How do I see local trends for my (unsupported?) location in Twitter?

Question

The options for 'local trends' on Twitter are very limited: I count 20 countries + world wide and 21 cities. Are there more 'official' local trend options or is that it?

Is there a planned timeframe for New Zealand (or other countries) to be added?

Answer 1

There is a small notice when you use the old Twitter.

Don't see your location? We're working on it

And from Support

If you don't see your country or city, it means we're not receiving enough tweets from that geographical area to create a quality list. Locations are not manually decided, but displayed dynamically based on tweet volume.

Try TrendsMap for the time being

I am not sure how reliable it is for I am not from NZ.
