Here is some introductory information and another image from the book Inequality: A New Zealand Crisis by Max Rashbrooke.
* New Zealand now has the widest income gaps since detailed records began in the early 1980s.
* From the mid-1980s to the mid-2000s, the gap between the rich and the rest has widened faster in New Zealand than in any other developed country.
* The average household in the top 10 per cent of New Zealand has nine times the income of one in the bottom 10 per cent.
* The top 1 per cent of adults own 16 per cent of the country’s total wealth, while the bottom half put together have just over 5 per cent.
