Over the course of the past two years, their trajectories have been quite different.
Ardern is charismatic, she smiles a lot, she nods a lot, she says inspirational things and you want to believe her.
But slowly it's being undone. The Empress has no clothes. She lacks commercial and interpersonal acumen. She is not a natural leader, she's indecisive and farms things out too much _ reports, reviews, committees, working groups.
On the big issues she sits on the fence. Even on the small ones she says she will "take advice".
What's worse is that this week it seems to me that she lacks genuine empathy. She runs a seemingly inept inner circle – her office is shambolic.
She's no CEO but she would make a great Head of Marketing and Communications – a lot of talk – a lot of PR, no substance.
Not transformational, not open honest and transparent, not decisive, not even aware of what's going on within her own party.
On the other hand, we have Simon Bridges.
Backed into a corner by conspirators sharpening their knives and people taking odds on his demise, he's had to claw and dig his way into the fight. Today he's looking more comfortable, self assured, and actually self effacing in respect to his weaknesses.
Yes he knows he will never grace the cover of Vogue and yes he talks with a fierce Kiwi twang, but he's getting clearer on what leadership looks like.
And that's the difference.
Brought to the table with so much fanfare and goodwill, Ardern has proceeded to do not a lot more than work the international stage, appoint working groups and let others decide things.
She's "listening" she keeps telling us. Well that's all well and good but sometimes a leader has to act.
Leadership is not always about taking a back seat and letting the committee, the QC, the consultants decide.
So what have we got as of now? Party president Nigel Haworth's resignation– which was always going to be the outcome - and the Prime Minister apologising.
What we need to see is momentum in terms of leadership and decisive action.
The QC's report is going to take a month. Is this all a bit too little, too late?
