Jones, 78, has regularly targeted the Kiwi leader on his breakfast radio program, labelling her, amongst other things, an "utter lightweight" and a "clown".

He crossed a line in August when he invoked violence against Ardern, saying Australian Prime Minister Scott Morrison should "shove a sock down her throat" over her views on climate change.

After criticism including a sponsor backlash, Jones apologised to Ardern, who refused to get drawn into the debate.

"I don't have an opinion about every single person that says something about me," she said at the time.

However, a Tweet from 2012 - unearthed by Sky News - shows Ardern did have a view on Jones.

"I know an Alan Jones. Unlike the Aussie version, he isn't a git or intensely disliked by the population," she wrote.

Reminded of the remarks on Tuesday, Ardern chose again not to buy in.

"This is a reference to a tweet from seven years ago," she said.

"Of late you've seen I've not been offering up thoughts or opinions on the issue of Alan Jones. I don't intend to now."

Ardern's assessment - made when she was an opposition spokesperson and five years before she became prime minister - came the day after Jones' most infamous gaffe was made public.

Jones, speaking to a Liberal party fundraiser, labelled then-Australian prime minister Julia Gillard a "liar" and said her father John had "died of shame" because of that.

The 2GB broadcaster was flooded with complaints, losing further advertisers, before publicly apologising.

Jones' track record of harmful language against female leaders has seen him condemned by the past five Australian prime ministers at least.

In August, after his latest Ardern outburst, Jones was labelled an "appalling misogynist" by Malcolm Turnbull, who said "his pattern of using abusive and violent language against women, particularly women politicians, is disgraceful."
