Surprise surprise someone else thinks a capital gains tax is a good idea. I should have checked him out first in case he turns out to be a nutcase.

Sensible and fair he suggests. Although the article suggests that "The idea remains unpopular with many New Zealanders, in part because of concerns it could discourage investment in new housing and push up rents, and because of compliance costs." In small part maybe but the main reason must be that they don't want to pay more tax.
