Former Ministers have addressed "trauma and humiliation" as well as the "pain and relief" of being an MP during their valedictory speeches in Parliament last night.
One revealed that they had even contemplated suicide due to the intense pressure of being an MP, and subsequent media criticism.
A number of MPs bowed out of Parliament, giving their final address to the House last night.
"I am sorry for the hurt and humiliation I have inflicted on my family and for the direct impact my actions have had on so many others," he told the House.
He admitted that the relationship with the former staffer was not appropriate, and acknowledged the power imbalance involved.
Lees-Galloway spoke of the "dehumanising trauma" that he, and his family, experienced after he said they were used for "headlines and clickbait".
But he said his family were "tough cookies … We will come out of this stronger, together." When he looked back at his life, it would be divided into two periods – before 2020, and after 2020.
He said it had been a rough year: "There was the near-end of our marriage, the death of my father and now the end of my political career. We even had to put the dog to sleep a few weeks ago."
Lees-Galloway praised Ardern and spoke highly of the Government's record and some of his achievements, such as extending paid parental leave.
But he spoke of some of the difficulties he had with Labour's coalition partner, New Zealand First.
"If stakeholder relationships can be hard to manage, they've got nothing on coalition relationships."
In fact, he said that at the beginning of the term, he would never have guessed he would be the Immigration Minister who closed New Zealand's borders.
"I mean, I knew we were in coalition with NZ First, but it still never crossed my mind."
She said her time as an MP was a privilege but at times she was made "public spectacle". "I've recently called out the behaviour in our Parliament and described our political culture as toxic.
"For our political system is sick and we all know it."
Curran revealed that there was a point when she had "counted the number of sleeping pills I had".
"Thankfully, I sought help instead."
She was critical of the media in her speech, saying it was focused on conflict, perceived or real slip-ups rather than substance and the quality of ideas.
"Politicians should be held accountable. But we are not prey. The accountability lacks perspective. If you don't believe me, go ask the public.
