If either of the options - taking out the status quo possibility - is recommended and becomes the new path we take, it will certainly be the biggest change in local government terms in at least 25 years.
In 1989, the council structure in Wairarapa underwent the biggest upheaval in decades when Sir Brian Elwood decreed the old borough and county council structure was to fall victim to change.
That led to the creation of the district councils - Masterton, Carterton, Tararua and South Wairarapa - and to much mumbling and grumbling among many in the community that the demise of the small town borough and rural councils would spell doom.
Fair to say I think we have long since settled into the 1989 models and, by and large, things have worked out okay, although increasing rates are always a source of discontent.
But then again they always were, even when small towns took care of themselves.
Should the commission's recommendation be in favour of a unitary authority - and that comes to pass - a new round of adjustments will be needed and any remaining vestige of parochialism will need to be killed off. If the proposal favours joining forces with Wellington, then even wider reaching adjustments could be necessary so, all in all, we are in for interesting times.
