Statistics NZ has amazing open data, and have offered to make some of it machine-readable via API for GovHack. But we have to tell them what we want! Post ideas here. www.stats.govt.nz
If it's ongoing, all the data that gets quarterly updates would be most useful in an API (national accounts, CPI, retail trade, etc).
If just for GovHack then maybe the Census mesh block dataset, digital boundary files, and business demographics data?
I've communicated this on to Stats NZ and am meeting them next week to discuss, thanks for the steer Aaron!
Comparable cost of living data across regions and cities in New Zealand.
This could be a cool thing to produce out of GovHack. What would it need as components?
