Having taken a firm position - or as firm as you can take when dealing with diplomatic immunity - McCully found as late as Tuesday night that the officials had pulled the rug from under him and the Prime Minister.
The questions might get answers after an independent review initiated by John Allen, the ministry's chief executive, has focused on how "informal communication" with the Malaysians left open the possibility of a different course of action to that expected by Key and McCully.
It is quite possible that the New Zealand officials put up their option of ensuring the diplomat was quietly returned to Malaysia - something which would have suited everyone bar the victim of the assault. Her right to justice has proved to be crucial in preventing the whole episode being swept under that aforesaid rug.
It has also brought the chain of responsibility for the mess into sharp focus - especially whether anyone should get the chop.
It is unlikely McCully offered Key his resignation. McCully can claim the old defence of being responsible, but not to blame. And, anyway, Key would never have accepted it. Allen did offer to step down, but was told likewise by McCully to stay on.
So the lowlier officials are in the gun. They always are when ministers try to distance themselves from the blunders of their public servants. But this time the officials are the ones with the questions to answer.
