock down [Ms Ardern's] throat".

ME Bank withdrew advertising from Jones' show on Friday and a spokesman said it was reviewing its position over ongoing expenditure.

Jones' comment, made during last Thursday's breakfast program in response to Ms Ardern's criticism of Australia on climate change at the Pacific Islands Forum, drew widespread condemnation – including from Mr Morrison who described it as "way out of line".
