I've blogged the second and third graphs for a reader who wants to compare the NZ situation with the US. (Specific data can be found at Work and Income. Basic DPB rate 
here
Accommodation Supplement 
here and a plethora of extra help 
here. Then I suppose you will have to get tax rates and 
WFF tax credit rates from the 
IRD website.)
The first graph is from the 
American Enterprise Institute. Two and three are from MSD, NZ. They aren't directly comparable but illustrate the same problem.
 
Very interesting, could you get an approximate gross income figure for NZ? The second two charts are very difficult to read.
ReplyDeleteMax, Did you click on the charts to enlarge?
ReplyDeleteWhat do you intend by "gross income figure"? By individual or family? Or the total of all income? I'm not sure.
