After seeing something similar elsewhere I decided to give this a go.
Honestly, I thought the top 1% (population the size of Hastings) might reach down to Whangarei or at most upper-upper Auckland, but it's the visual representation of the top 10% - basically everything north of about Kaikoura - that shocked me the most!
if you destroy or weaken the unions the rest just fall in place.
But you forget one important thing. The people who vote for this. People who support this. The people who want this to happen so bad they show up at the polls and vote for parties which make it happen.
None of it could happen without popular support of the willing and the apathy of the rest.
