To do so, Peters opted for the personal touch, hosting Bishop at his own home in St Mary's Bay and getting Ardern to pop in to break the ice.
Bishop was effusive about the hospitality shown to her, saying the choice of his own home showed the closeness of the relationship.
The informal setting appeared to be the perfect setting for a rapprochement between Ardern and Bishop.
Bishop said the "delightful" conversation ranged in the "informal and welcoming environment."
There was even a hint baby talk or gossip (gasp) was involved, or as Bishop put it "matters of contemporary interest."
"As two female politicians we discussed a lot of matters of contemporary interest. We also discussed some very serious issues involving Australia and New Zealand."
It soon transpired Ardern's shoes were among the matters of contemporary interest.
Bishop is renowned for her interest in fashion - as is Ardern who chooses to showcase New Zealand designers as much as possible.
In a photo tweeted by Bishop, Ardern was wearing a pair of Allbird loafers which even Ardern admits look like slippers. They looked even more so next to Bishop's snappy stilettos.
Bishop's initial answer to a question about the shoes brought a slight death stare and a 'seriously?'
Then she answered that they had discussed the footwear and Ardern had explained she was dressed casually because she had come from a conference for Young Labour activists.
She understood the shoes were New Zealand made "and labelled the comfiest shoes in the world."
"So I had shoe envy at that stage."
Of the very serious issues, Bishop repeated her belief Hipkins' actions were unacceptable and inappropriate, but Ardern had acknowledged that.
"Of course, we move on. We see New Zealand as our essential partner, our natural partner. That will continue. In fact, today I think we deepened the relationship even further."
As for Peters, he did not cook. "I think Mrs Bishop deserves better than that."
