There aren’t many people in New Zealand but we have more cars/head than most (~2.5 million cars/4 million people). Then consider not far off half the population live in one city and it is squeezed onto a narrow isthmus between two harbours*. So we do have traffic and now so do our Google Maps (UPDATE 2012-04-13: and Google Earth):
Traffic Conditions for New Zealand on Google Maps
Kiwi automobile commuters, we want to reduce your time stuck in traffic. Today we have expanded our live traffic coverage in Google Maps to cities in New Zealand.
* My Glen Eden to Northcote daily commute is not far short of a cross country drive but only takes about 30 minutes.
