Time - sooner rather than later, probably - is going to tell us how big a mistake.
Debate will continue, and the plan may change, but at least now the Pakeha-Maori rift is healing.
Yesterday's announcement wasn't just about setting the blueprint for changes.
It also exhibited some of the lack of depth of cultural understanding that led to the recent problems, when Craggy Range winery director Mary-Jeanne Hutchinson beckoned Ngāti Kahungunu chair Ngahiwi Tomoana to "do the nose thing".
The "nose thing' of course, is the hongi, and the lead-up to today, and the ensuing journey will provide Hutchinson with plenty of opportunity to learn more about Maori culture.
Local government have some "learnings" here as well. Just because you can legally do something, doesn't mean it's always the right thing to do.
