My location is Timaru.
The only locations in the South Island where Genius is available is CHCH & Dunedin.
Are you suggesting my wider area is CHCH?
Not at all, just offering a possible explanation. I went through and replicated your results, rather annoyingly you're right. Annoyingly in that Orcon provides us with details on where their services are offered, so that shouldn't happen (though Genius was added late in the project).
Apologies for that, especially because Genius does look like a cool plan, we'll get that fixed.
