NZ electorate map finalised

0

In the lead-up to the New Zealand election in September, the final map of electoral boundaries was released last Thursday. The changes are relatively minor in most seats, although a large number of electorates saw some change in comparison to the draft boundaries.

Back in October I posted an extensive analysis of the draft boundaries. I won’t repeat all of the same analysis, but I have updated the data to reflect the final version.

You can downloaded the following updated files:

And following the fold I have posted my estimated margins of the new electorates.
