Sure.
First of all, Governor General Sir Hardie Boys was the first Governor General to hold that post in New Zealand after they switched to the proportional representation voting. He took it upon himself to make some public addresses well ahead of time prior to being called upon to identify the government of New Zealand.
He set out the criteria that he would be using to identify a government, on the basis that he thought it would help things immeasurably if everyone was on the same foot and understood what was.... He believed it would help negotiations among the political parties if they knew what was going through his mind, so they wouldn't be operating in the dark.
Thereafter, he made periodic speeches about his office, explaining what its functions were. These were communications that weren't intended simply for the political actors, but also for the public, so that they would understand what it was he was doing as a form of providing for public accountability. Being very aware of the fact that he was exercising power and yet was not directly responsible to the electorate, that was the way in which he made himself accountable.
As far as the specifics of what he had to say are concerned, these were in some fairly wide-ranging speeches. I provided a link to the New Zealand Governor General's website in my written remarks that directs to where some of his speeches are archived.
