Collins told Peters he was wrong. But Peters persisted, accusing Collins of "a corrupt abuse of her Cabinet position".
That was too much for Collins. If Peters was worrying about corruption, she said he should consider "a member of Parliament who asks questions in this House and written questions to help his girlfriend in her position with a major global company".
Collins was referring to Peters' partner, Jan Trotman, who was NZ boss of a division of Johnson & Johnson. Peters demanded an apology.
He got a grudging withdrawal.
Later in question time, Collins rounded on Labour's Grant Robertson. He argued Collins was giving the impression that she went to China "to work for her husband's company and behaving in a corrupt manner".
Retorted Collins: "The only person drawing that sort of inference is a person with a mind like that member."
It was not one of her more devastating put-downs. But you got the drift.
