Aha - that explains things then.
So, be on the lookout in 3 years for a used Japan-spec Mirage 1.0L "micro-hybrid" in NZ?
EDIT: In Canada, we're allowed Japanese imports, but only 15 years or older. I saw a bunch of different ones (including a handful of Kei class cars) when I was in Vancouver on the west coast a couple of months ago. One of the most popular actually was the Mitsu Delica diesel 4WD small van. Saw those regularly.
