Labour could be forgiven for having had a momentary sense of utu when Greens co-leader Metiria Turei was facing her own existential crisis yesterday after fresh revelations of dishonesty.
If Turei had not fashioned herself as victim of poverty that had demanded she commit benefit fraud, the Green Party would not have surged in the polls, Labour would not have plunged, there would have been no crisis in Labour and Andrew Little would still be leader.
That's why utu is only momentary.
Much as Andrew Little did the decent thing and resigned without a hint of self-pity, Labour did not realise how little it would miss him until he had gone.
Jacinda Ardern's transition to leader has melted those hardened Labour Party members who were appalled at yet another change of leader so close to an election.
The public acclaim is real. When Ardern boarded a plane with a television crew this week filming her first week in the job, the plane broke into applause. A similar thing happened to John Key after he first became Prime Minister.
She has gone from strength to strength and grabbed the opportunity to metaphorically club a few media cave-men over their stone-age views on working women and pregnancy. A sheer gift to her.
Ardern's deputy, Te Tai Tokerau MP Kelvin Davis, has also had an impressive week.
He is likely to not only extend Labour's appeal to Maori voters but to blue-collar blokes. He is down to earth, he is moderate, he has been a school principal and he has no problem confessing his love affair with the remote control and Sky Sports.
Ardern gave yet another command performance at a press conference yesterday spelling out with a combination of force and compassion - and not a hint of utu from her - that she could not have Turei in any cabinet of hers.
It was a case of the smiling assassin - sacking her first minister before she even had the chance to be a minister. It had echoes of both Helen Clark and John Key.
Ardern's elevation has been the cleanest transfer of power by any leader in recent memory, way surpassing that of Key to Bill English last year, in which he faced a couple of faux rivals.
Part of the reason for this transition is that it had no origins in a coup or scandal or undertones of a selfish decision, as Key's had.
Little's departure was in stark contrast with Turei's performance yesterday, which dripped with self-pity.
She professed to take responsibility for historic wrong-doing by saying she would not take a cabinet position.
