Why?

Why is New Zealand still in a rut - we have been for the last decade - in the UN Human Development Index. (The index is based on a range of data including wage rates, life expectancy, adult literacy, government spending and gross domestic product). Spain, at 13th, has leapfrogged ahead of us as 19th while Ireland has roared past us at 5th.

It seems quite odd when we have tremendous natural resources such as agriculture and are fortunate enough to have the seventh largest water mass in the world.

Wonder if it is related to government policy, tax and regulation?
