UMR has just released a poll [PDF link] measuring support for a supercity.
Stuff reports on it under the headline “Voters back Auckland supercity”:
Though the poll’s sample of just 483 is small, it is the first real indicator of support for the supercity concept, with 45 percent of Aucklanders in favour, and 43 percent against.
Yet the report itself indicates that the margin of error is +/- 4.7% and states very clearly that its key finding is that:
The level of support amongst Aucklanders for a super city is roughly the same as the level of opposition.
So, no, Stuff, Aucklanders do not back a supercity (and I bet they don’t back being denied a chance to have a say on whether or not one’s forced on them either).
