Alan Jones has hit back at Coles after the supermarket pulled adverts from his 2GB radio show.

Jones came under heavy fire in August after saying Scott Morrison should 'shove a sock' down New Zealand Prime Minister Jacinda Ardern's throat.

The radio presenter apologised for the comments but businesses including Coles cut ties with his show.

One of Jones' listeners wrote to Coles to complain about the decision.

He received a reply saying Coles 'valued diversity, respect and actively promotes the rights of team members and customers'.

On Thursday morning, Jones criticised that response and labelled the supermarket 'corporate hypocrites,' adding 'it's time I entered the ring'.

He accused Coles of 'ripping off dairy farmers' with low milk prices and said the company 'wants to occupy the high moral ground.'

'Is this the same mob who have been ripping off dairy farmers by screwing down the processor who then screwed down dairy farmers on the farm gate price. Is this the same Coles?' Jones asked.

Calling for a boycott, he urged listeners to give Coles a 'very wide berth'.

'I will bet you if my listeners had a choice between the value systems I practice on many fronts and especially in relation to dairy farmers they would choose me everyday ahead of Cody at Coles customer care,' he added.

Jones finished his tirade with an ominous warning to the supermarket.

'My advice to Coles is to get your own value system in order before passing judgment about other people but don't worry we can both play the same game,' he said.

'And good luck to you by the time I'm finished.'

Daily Mail Australia has contacted Coles for comment.

Koala Mattress, Bing Lee, Anytime Fitness and Volkswagon were just a few of the brands to join the boycott thought to cost 2GB up to $1million.

Following the snub, 2GB extended its ad breaks to make up for the loss in revenue.

Mr Jones made the contentious remark when discussing Ms Ardern's views on climate change.

'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.'

Jones wrote an apology letter to Ms Ardern, saying he never wished her 'any harm'.

'My dear Prime Minister,' the letter read.

'One of my comments which has been broadly reported, and doesn't need to be repeated here, didn't come out quite as I intended.

'I meant to say 'put a sock in it' and my actual words were taken literally by some who took offence on your behalf.'

Jones continued to say he hadn't ever intended to offend the Prime Minister.

'I would like to assure you that I did not intend to suggest any violence towards you.'

'I would never wish any harm to you.

'Please accept my sincere apology for the words spoken, and I hope that my intentions, are at least now, clear.'

Despite the controversy, Jones' breakfast show on 2GB managed to maintain the market leading share in Sydney with 16.8 per cent, despite a modest dip of 0.3 of a percentage point in September.

The closest a rival radio presenter got to the embattled broadcaster was KIIS FM duo Kyle and Jackie O who drew in an 11.6 per cent share of the market.
