When do we see the secret addendum?

NBR reported:

Meanwhile, Mr Peters revealed there is a 38-page addendum to the coalition agreements that have already been publicly released. It will be released later, he said.

The document was a briefing to government ministers, laying out specific rules and processes over how they should address issues like accountability and media strategy while working as a cohesive government.

I’m amazed that the media haven’t reported on the existence of this secret addendum and demanded it be immediately published.
